RF 24
With an incredibly bright focal length lens, the RF 24-240mm F4-6. Corner image quality at 50mm and 100mm is very good, impressively so for such a lens. Due to the specifications of this lens, multiple exposure shooting is not supported. Summary The Canon RF 24-240mm F4-6. To open the folder on your computer that contains your downloaded files please select the 'Open downloads folder' link on the right of the page• In May of this year, Canon added an 85mm prime to the RF lens lineup. The lens' aperture changes are also quiet and smooth. An extension lock switch is provided and was not needed on the new test lens. 3" 318 x 211mm will fill the frame at the minimum focus distance and the numbers are 4. Nano USM focusing motor and full-time manual focus• The rental companies I recommend below are excellent to work with. This lens is suitable for an extremely long list of photography needs with ideal perspectives able to be covered in a large percentage of encountered scenarios. Extension tubes are hollow lens barrels that shift a lens farther from the camera, which permits shorter focusing distances at the expense of long-distance focusing. Both cannot be used at the same time, but there is one less ring to become confused with. Our standard flare testing uses the sun in the corner of the frame and most lenses show noticeable flaring, especially at narrow apertures, in this test. Performance• The built-in Image Stabilization helps enhance performance, even in low-light situations, and is especially effective when recording videos. 3 IS USM, RF 24-105mm F4 L IS USM and RF 28-70mm F2 L USM. Unless I am using a camera support, I seldom leave home without IS and I often regret those times when I do. Nano USM acts like an ultra-fast version of STM AF, combining the benefits of a high-speed Ring USM actuator with an STM system stepping motor's quiet and smooth, direct, lead screw-type drive system. This is a standard zoom lens and the standard zoom lens geometric distortion statement holds true. 26x maximum magnification capability. This hood offers a good amount of protection, from both impact and, primarily at the wide focal lengths it must accommodate, from bright light. At this moment, it seems easier to list what uses these focal lengths are not optimal for. Use the site's comparison tools to create your own comparisons. Image Quality I mentioned being concerned about the image quality of a superzoom lens. It is not unusual for a narrow aperture lens to emerge relatively unscathed by this test and these results are showing very little color misalignment, mostly only at 240mm. A downside to the variable max aperture is that, by definition, the same max aperture cannot be used over the entire focal length selected. Axial CA remains at least somewhat persistent when stopping down with the color misalignment effect increasing with defocusing while the spherical aberration color halo shows little size change as the lens is defocused and stopping down one to two stops generally removes this aberration. 4 ounces• For additional details about the lens, see the press release below. The extended inner lens barrel has especially little play for the amount of extension. From a center-of-the-frame perspective, use the aperture that provides the right amount of light and depth of field for the shot. That is what we have in the Canon RF 24-240mm F4-6. IS is also very useful for stabilizing video recording and directly related is that "The RF 24-240mm F4-6. This lens is great for a less-seriously-photographing spouse or child. Now Canon has announced the RF 24-240mm F4-6. Alternatives to the Canon RF 24-240mm F4-6. Note that FTM does not work if electronic manual focusing after One Shot AF is disabled in the camera's menu. I never acclimated to that feature and with the R-series cameras, a linear adjustment speed can be configured. The MTF charts were half not bad. 100mm: 240mm: Be sure to find details in the plane of sharp focus for basing your assessment. Compact, Lightweight 10x Zoom RF Lens With a high-magnification of 10x optical zoom and offering coverage from 24mm wide-angle to 240mm telephoto, the RF 24-240mm F4-6. Weighs 26. However, the proper focus distance is in general closely maintained, either naturally through design or perhaps via electronic adjustment. And, Nano USM lenses focus very smoothly. As of review time, Canon does not have RF mount-compatible extension tubes available, but are becoming available. 3 IS USM is an important lens for Canon and its EOS R system. The diaphragm only has seven blades, although Canon promises that it's round enough to deliver smooth bokeh. Remember that lateral CA is another aberration apparent in the corners. 26x at telephoto• 3 IS USM Lens will likely find more homes with amateur photographers, there are reasons for even a seasoned professional to have this lens model. 3 IS USM uses Canon's NANO USM system which combines conventional ring USM AF, and features a diminutive chip-shaped ultrasonic motor that's engineered to help deliver high-speed, smooth, precise and near-silent operation, plus full time manual focus when using One-shot AF. In some lens designs, the plane of sharp focus can move forward or backward as a narrower aperture is selected. The image quality difference made by IS is potentially dramatic. Shown roughly to scale for comparison, from left to right, the new RF 24-240mm F4-6. Lateral CA is back in a big way in the 240mm corners and again, I'll share more in this regard. As always, we'll discuss image quality in depth in this review and while most of us place a very high value on image quality, image quality is not everything. Other features include a locking function for the zoom ring to keep it in place, and a 72mm filter thread at the front for conventional screw-in filters. Lens Image Stabilisation. 3 IS USM lens does not have the clicking mechanism as the previous RF lenses have, providing smooth focusing and exposure control while recording videos. At 24mm, a subject measuring approximately 12. ALL SUCH PROGRAMS, FILES, DRIVERS AND OTHER MATERIALS ARE SUPPLIED "AS IS. Looking at the specs and measurements, the shows the Tamron lens, despite reaching out to 300mm, being the lighter and smaller option, even at full extension. The 10x 24-240mm focal length range in a single lens is simply awesome, ready to ideally frame a very significant percentage of opportunities availed. As an "RF" lens, the Canon RF 24-240mm F4-6. And while both Canon and Nikon released mount adapters along with their full-frame mirrorless cameras which allow the use of DSLR lenses with mirrorless bodies, Sony now has an substantial collection of lenses designed specifically for mirrorless. Focusing Canon has implemented their latest high-performing Nano USM Ultrasonic Motor driven AF system in this lens. There are sacrifices required to design an overall superzoom lens package such as this one otherwise, all lenses would be superzooms and image quality typically suffers at least somewhat. These are mid-sized threads resulting in mid-sized filters with mid-sized costs. 3 IS USM can cover a variety of subjects at impressive ranges from 1. The Tamron has smaller filter threads, 67mm vs. A grey bar will appear at the bottom of your browser window which will contain your download. In this case, the 24-240mm lens delivered much better image quality than the 24-70mm lens. Build quality and handling• This lens has no direct equivalent for comparisons, so I'll select a small handful of lenses for this table and let you use the site's tools to create comparisons relevant to you. Featuring a minimum focusing distance of 1. Perhaps an eagle carrying a bright red salmon lands 30' 10m in front of you in perfect light. Don't expect much corner improvement from stopping down and there is not much room for stopping down at the long end prior to bumping into the softening effects of diffraction. I'd rather call it "efficiency" or perhaps might not have time to do fleeting opportunities. Looking at the specs and measurements, the shows the huge size and weight differences with the EF lens weighing more than twice as much as the RF lens. In the , I see the Canon lens taking an easy win. Unlike the RF L lenses, the RF 24-240mm lens lacks the fluorine coatings on the front and rear lens elements that avoid adhesion of dust and liquids and to make cleaning easier. When the aperture is changed from the maximum aperture by an amount equivalent to one click only, the display of the aperture value may not change in some cases. Customizable control ring• While the corrections are not absolutely perfect, the differences are impressive, aren't they? This lens looks very nice and the fit and finish of construction are excellent. Avoiding the corners due to aspect ratio, not needing wide apertures for adequate light levels, video recording, aided by the dynamic image stabilization feature, is a great use for this lens. 240mm: The second set of 24mm and 240mm corner crops feature lateral CA correction applied. Process your 24mm RAW images using software that does not force distortion correction for a fisheye look. This lens and the color it captured during that event was very entertaining. In order to display image information, please download the latest Digital Photo Professional and Picture Style Editor from the Canon website, or download Digital Photo Professional Express from the App Store. That this size is rather common is also positive. With the powerful Nano USM, this lens allows photographers and videographers full time manual focusing making possible the fine tuning and adjusting of focus while in AF mode. 3 IS USM Lens lies right in the product name. With the right lens profile and software, lateral CA is often easily correctable often in the camera by radially shifting the colors to coincide though it is always better to not have the problem in the first place. This lens does not have those, but it has the other background blur advantage: long focal lengths. Flare is caused by bright light reflecting off of the surfaces of lens elements, resulting in reduced contrast and sometimes-interesting artifacts. There should be only black and white colors in these images and the additional colors are showing the presence of lateral CA. 3 IS USM Lens was online-retail sourced. In the examples below, look at the fringing colors in the out of focus specular highlights created by the neutrally-colored subjects. 3 IS USM range is highly adaptable. If the white bar is not visible you can also access the list of recently downloaded files by clicking the 3 small horizontal lines located in the top right of the browser• Like STM, Nano USM utilizes a focus-by-wire or electrical manual focus design vs. 6-seconds were sharp, the sharp-to-blurred image ratio was still positive at 0. A first for a Canon RF lens is that the control ring serves dual purposes, acting also as a manual focus ring with a switch toggling the functionality. 69" 500mm and a very strong 0. 3 IS USM Lens At review time, this lens does not have an equal and there are very few full frame super zoom lenses to even consider for comparison. 26x, and the RF lens' image stabilization system is rated higher, 5-stops vs. One use that I found was at a car show I visited in Estes Park during some time between my Rocky Mountain National Park workshops I was homeless for an afternoon. Like Ring USM driven AF systems, Nano USM focuses extremely fast — nearly instantly. The RF 24-240mm lens has barrel distortion at the wide end that transitions into negligible distortion and on into pincushion distortion at the long end. The 24-105 uses 77mm filters vs. Quickly hike up a big mountain and shoot from an unstable position in strong winds and a significantly faster shutter speed is going to be needed. A petal-shaped hood is easier to align for installation simply learn the petal orientation while a rounded hood enables the lens to stand on its hood. " CANON DISCLAIMS ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING, WITHOUT LIMITATION, IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NON-INFRINGEMENT. The RF 24-240 has a specified minimum focus distance of 19. The fluorine-coated lenses are noticeably easier to clean. This lens was equally entertaining in the harbors near Acadia National Park. I've personally found this a convenient lens to have available. In general, lenses are not as sharp in the periphery where light rays must be bent more strongly than they are in the center. For example, based on this rating, an ISO setting 5 stops higher, ISO 3200 instead of ISO 100 or ISO 25600 instead of ISO 800, for example, would be necessary to increase the shutter speed enough to compensate for the help provided by this system. Both Canon and Nikon are now in a position lagging Sony in terms of native lenses for mirrorless, and if either company hopes to catch up with Sony in that market—one that looks certain to be the future of camera technology—they will need to be energetic in the development of lenses for it. Image stabilization allows handholding of the camera in extremely low light situations with still subjects or permits motion blurring of subjects with sharp surroundings such as flowing water. At the throw of a switch, the control ring becomes the focus ring. Portrait photography usually does not require them. Edge to edge clarity throughout its focal length, made possible through RF mount technology. Still, it is not too large or heavy to carry even for long periods of time and many miles. Of ultimate importance is AF accuracy and from that perspective, this lens and all of Canon's RF lenses to date performed impressively. Canon's IS systems have long been very well behaved, referring to the viewfinder image always being stable and I do not find myself fighting against IS while recomposing or recording video.

Five-stop Optical Image Stabilizer with Dynamic IS• An extension tube mounted behind this lens should provide improvements ranging from strong to modest over the focal length range. Externally, aside from the missing red ring, this lens looks and functions a lot like its L counterparts. From a focus ring perspective, this knurled plastic ring is mid-sized and positioned behind the zoom ring. The EF lens has the maximum magnification spec advantage, 0. 8-seconds, and a significant percentage of 1. The manual focus ring has an ideal resistance and adjustments are smooth and solidly centered with no unusual framing shift happening. 3 IS USM is a positive indicator that Canon is serious about creating a full-frame mirrorless system for everyone. " [Canon USA] Dynamic IS aids in stabilizing video recording while the camera is in motion. Having 24mm makes life a lot better for landscape photography and having 300mm available takes that lens deeper into sports and wildlife photography purposes. Alternatively, click 'Open folder' to open the folder on your computer that contains your downloaded files• Without correction, the amount of lateral CA present at both ends of the focal length range is rather extreme. Still, the fact that these can largely be sorted through either automatic in-camera corrections or one-click software adjustments means they aren't quite the issues they may have been in the past — and any stronger correction through the optics would mean a compromise in terms of size, weight or cost — and perhaps all three. The ring is clickless, and so provides no feedback in use, although this does make it far more suitable for use during video recording. 78m Telephoto with a maximum magnification of approx. The fast, quiet, smooth Nano USM-driven AF system is superb. The two "C" results shared above have lateral CA correction applied via a simple checkbox in DPP. The 50mm results show some lateral CA and the color shift crossover colors aligning and then reversing happens at around 100mm where little color shift is seen. 3 IS USM Lens is the first non-L zoom model in the Canon RF lineup. ALERTING ALL WANDERLUST PHOTOGRAPHERS, CANON ANNOUNCES ITS FIRST RF TELEPHOTO ZOOM LENS, THE RF 24-240MM F4-6. Fun is another factor that plays into this discussion. While the fun-to-use Canon RF 24-240mm F4-6. The Tamron has modestly less vignetting. In order to use this lens with the EOS R or EOS RP, a compatible version of firmware is required. The same lenses are shown below extended with their hoods in place. Edge• You continue to capture half a dozen great images along with the eagle taking off with the fish still in its talons and the opportunity is gone before your friend has his 70-200mm lens mounted. When paired with the recently announced EOS RP full-frame mirrorless camera, the compact and lightweight portability of the RF 24-240mm rivals that of a Canon APS-C camera system with a comparable EF-S lens. With a 24-240mm range, the RF 24-240mm F4-6. This is the first Canon lens designed for full-frame cameras to feature Dynamic IS and utilizes a CIPA-standard, five-stop image stabilization system. We found that it was certainly possible to still end up with acceptably sharp images at this shutter speed, although not quite consistently. The right focal length provides the ideal working distance and perspective for the composition to be captured. 4 mm, 750g Minimum Focusing Distance: Wide: 1. I could zoom out and capture the entire vehicle or zoom in for details void of people. With Nano USM• Since this lens can, for some uses including travel, take the place of multiple lenses, the overall cost seems quite reasonable. Most of us do find it fun to go out with a single lens and be able to photograph a wide range of scenarios. You are likely looking at a variable max aperture lens and the apertures in the variable range will not be too wide. This position is not my favorite and with the lens' balance point being located here, there is a risk of inadvertent changes being made by the hand holding the lens. This lens will likely be found short for large field sports with significant cropping needed from 240mm captures. Those processing raw files may have to manually remove some more stubborn purple fringing though. The next lens up for discussion is the. These images were manually focused in the corner of the frame. I've hiked a lot of miles with this lens in my pack and in my hand and carrying this single lens is a better option than carrying any near-equivalent combination of multiple lenses. 5 oz 750g , this lens is a touch above what most would consider light. Vignetting can be corrected during post processing with increased noise in the brightened areas being the penalty or it can be embraced, using the effect to draw the viewer's eye to the center-of-the-frame. There are two lens aberrations that are particularly evident when shooting images of stars, mainly because bright points of light against a dark background make them easier to see. While the review-time-latest Canon DSLRs are able to focus a Ring USM lens with good smoothness, these lenses still do not compare to the smoothness of STM lenses and there is considerably more focus chatter sound during Movie Servo AF. The blur and quality of blur seen in the out of focus portions of an image are referred to as bokeh. The diminished form factor of the new lens and EOS RP together, as compared to other full-frame mirrorless camera systems using a similar focal-length telephoto zoom lens, make the lens and camera the ideal kit for travelers who are constantly on the go. 3 IS USM achieves superb speed on focusing while maintaining smooth transition. 3 IS USM Lens is very comfortable to hold and a pleasure to use. 3 IS USM is encircled by a control ring, the function of which can be customized to your preference. Landscape photography is one photographic discipline that presents frequent scenarios requiring sharp corners. The focal length range comparison is not close with the 24-240 obviously having a huge advantage. Consider this lens to have very low amounts of geometric distortion and use the resulting image quality as the big deciding factor for or against this lens. The five-stop IS allows photographers to capture images and record videos with minimal shake, even during nighttime sightseeing or in dimly lit indoor events, without the need of a tripod. You can focus as close as 50cm from your subject at the wide-angle end, and 78cm away from it when you're at the telephoto end, which is perfectly respectable for such a lens. However, few of us find it fun to change lenses some of us even cringe about the potential for imaging sensor dust being acquired during this task and few of us find it fun to physically carry lenses we're not using. By 100mm, slight softening can be noticed and 240mm wide-open results are somewhat soft in the center. Where you buy your gear matters. Similarly-superb is the 5-stop dynamic image stabilization system, adding greatly to the versatility of this rather-narrow max aperture lens. 26x at 240mm Special Elements: 1 Aspherical lens, 2 UD lenses Aperture Blades: 7 circular IS CIPA Standard Correction Effect :5 stops Dynamic IS: Provided Focus Drive System: Nano USM Minimum Overall Length: 4. With understanding and acceptance of its shortcomings, primarily related to corner image quality, the RF 24-240 can easily replace two other lenses in a kit and avoids lens changes, a task that we otherwise might not bother doing laziness or. However, this lens' native amount of distortion is extreme. That is, of course, if you view it as a single lens. Astigmatism is seen as points of light spreading into a line, either meridional radiating from the center of the image or sagittal perpendicular to meridional. That amazing grill is on the front of a 1942 Chevrolet truck. Being a professional-grade L-series lens, the 28-300 is expected to have stronger build quality. In the , the 24-105 has some advantages, especially in the periphery, though the differences are not as strong as one might expect. Overall, this lens is not producing the best image quality available. It's also great to see nicely sharp results, particularly at the telephoto end, where many will no doubt be using such a lens with some frequency. Our measured minimum focus distance range was 14. With the ultra-wide-angles missing, interior architecture and some landscape uses may require a panorama technique when using 24mm. 3 IS USM Lens is compatible with all Canon EOS R series cameras. 3 IS USM Superzoom Lens' headlining feature is its focal length range. The 50mm results are impressive and the 100mm results are my next favorite. When you don't know what focal lengths will be needed, the odds are great that this lens has them covered. Helping to deliver a wide range of image stabilization correction, the RF 24-240mm F4-6. This accelerates AF, Image Stabilization, the Digital Lens Optimizer and more, helping to simplify complex operations and provide a quick and reliable user experience. We're going to look behind the curtains and this is going to be painful. 3 IS USM lens is the first Canon lens that features Dynamic IS for full-frame cameras. 24mm: 50mm: 100mm: 240mm: The review lens does not maintain the proper focus distance throughout the entire zoom range it is not parfocal. The best starburst effects tend to be produced by wide aperture lenses. This is a semi-rigid plastic petal-shaped hood with a matte plastic interior designed to avoid reflections. 21 lens elements in 15 groups including one Aspheric and Two UD Lens• This lens is not compatible with Canon extenders. With an odd-numbered aperture blade count 7 , point light sources captured with a narrow aperture and showing a star-like effect will have twice as many points as aperture blades 14. The RF 24-240 is nicely designed and seems well built with the overall package being comfortable in size and weight. When Canon released its first full-frame mirrorless camera, the EOS R, last fall, it launched the camera along with four lenses designed for the system, which included two primes 35mm and 50mm and two zooms 28-70mm and 24-105mm. While I'm not the steadiest photographer, this testing is done under ideal conditions, indoors on a concrete floor. 3 IS USM lens is equipped with Nano USM, providing users quick, high-speed and precision auto focus AF when shooting video and capturing still images. Videos captured at normal wide-aspect ratios also avoid use of the corners. With these features and more, including a control ring that lets you easily change settings, the RF 24-240mm F4-6. This lens' 24mm corners have decent image quality, especially related to distortion and lateral CA issues, both of which I'll talk about in more depth later on. I have not noticed the image framing drifting while IS is active unless a position change was just made. Coma occurs when light rays from a point of light spread out from that point, instead of being refocused as a point on the sensor. Minimum focusing distance of 1. Below is the back end of a sweet Ford Shelby GT500, the view you are likely to have when on the track when racing against it. 12-pin communication system Pricing and Availability The Canon RF 24-240mm F4-6.。 。 。 。 。 。 。
