Canon RF 24–240mm F4-6.3 is USM Lens, Black

It is a great travel lens for the money. It is light and fairly small, with a wide field to long zoom capablility, so you can get by with one lens for a wide variety of applications from shooting landscapes, rooms, portraits, and even whale watching trips. The biggest issue is that low cost means small diameter lenses and therefore the F6.3 at 240mm for overcast days outside will require higher ISO and/or lower shutter speeds - which may cause a problem for moving animals or birds in flight. The sharpness is very good below F18, and optimal around F10.

This lens covers from wide (24mm) to tele (240mm) with excellent sharpness and color rendition. I know some reviewers have commented on vignetting at wide angles. This should be expected with a lens barrel as long as it needs to be for the 240mm end of the scale, but it is not as bad as they say. If you import into Lightroom, for example, and apply the standard Adobe lens correction for the lens, the vignetting almost disappears, and without losing much of the frame - due to the correction being applied for wide angle distortion.Is this a "real" 24 mm wide angle lens? Of course not! It is really good, but if you need edge-to-edge sharpness without vignetting, you'll need a serious wide-angle prime or zoom lens. There aren't many available for the RF mount at this time, and most will set you back a lot more than this lens costs.For what it is, a not-inexpensive zoom that covers the full range well, it is a great lens. It is not everything for every purpose. I still give it 5 stars, as I think it is an excellent buy for most enthusiasts. A pro would naturally want to add other lenses depending on needs, such as a true wide angle, a portrait lens, and/or a serious super-telephoto.

The media could not be loaded. It’s not the only lens id ever need or want, but it’s the lens that stays on my camera unless i plan on needing something specific. It’s not the fastest, or lightest, you’d probably want something a little wider for real estate and longer for wildlife, faster for portraits and low light, but if you keep your camera with you at all times and want to be ready for 90% of anything it’s great. 100% would buy again.

I only used it once and that was for a live music performance. I had been using the wonderful EF 18-135 on my 90D with the power zoom attachment which is wonderful. BUT I decided to switch to two RF bodies (R6's) and try pulling zoom manually with one of those rubber band attached handles and that did NOT work out too well! The darned zoom ring is SO tight that there was no way to make a smooth zoom pull. I think the whole RF line is great for stills but for video we are simply not there yet. If you are just shooting stills, this should serve you well but that darned zoom ring is WAY too stiff. I would much prefer something easier to turn that this one. IQ seemed to be OK on the one day that I tried it before returning the lens. Way, way, way too stiff IMHO. Happy shooting out there!

A very useful and convenient general purpose lens - avoids the need to deal with multiple lenses for the EOS R series cameras. Some reviewers complain that this lens has excessive vignetting at 24mm wide angle in RAW. This lens was certainly designed to use post-processing software lens correction. With this in mind, Canon was able to provide an extremely versatile lens at a fairly reasonable price. Of course, it's not an L lens but I've found its sharpness to be much better than acceptable and its image quality very good when used with the lens corrections function in Lightroom. It compares favorably with my other high quality lenses.

Long story short: If you're the kind of person who just doesn't want to miss a shot and will use the camera's JPG 90% or more of the time, this lens is an absolute joy. The versatility is marvelous, the quality is fantastic, and you will capture so many moments perfectly that might otherwise simply be missed. I picked this up in lieu of a more traditional 24-105mm lens, so despite my primes and more dark/bokeh-oriented 24-70mm f/2.8 lens, this is often my daily walkaround choice with the 35mm f/1.8 in my pocket for darker scenes. And the pictures speak for themselves; it captures nearly every moment beautifully. Highly, highly recommended!

I'm using this on an R5 and it makes for a fantastic walkabout lens! Very happy with. Extremely sharp pictures.

I bought this lens to take on an overseas vacation. The focal range is great, but this lens has some serious barrel distortion and vignetting when used without in-camera lens correction and/or profile correction in Lightroom. To correct the vignetting, the image is slightly cropped and the corners brightened.... so 28mm is more like 30mm after software correction. And, since the corners are already processed (lightened) by the software correction, if you try to increase exposure or vibrance in Lightroom, the corners look blown out because they've now been processed twice. I ended up selling this lens.
