I have a Canon 77D and have been thinking about purchasing the Canon EF 24-70mm f/2.8L II USM Lens. My question, would the lens produce sharp photos with my crop sensor camera or would it be better to stay with EF-S lenses? If so could someone recommend an EF-S lens that would be some what comparable in performance to the Canon EF 24-70mm f/2.8L II USM Lens. Thank you.

The 17-85 efs lens is a good lens I use one on a Canon m50 with an adaptor and get excellent results.

There is no reason that the lens would not produce sharp images on your camera.
If you think in terms of full frame equivalent focal lengths, it will be the approximate equivalent of a 35-105mm zoom on your camera from a field of view standpoint...from a mild wide angle to a short/mid telephoto, depending on whose definitions you use. I have a lens of this range that I used on a crop sensor camera and was pretty happy with. Just recognize that it won't do a lot for you at the wide end on your camera.
That lens will, more than likely, produce some very sharp images. The reason is the crop sensor is using the central portion of the image circle. That is where a lens is usually the sharpest.

The drawback of the 24-70 lens (or similar 24-105 options) is you're not very 'wide' on the 24mm end due to the crop factor. Rather, your 'wide end' is an equivalent 38mm (24 x 1.6).
Personally, I think the EF-S 10-18 IS is a better choice than the 24-70, where you're paying a premium for a full-frame lens that doesn't deliver the useful focal length zoom when mounted to a cropped sensor body. The full-frame options of the 17-40L or the 16-35 f/4L IS are that 'wide' to 'normal' zoom range, similar to the EF 18-55 IS, just a heck of a lot more expensive and ruggedly build.
The EF-S equivalent for the useful general focal length zoom of the 24-70 / 105 options is the EFS 18-135. It may not have the absolute sharpness of a full-frame lens costing 3x more nor the constant f/2.8 aperture, but the EFS 18-135 delivers the useful focal length for general photography, similar to the full-frame lenses.
I've found the 'sharpest' options for Canon's crop-sensor bodies are the many EF and EF-S prime lens options. The primes may seem less flexible, but if seeking the sharpest image ideas, find a prime focal length that fits your shooting style.

I am not a Canon shooter so I can't make any alternative recommendations. However, in general a full frame lens will give an overall sharper image on a cropped sensor camera.
Lenses generally are sharper in the center with sharpness falling off on the sides and corners. Stopping down the aperture will usually improve sharpness in those areas.
With a cropped sensor you will not be seeing those problematic areas and will be shooting at the "sweet spot" of the lens.
I used the lens on both crop and full frame cameras and it gives sharp pictures on both.
Thanks to everyone who replied.

I used a 7d for years and when I bought it I bought a 24-105 L lens to go with it. My thought was that bodies come and go but lenses are forever and that I would eventually move up to a full frame camera. The lens performed flawlessly on the 7d and is now performing flawlessly on my RP. Meanwhile my granddaughter loves the 7d.
Buy a lens that does not limit your future. You wont regret it.
I'm a Nikon guy, but wondering why the Canon 17-55 2.8 IS isn't mentioned here among Canon users.
Nikon has a 17-55 2.8 for crop sensor that's a pro-level lens ...actually made before Nikon had a full-frame body.
Is there no one here who has used the Canon? Just Curious.

The Nikon lens is more of a comparison to the full-frame Canon lens, two unique lenses in the history of the brands. The EFS 17-55 f/2.8 really isn't in the grouping of these other two.

You are always dead on in your analysis! I agree totally. Maybe he's might consider a used MARK II or III? I can't really see "wasting" the wide angle on that lens. Tbe the 10-18 would be a much better choice IMHO

Yes. There is nothing inherent in a lens that is designed to cover a larger sensor that would make it a poorer candidate for a crop sensor camera than a lens designed for the smaller sensor. In fact, since lens flaws like barrel/pincusion distortion, vignetting and chromatic aberration tend to increase the closer one is to the corners and edges, any these flaws on the 24-70 will likely be outside the crop sensor area. If you need an F2.8 maximum aperture, the EF-S 17-55 F2.8 USM IS would be a very good candidate.

The site I posted the link to has some full frame lenses tested on crop sensor cameras, and you can compare edge and corner sharpness to EF-S lenses - and you'll find that typically there is more consistent sharpness across the frame with the bigger lenses.
If you are contemplating getting a full frame camera down the road, then get the 24-70, otherwise getting the 17-55 would not be a step down in optical performance.

Nothing wrong with the 24-70 except cost, weight/size and it is not really wide on a crop frame.
I use and highly recommend the Sigma 17-70 2.8-4 OS macro. especially if budget matters.
