Probably a stupid question so appreciate your patience.

Ken Rockwell site describes the lens as "Full Frame" . I would think it would work on a 70d or 7d though. Does the lens lose any quality, features, speed on a crop sensor camera?

Thanks four your counsel.

Yeah it works just fine on crop cameras. And don't use the K Rock for reference on anything, please, for the love of god.

Using Ken Rockwell as reference for camera gear is like using Miley Cyrus as reference for raising your daughter.

This is actually what he states,"...This is a full-frame lens. The 24-70mm range shot on Canon's 1.6x cameras becomes a 38-112mm equivalent lens, which is a very handy range..." I believe he meant that to keep it the 24-70 range.

Here is more, "...This L lens is optimized for 35mm film and full-frame digital, and of course works on 1.3x and 1.6x Canon cameras.

This Canon EF EOS 24-70mm f/2.8 L II works perfectly with every Canon EOS camera ever made, meaning every Canon DSLR and every Canon autofocus film camera made since 1987..."

Short answer yes... but to get the very best out of the lens you will want to get a full frame camera body. There are much cheaper options that will get great results on a crop. So unless you are looking to upgrade your body in the near future I would investigate other options.

I wholeheartedly agree with this. For many of us, 38-112 is a much more useful field of view than 24-70mm.

You may actually like the 24-70 on the crop more than you like it on full frame. That is exactly how I feel about my 24-105 - it is much more useful on my crop body than it is on my FF 5D.


"Your" and "you're" are different words with completely different meanings - please use the correct one.
"They're", "their", and "there" are different words with completely different meanings - please use the correct one.
"Fare" and "fair" are different words with completely different meanings - please use the correct one. The proper expression is "moot point", NOT "mute point".

When I had a 24-105L on my 7D I did not think 38mm was wide enough. At minimum I prefer walkaround lens to have at least 35mm aspect.

Oh really? :rolleyes: What exactly is going to improve if the same lens is mounted on a full frame body??

To be fair, buying a pricey lens like this and not using it on a FF camera is sort of wasteful. You are paying for the extra glass and all that's designed and built to produce an image circle large enough to cover a 24x36mm sensor, but actually using less than 40% of that area with approx. a 15x22mm sensor.

That said...

1. Using only the central part of many lenses can be an advantage... You end up using their "best parts" or the central sweet spot of a lens that's typically sharper and less prone to various types of optical faults than the corners.

2. Some don't like the focal length range of 24-70 on a crop camera, while others love it. Personally I find it very useful. In fact I like a 24-70 better as a portrait lens on a crop camera than on a FF camera. But, sure... a 24mm lens isn't at all wide on a crop camera. So for general walk-around purpose, I pair it up with a Canon 10-22mm or Tokina 12-24mm, which gives me a neat, two lens kit (to be honest I rarely carry only those two... usually I also have at least a 70-200 or 135mm, and often have a 300mm with a 1.4X teleconverter, too).

As to quality... well a crop camera is in some respects more demanding on lenses than a FF camera. While it's true in most cases that the cropper primarily uses the best part of the lens, that's good because the 18 and 20MP croppers have more than twice the pixel sites per square mm than the 21 and 22MP FF cameras, essentially asking the lens to resolve the image more clearly. So a premium quality lens from the Canon L-series line might be an ideal choice, so long as the price tag isn't too much of a shock.

All EF lenses are usable on all EOS cameras. On the other hand, ED-S lenses are only usable on APS-C/1.6X crop bodies (from 300D or original Digital Rebel onward). So most crop cameras can use both types of lenses freely. It's full frame cameras that are somewhat limited to FF compatible lenses only.

I wouldn't pay to much attention to Ken. Having said that I agree with the previous post that if you only have a crop body and you don't have a wider lens having a 24-105 or 24-70 is not very practical. If you also have a FF body and other lenses its not an issue. Depending on what your needs are you may be better off with a combo of the 18-55 stm & the 55-250 stm. Both are very good lenses optically, have a much better range and cost much less than what you're considering. I would even throw in the 40mm 2.8 pancake and you would have a really nice kit that would cover just about everything you shoot.

I get that, for all the reasons that you have already mentioned.

I just don't understand why people can't come in to a thread, and merely answer a question- instead of trying to sell everybody on the merits of the 5DIII and/or 1Dx, and exclusively L lenses. It's like we couldn't take a decent photograph before the advent of 20+MP full frame sensors and third-party/non-L glass.

+1 Alan.

There is no reason for croppers to avoid an EF lens if it is the one that will work best for you, but I don't find this a very useful range for a crop. I have the Tamron 28-75, which is essentially the same in terms of range, and while I find it very useful for certain purposes--it's a great lens for flash work indoors--it is not very handy as a walk around outside. For that I use a 15-85.
