'Full Frame' Lens On 60d

Evening folks,
I was reading somewhere about lens that fit cameras such as the Canon 60d, not being compatable with full frame cameras.
So, with this in mind, how about the other way round.
I have a Canon 60d. My nephew has a 5d mkIII and uses a Canon EF 24-70mm f/2.8L II USM and gets some incredible results.
I appreciate that a lot of this is down to his camera, but was wondering if this lens will fit my 60d and also would this lens on my camera be able to achieve very good quality results or just be wasted?
Any chance that anyone has this combination?
Thanks all

EF lenses will work on APS-C cameras (but the crop factor applies here) and FF cameras.
EF-S lenses by Canon will not work on FF cameras without a modification to the mount by removing the plastic/rubber gasket on the mount; third party EF-S lenses will work on FF cameras albeit with most of them having hard vignetting on the resulting images.

If you have both bodies, and an EF lens such as your 24-70L II the combination will work fine on your 60D as well as a FF body like the 5D Mk III. The effective field of view on the 60D will be 38.4mm - 112mm however so you should take into consideration the focal lengths with which you would like to shoot on the 60D and 24-70L combination. Optically the 24-70L II is a stellar lens so it will produce great results regardless of the body it is on.

they work the other way...getting a lens like the sigma 18-35mm f1.8 would allow you to get similar results to a 24-70L on a FF camera

Cropped sensor cameras (Rebels, 60D) = Either EF-S lenses or EF lenses.
Full frame cameras (5D3) = EF lenses.

I used a 24-70mm f/2.8 on a few crop sensor cameras (including the 40D) before I switched to full frame cameras. The results are fantastic. The lens is a bigger factor in image quality than the body it is put on.

The advantage of buying EF lenses is that if you decide to get a full frame camera later, you aren't stuck with lenses that aren't compatible.

Another advantage of EF lenses on a crop sensor body is that you get a 1.6x magnification advantage. If you have a 200mm lens, it is now a 320mm lens on a cropped sensor body. The downside, of course, is that it makes it more difficult to go "ultra-wide". To get a 16mm equivalent on a cropped sensor camera, you need a 10mm lens.

EF lenses on a cropped sensor camera will also show less vignetting than it would on a full frame camera.

A disadvantage of EF lenses is that they will be bigger than a similar EF-S lens. This also causes the cost of manufacturing these lenses to be higher.

So despite the fact that your cousin has the better camera, you have the advantage of a better lens selection & universal compatibility with all Canon SLR lenses made from 1987 onward.

Another point to consider:

Don't buy EF lenses just because they're FF compatible. Buy the lenses that you need for your camera. If you have EF-S lenses, you can just sell them off when it's time to go FF. Example: Opting for a 16-35 f/2.8 or 17-40 f/4 on your APS-C when there's the EF-S 17-55 f/2.8 IS which is better optically than both L lenses.

Thanks very much for the replies folks - all very much appreciated

So, are you saying if I have an EF-S 200mm lens on my 70D it's a 200mm lens but if I have an EF 200mm lens on my 70D it becomes a 320mm lens? Or have I misunderstood the intent of the bolded portion?

Get a Tamron 28-75 f2.8. They are amazingly sharp and decent wide open. I have used one on my 40d for years with good results. Now with my 5dc I get even better results...

In reality I should have said "the advantage of a crop body". Both EF & EF-S lenses get the same 1.6x calculation applied to them when put on a cropped sensor camera. Example being that a EF-S 10-22mm on a 70D would be the 35mm equivalent of 16-35mm. A EF 16-35mm on a 70D would now be the 35mm equivalent of a 25.6-56mm lens. A EF 16-35mm on a 5D (full frame) would just be 16-35mm.

No, EF-S or EF makes no difference, a 200mm lens is a 200mm lens.

On a crop, a lens will "appear" 1.6X longer than on a full frame because of the crop factor, but it doesn't change the focal length. If you cropped a full frame image, to 1/1.6 the size from the center, you would get the exact image produced by a crop camera.

Buy a lens that suits the focal lengths you intend shooting on your 60D.
If you like shooting at (say) 35mm on your 60D, get a 35mm lens makes no difference if it's EF or EFS.
EFS fit crop cameras.
EF fit crop and full frame.


You will get people saying that (say) a 35mm lens is like a 56mm lens on a crop camera.
It isn't...

Put a 35mm lens on a full frame camera and the view will look different.
It will show what appears to be a "wider" image.
It won't be more "zoomed" out, it's just the 60D is a crop camera (having a smaller sensor) so it has cropped the edges of the image.

The 35mm lens is still a 35mm lens, regardless of the camera.
All a crop camera does with the edges of the image is crop them off.
The image then just appears more "zoomed-in" on a crop than a full frame.

Thus the image might look like it's taken with a 56mm lens, when it reality it's actually a just 35mm lens with the edges cropped off.

This should explain it...

Completely agree with everything. However to get the cropped image equivalent on an APS-C camera, will we not need a 1.6x equivalent on a FF?

In other words, if you have an image taken on a 60D (or any Canon APS-C camera) with a 100mm lens, to get an equivalent image on a FF camera, will you not need the focal length to be at 160mm (on the FF)?

100mm is 100mm as far as focal length. The full frame camera's image can be cropped in post and achieve the same image.

160mm on full frame may have the same things in the picture, but it will look differnt than the 100mm shot on a crop body camera.

Shouldn't it look exactly the same since you'd be shooting from the same spot

100mm on a cropbody vs cropped 100mm on full frame will indeed look the same.(the full frame will be of higher quality since it is using the center portion of the lens)

In the second example I gave, the depth of field difference is what i mean by it looking different. the compression of distance at the higher focal length will have a different look.
