Which EF-S lenses on FF?

So which lenses designed for APS-C crop bodies also work on Full Frame? Which ones work on APS-H crop bodies?

I have one I can vouch for - Tokina 11-16 f/2.8. It works on my 1D from 13-16 and on my 5D at 16.

No Canon EF-S lenses physically fit on FF or APS-H, because of the rubber ring at the rear.

If you remove that rubber ring I know you can use the 10-22 on APS-H from a certain zoom setting.

The Sigma 30mm f/1.4 works on APS-H if you use at a wide aperture. Once you start to stop down the vignetting increases.

If I'm not mistaken, all non-Canon lenses are EF mounts, even the ones that are designed for crops. So they'll all fit on full frame, but they may not work at all focal lengths.

Let me clarify the question. Yes, I know that EF-S lenses have non-compatible mounts (but can be easily modified) and that non-Canon lenses all use standard EF mounts.

Since the mounting issue can be addressed, the question is which lenses, though designed for APS-C, perform to some acceptable level on APS-H or full frame?

10-22mm works well on a APS-H sensor at 12 mm and above. The tokina 11-16 is known to work at 13mm, and the 30mm F1.4 sigma will also work. Not sure how any of these will work on a full frame but I assume not well without some heavy cropping.

For the newbies who may not fully understand the stuff above:

If you modify an EF-S lens to fit on a standard EF mount such as that on the 5D cameras and use the lens on that camera, there is a very high risk of crashing the 5D's mirror into the rear of the EF-S lens. It would be a smart idea to totally ignore the concept of modifying Canon EF-S lenses to use on cameras that normally cannot accept them. Instead, use third-party "digital only" lenses if you must experiment with the larger format cameras.

Thanks Skip - You're absolutely right. Before I mount any "digital only" lens on my 1D or 5D, I very carefully compare it to one of my EF lenses. I check to see that nothing projects from the digital-only lens at all zoom and focus settings. If it stick out more than my EF 85 f/1.8, then it does NOT go on the FF body.

The tokina 11-16 is a ef-s lens, but you can use it at 14-16mm without vignetting.

I'm going to go with "none".
If a lens produced acceptable performance on APS-H or FF, there would be a positive disincentive for Canon to put an EF-S mount on it to prevent it being used that way.

It's not an EF-S lens. It's an EF lens designed for crop bodies. There's a slight difference.

EF-S lens: designed for crop body, rear element protrudes so that unmodified, it would destroy a FF mirror

EF lens designed for crop body: can be mounted on FF with no physical damage as the rear element does not protrude, but will likely vignette at some or all of the way through the focal range

EF lens designed for a FF body: no issues whatsoever on any camera, crop or FF

Sorry, I'm new to this but this statement confuses me... what EF lens was [edit: are specifically] designed for a crop sensor? - I mean APS-C (1.6)?

My 10-22, ring removed, worked from 12-22. I never tried it at 10-11mm. Moot point since it vignetted below 15mm...so perfectly useable from 15-22.

As far as crashing into the mirror. I think I've done that about 20 times with my CZ 28/2.8 although it is getting caught on the way down and not up.

Lenses can have EF-S mount, or EF mount; EF-S mount will not physically mount on FF (EF) bodies unless some physical modification of the lens is performed.

Independently, lenses can have an image circle limited to APS-C frame size, or they can have an image circle large enough for FF size. Zoom lenses at shorter FL setting might be too small in image circle size to fully cover the FF frame size without vignetting, at at longer FL setting the vignetting does not occur.

All EF lenses inherently cover a smaller crop sensor (15x22mm) , since they cover the larger 24x36mm FF sensor. All lenses for FF work fine on crop bodies; the inverse is not true (some EF-S lenses not only vignette, but also protrude too far into the body and would cause the reflex mirror to crash into the rear of the lens and ruin your day.)

The third party (Sigma, Tamron, etc.) lenses that are labelled "digital only" or some variation of that are all EF mount lenses, but they have a narrower image cone than EF mount lenses designed for 35mm film format cameras. These lenses, if used on a 35mm film format camera will generally vignette rather badly. However, they cannot cause mechanical problems with the larger format cameras because their parts don't go any deeper into the mirror box than the Canon EF protocol dictates.
