Hi,
I don't wish to hijack the thread, but as I'm now using a 1D3 I was about to sell my efs 10/22.
Would Ian care to explain how it might be easily converted, and at what, if any, FL it starts to vignette?
Regards,

It's been mentioned on here a few times so it may be wortha search.
But it basically involves flipping the rear plastic element protector off. That's the simplest way. You do have to be careful in use not to zoom all the way out though as the rear element will foul the mirror. I think from 12mm (maybe 13) you are safe and get no vignetting.
You can advance things a little to make it neater and or safer.
You can neaten the rear up by using a rear price from another lens ( can't remember what one though) .
I remember the 24-85 usm was advised.
Off the top of may head the list of EFS lenses that can convert easily are .
10-22 , 18-55 IS (look up dog toy hack) , 60 macro . I'm not sure about the 15-85 .
The 17-55 never really fills the image circle.
15-85 likely neither if it's a similar construction to Nikkor 16-85 which was tested to always show "key hole" effect on FX.
And for the 3rd party lenses the UWA lenses that do work well are the tokina 12-24 or 11-16 while the sigma 10-20 is said not to fill the image circle. The later 3.5 version may do but I'm not sure
8-16 doesn't.
The problem with theses threads is there seems to ba contingent on here that seem to think its a crime to do any of the above and that you should only use the correct lenses for the format.
The funny thing is some of those will think nothing of shaving the mifprror of a ff body so that can use some adapted Alt lens that would otherwise foul the mirror.
Yeah, or remove mirrors altogether in order to use the Voigtlander M-mount wides. I've seen the pics.
BTW, Tamron 60/2 macro is well known to work on APS-H with no ill side effects. Well, maybe there's vignetting at f/22 and 1:1 - I haven't tested it in extreme setting like this - but not at mainstream parameters. Damn, I sound like I'm a Tamron salesman sometimes.
