I've already heard about this kind of "method", used to gain the necessary space on the 5D for particular manual lenses...but surely it simply looks crazy Shocked i hope the mirror won't be affected, btw good luck and have fun with manual focus lenses on it! Very Happy

It is not THAT crazy IMO, not too difficult to do afterward of course.

When I bought EOS_5D, I was dreaming to use all those Prakticars
without any crop(crap?) factor. Cool

Since I am still a Prakticar collector so that I have to show some examples
shot by those CZJ lenses, which are relatively unknown to photographic
community. So I willingly become a scapegoat or guinea pig. Very Happy

I have just shot with Planar 55/1.2 at wide open.

Indeed it's a cool idea Very Happy i often think about how could my lens would look on the full frame, surely i won't need to use 28-35s as cropped 50s Razz

Overall my 135 Tak would became more suitable Confused



Hmmm full frame is temptating >_< and i already have a 40D

Also you can use these lenses at infinity range,

Flektogon 20/2.8, Flektogon 25/4, Pancolar 80/1.8, Pancolar 50/1.8(?),
PORST AUTO 1.2/55 (K-mount), EF-mounted Canon FD 55/1.2 S.S.C.,
EF-mounted MC Rokkor-PG 58/1.2, EF-mounted MC Rokkor-PF 50/1.4,
EF-mounted MC Rokkor-PF 85/1.7, SMC Takumar 50/1.4, CJZ tessar 50/2.8,
AND all the Prakticars. Cool

And possibly some other C/Y lenses, though Prakticars are my main goal of
mirror shaving. Yes ePay seller's PB->EF adaptor helps a lot here too.

Just curious...since the mirror is a moving part, is there any chance that the cracked mirror may shatter sometime in the future? Otherwise...that was a mighty gutsy bit of DIY!

It might. Very Happy

5D's mirror had many incidents of dropping under very high humid
environment, though I did not hear any more of this problem.

The thin mirror (seems glass) is glued to rubber like material,
which supports the mirror and sub-mirror. It maybe a compound of
rubber and hard plastic, this is hard to shave due to its softness.
