Well,
The 5DMkII arrived few days ago and i had the chance to check some lenses - Mr. Spreadsheet Boss, please update - if it's not already done...
Pentacon Prakticar MC M42 50/1.8 - Plastic anti-dust protection protruding part shaved, and now it's ok.
Pentacon Prakticar MC PB 50/1.8 - Same as above.
Pentacon Prakticar MC PB zoom 35/70 3.5-4.5 (almost sure it's a Japanese version, not GDR). Hits the mirror, can't be used, no mods possible without dismantling the lens and seriously grinding the back barrel, which i'll not do, prefer sell these lens.
Pentacon 30/3.5 Meyer-Optik Lydith version- hits the mirror, but possible to use in live view mode, if the infinity lens position is not set when the mirror moves up and down. Annoying, prefer to sell these lens too to someone who has a APS-C or other sensor smaller than full frame.
Leica-R Summicron 50/2.0 1CAM fungus version  with adapter Leica-R-EOS - Ok, as spreadsheet marked.
Carl Zeiss Jena Sonnar 135/3.5 M42 with cheap M42-EOS adapter: OK
Asahi SMC Takumar 135/3.5 M42 with cheap M42-EOS adapter: OK
Pentacon Prakticar 2.8/135 MC PB (Meyer-Optik Orestor project) - Same shaving operation as above with 50/1.8 PB and then can be used with big_is PB-EOS adapter.
Pentacon Auto 4/200 MC - Same procedure as with other PB Pantacon, and OK with big_is PB-EOS adapter.
Carl Zeiss Jena Ddr Tessar 2.8/50 M42 - Ok, using cheap M42-EOS adapter.
Some days more and i'll post myself the smyles and tears using the MarkII with Mir 1b and Takumar 35/3.5.
Keep the wheel rolling,

Since I cannot access the spreadsheet I will give a verbal report on my latest experiment.
I have had the final Kern MacroSwitar version sitting on a shelf for quite some time. It came in a M42mount with an Alpa adapter.
Exept for the Extensan versions and some Kilfitts, the Al mount precludes use on EOS. Unscrewing the adapter, however, allows mounting on EOS. Alas, infinity does not seem to be possible. The mirror hits when focussing beyond som 5 to 10m.

I have recently acquired a 5D mk ll, am I right in thinking that a lens could cause issues if any part of it protrudes beyond the mount?
My Planar 50/1.7 has a tiny bit sticking out while my Nikon 50/1.2 has a metal prong which I think is there to protect the rear element if the lens is placed on a flat surface (why would you do that?)
I don't know the best way to test for problems, safely.

A fast way to test if a lens will hit the mirror of EOS FF is to observe the back part of the lens with the adapter installed: if any part of the lens protrudes from adapter it will probably hit the mirror when focusing the infinity. You can test also with a rule, moving it over the back side of the adapter, to check if it touches the lens back. Some lenses deserves a shaving intervention and it's ok - Mir 1B, some versions of Helios 42, and so on. Other lens have the back element to far into the camera body - Takumar 3.5/35 f.i. - and can not be used at infinity.
You'll not brake the mirror camera just testing it, I did several times, gently touching the mirror, and the Mk II I own is ok.

Thanks for that.
I tested all my lenses on the 5D today and only the Nikon 50/1.2 was a problem. The small metal tab was easily removed and now it works perfectly. The Planar 50/1.7 does have a little bit protruding from the back but it didn't interfere with the mirror.
All in all, I'm delighted.
(the Samyang 8/3.5 is for crop sensors, I'll use my Zenitar 16mm fisheye instead)

In theory, a notched rule where the notch matches the clearance between the rear of the mount and the mirror would make determining whether the mirror will catch or not much easier. Different notch depths could then be used for 5D/ii/iii and 6D. If the data was available to calculate the clearance profile.
Is the spreadsheet messed up again? - the red highlights aren't making it easy to read the red text in some of the boxes. At least one line that says "Yes" appears to be based on an Ebay observation rather than direct experience (Rolleinar). |

paulhofseth wrote:
This "Salt ruler" is certainly a good method to get a rough impression of which optics fit without modification.
A refinement: Since the edge of the mirror moves in a circle segment (except for the more complicated ones that actually retract a bit ), a corresponding curve can be cut in the ruler.
This will also be useful if you decide to file off offending bits where only a millimetre or so is in the way. Since the lens is more durable than the SLReletronics, you may of course prefer to modify the mirror - and make a new ruler with a correspondingly deeper notch.
On the other hand you may decide that the risk of mirror-shavings inside the shutter and sensor combo together with the probability that lens will have to put up with a succession of longer mirrors favours lens vandalism. Suction needed for to continuously removing debris risks messing up shutter curtains when filing the mirror, while lens mechanics are far more robust.
I found that filing a bit off the lens metal to correcting for mirror movement made it possible to use the wide end of a 21-35 zoom at infinity.

Nice to see the Pentacon Prakticar 2.8/135 MC PB and the 50 working. Just found them really cheap.
How do you shave the part off. I guess it might be easy to see, when I get them.

I bought an old EOS film camera to test for mirror hit. (Canon Rebel K2) Works fine!
