The Zeiss 135mm 2.8 with a Haoda adapter works perfectly on my 5D. I just got a Zeiss 28mm 2.8 with a Haoda adapter and when I shoot, the mirror stays up. There doesn't appear to be anymore of the lens sticky past the adapter into the camera than with the 135. It happens at all focus positions, when I unscrew the adapter the mirror returns. Any ideas or solutions? |

Some Distagon 2.8/28s are reported to not clear the mirror. Whether this depends on copy variations between Distagons, copy variations between 5Ds (more likely), or copy variations between adapters (even more likely), it's still open discussion.
Some 5Ds are actually reported to be more "difficult" with mirror issues. Maybe your 5D is one of them. The things to do in your case are, first, try to change adapter and see if with another adapter you can make it worse. If it does not work, then, you can decide to just use the Contax lenses that are safe mirrorwise, or, if you don't want to accept limitations, grind the mirror of your 5D (or have it grounded).

Mine works perfectly. I have a MM version, but in the past I also had an AR one.
Like I said, there seems to be quite a variation in the copies of the 5D for commerce.
This is one of the things where the 5D reveals it's semi-professional origin.
If it was a 1D, you can be sure you would not have such large build tolerance.
On the other hand, if there was no 5D, I would not be able to afford digital full frame, so, it's ok like that for me. I hope that the 5D mark II will not have this mirror issue. _________________ Orio, Administrator

After measuring the 2 lenses, I found that the 28mm protrudes just slightly more at the part that is next to the aperture lever. Maybe a slight filing will solve this. |

Orio,
Excuse me for the offtopic, but does the Flektogon 4/20 clear the mirror on the 5d? I know you have both. A Flek 4/20 is coming and I hope a 5D is coming too... in the future. _________________ Juanma

After several attempts at cutting and filing, the lens now works with the 5D. It was a combination of the tab and the surround. Thanks for your advice and humor. I'm going out to shoot with it. |

@ Juanma, and in case Orio doesn't see your question:
Yes, the Flek 4/20 will clear the 5D mirror, as does the 2.8/20.

Yes, like Bob said, no problem with the Flek 20 on the 5D. _________________ Orio, Administrator
