It is designed for half frame, so not a wide lens , just half frame lens. I am unsure it is draw full frame or not.

Yes, it will work, how good the corners will be I don't know and it might vignette slightly as it's designed for half-frame.

A Jupiter-12 might suit you better, stunning lens although not that wide at 35mm.

I-69 has 28.8mm register, M39 is 28mm so you need to open the lens and file down the focus stop by 0.8mm, apparently it's a simple job.


I've seen the lens modified to LM39 on a Leica M9 - very strong vignetting.
But it might work for APS-C

Be interesting to see if it does cover APS-C well as i would love such a tiny wide lens for my NEX.

Many people have done this conversion now, you have to mod the lens or the adapter slightly to achieve proper focus,but seems half decent once done. This is just the first sample set i found through Google on Flickr (not my photos) however there are many out there if you look.

Be wary. There is an informed warning/explanation in this thread. http://www.mu-43.com/f40/industar-69-hack-hard-way-its-still-easier-than-you-think-20477/

I have a modified I-69 on a m43 adapter, but I find it awkward to use and I don't rate it highly.

Cheers

I have it, and have used it on my NEX-7, it causes color shift in the corners, vignetting is not that bad, Cornerfix does improve things.
there was smearing with mine when W/O, I'm not sure if that is the lens or my NEX-7's finicky sensor.


Re: modding to get infinity, the link posted above your post is what I needed to do to get mine there, my advise is to do the stop pin first, then test it, if you still don't reach infinity(which was my case) then you need to remove some material from the center part.
Edit: was beat to it. Laughing

super easy mod:

a bit more involved method if you don't reach infinity after doing the above:

Here is an uncorrected test shot on my 7:


A shot with Cornerfix, which shows the loss of detail/smearing, the center is very sharp.

What a fantastic set!

I love the composition on that snowy landscape.
Hardly ever see vertical panoramas, looks amazing.
And... one of the few baby shots that I've ever liked too...
