My DIY 35mm for Leica lenses...

sunriseseagull, i have atest mule Cossina 40 1.4 for right now with a few Lieca M
lenses on the way...

Now that the holidays are over I can get back to my adapter. I noticed a bit of
smearing and ghosting on this image that I've tried to diagnose. The ghosting
was caused by a DVX focus error on my part. The smearing is a different case
all together which a larger diameter achro should fix.

More footage to come.

Thanks, Inexistence!


I was told that the Leica M serries lenses were not possible to attach on any 35mm adapter. Please let me know the results when you got your Leica M lenses! Thanks!

Where did you hear this? I'm curious. The Cossina & Leica M mounts are interchangable as far as know.
 
I was in the market for an adapter myself and have a friend who has a set of Leica M lenses. But as far as I know, M2, Letus35, SGpro,... neither of them supports Leica M lenses (with the exception that the SGpro supports Leica R lenses). Please correct me if I'm wrong. Thanks!
 
My fault. I get what ya mean.
The back focus distance is pretty short for M mounts. 27.8mm to be exact. I wonder if the M2 guys could manufacture a short M mount to accomodate?

The first footage you posted looks pretty sharp and grain free. Any chance we can see some full scale footage to evaluate this better?

Are you planning to sell this adapter or are you building it just for fun for your self?
 
Car3o, it was a stereolithography piece. The plastic is extremely durable. Expensive
though for individual 3d prints.

rawfa, I have some extreme low light footage that I'll try to upload soon. As far as
selling it I might be up to building some custom units. I can't see myself selling
a whole bunch because there are cheaper better alternatives... nikon lens and
Daniel's vibrating combo seems to be a great deal.

I'm actually working on an HD version now and that might be a few weeks off
from today. I'd like to couple it with the Canon HV20 in April.

This isn't the exact machine that was used but, its the same
process of building an object from 3d data by creating extremely
thin layers of liquid plastic. There are a number of houses who
can perform the build for you.

It's good for prototyping and that's about it. Like I said before
it's pretty expensive; still somewhat reasonable. Would never
use the polymers as a production material though. I think most
people would prefer more exotic materials & construction like the
Brevis or one of Dan's Felix devices.

I'd like to build one using nothing but aluminum myself. There is
actually a process that can take the plastic piece and apply a metal
coating of sorts. I have not explored this route yet.

With Red, SI, and VRI models availble for rent 35mm adapts might become
a thing of the past. I'm still going to pursue a smaller adapter for
personal use though. I know I won't have the money or enough
experience to handle a Phantom 65 or Red at the moment.
