CZJ Tevidon lenses on DSLR

[zhang xk]

Hi all,

I like to explore the potential of those gears that otherwise would have no use. Those CZJ Tevidon lenses were designed for HD 16mm sine cameras, and these are APO glasses corrected for 400-1000nm wave lengthes, and no focual adjustment is needed for infra-red films. Those with a focual length longer than 70mm could be used on a DSLR and covers the full frame.

Here is a 70/2.8 lens converted to M42 mount and used on a Canon 300D. The 1st iamge is a resized full frame, and the 2nd is a 100% crop without PS.

These are some of the sharpest lenses I have used so far.:) Some of these are still been made by Doctor-optics.

Cheers,

Zhang

CZJ Tevidon 70/2.8 and 18-90/F2 in M42 mount.

I used a M42 ring for the 70/2.8 and a spare M42 mount for the Russian Nikon mount 100/2.8 lens for the zoom Tevidon. The 100/2.8 lens came with both mounts that can be changed with a screw driver. I drilled 3 holes on the M42 mount for the 18-90 zoom Tevidon.

In case you have such a lens and want to make use of it, this is FYI.

hi there

Can you mount Tevidon 1.8/16 on Panasonic G1? Does this lens C-mount?

They say it has C-S mount -- is this true?

Thanks..
