hi
anyone know about whether these lenses can be used on micro 4/3 like ep1, focus to infinity?
thanks

About any lens can be adapted to m 4/3 camera due to the short register, but I haven done or heard about Krasnogorsk movie lens Adaption yet - maybe I should start (another) project...grin.

Just read that Krasnogorsk lenses have either bajonet or M42 mount; the latter would be very easy to convert though.

thanks klaus, let me ask you, if they have a bayonet mount is there now an adapter to allow use on m4/3?

Not that I would know of one. So either you wait for our chinese friends to discover that possible market and make one or have one machined. Most likely I will have a look into that, since I'm anyway working on some other ones...but these are/will be "Made in Germany" and with our hourly wages here that usually ends up pretty expensive.

thank you klaus. well,if you come up with one, let me know. perhaps that will be a new business venture! Laughing

btw, are you considering selling any of your tevidon lenses? if you i would be interested in hearing what you would ask for any in the 25-50mm range.

thanks again!
tony

I am currently in the middle of a project of adapting a bayonet Konvas-16 lens to Canon EOS. The lens is 16OKC7-200-1 (which basically means it was intended for 16mm cameras, 7th version of the barrel, 200mm focal length). The lens itself is 200mm f/2.8. It is a classic Tair design which covers even the 70mm frame (Canon's FF should be no problem). Unfortunately, it has a very narrow rear mount, so this will have to come off.

Sample at f/2.8 (note how it has some vignetting due to the narrow mount):
