When attached to EX1, can any 35mm lens be attached (canon 50 1.4, 85 f1.8 300f4 600f4. ) If so, are they 1/1 or can there be a multiplier factor? How about image quality? It would be really neat to isolate wildlife.

thanks

When you purchace the Letus35 Extreme you choose a lens mount you want (Canon FD, Canon EF, Nikon..). You can buy a few mounts and they're easy to change. This way you can use a wide variety of different brand lenses.

The quality is dependant on the lens you have. So if you have a good telephoto lens it will look good.

Im not sure what you mean by the multiplier factor but if you mean is 50mm the same field of view as photography 50mm yes it is. Although you can zoom on the ground glass somewhat so in essense you can go even more tele than the lens would allow.

Do you retain any functions of the attached lens - auto focus, iris, image stabilizer, or does the attached lens become fully manual with the iris wide open?

You loose all autofunctions of the lenses you attach to the Letus. The Letus doesnt have any electronics to control the lens you attach to it. So automatic only lenses dont fit the 35mm adapters. You can (and must) manually choose iris and focus.

If your lens has a built-in image stabilizer... I dont know about this one. But using the image stabilizer of my sony handycam with the Extreme doesnt look very good. At the end of a pan/tilt the IS tries to correct. (Has something to do with the vibrating ground glass maybe.) I keep IS turned off on my camera.

The letus does not have a powered connection to the lens. If you try using anything that has servo motors for the iris, focus or zoom that cannot be overridden manually, you will have no image. When the servo shuts down, especially on the iris, there is no picture, the iris will remain closed completely.

I hope this explains it alittle more...
