Mirror lenses!

Have you just found a Vectis? Good for you. If you saw my post regarding my own experience, the helicoid approach did not work well. To get it to work at all, I had to use a Vectis camera to focus the lens at the approximate range I wanted to use it, remove the lens without turning off the camera, so it didn't reset to infinity, and then I could use the helicoid in a very narrow range.

Whatever you do, don't modify the lens; a MonsterAdapter will be available again in the near future. I know this from direct information.

Thanks - I do have the LA-VE1 adapter but alas no Vectis 400 mm mirror lens

Nice!

The mirror lens can get quite busy

Welcome back to cats.

I   Don’t know Mike. Silly enough I never tried it. I handled it as part of two different systems. Never the two should be mixed.
On your photos.
I recognize many of your shots. They made enough of an impression to me at the time.

Leo is a welcome guest at dyxum meetings.
That’s where I see him. Taking great photos of subjects I didn’t even see or didn’t dare to photograph with lenses I could never buy, missing the skills to use them.
