I just bought a Zorki 2c that will be arriving shortly I have an Ektra Ektar 90mm 3.5 without a real home My plan is to make a Zorleictra Right now the Ektar is epoxied to a kodak pony which was good enough to test the lens out through my bedroom window. I wont be able to focus by mechanism but rather I turn the barrel out manually ..I don't have the skill needed to properly fashion a thing that couples to the focussing of the ektar and I don't plan to pay anyone to do so, either I'll have to shoot a few test rolls to get the correct markings for near objects I don't know the registration distance of the Ektra. I think it's more than the Leica 39mm so I should be fine If you've done this before with a lens how did it work out? Were you ever able to trust the epoxy? What kind of epoxy for metal to metal/leatherette? I used loctite wood glue to secure the homemade "mount" made out of filter holder plastic It seems strong but Did you like the results? I'm never going to buy an Ektra for 1K so I figured this would work well enough to utilize the lens. This is just a bedroom window photo with lens at f11 and lens cap for shutter.
