Dave: that sounds interesting. Use it and post some images on here!
Reinhold: I saw this, and attempted to replicate it with a close-up filter that i had. it seems that i don't have enough bellows draw for the single-meniscus, it's awful! oh well i guess i'll be using plastic optics and smaller format cells on a copal shutter os something. Not really sure what is going to happen at this point, but we will see. It's funny because my other lens is a schneider, which, as you most likely know, is a very fine lens.
