I think I can complete Pieter's post on at least 1 point: the Zeiss-Ikon lens he refers to is the Zeiss-Ikon T* Sonnar 90mm f2.5, considered at the time (around 10 year ago) as the best flatfield projection lens on the market (note the T* coating and the Sonnar name from Carl Zeiss fame). It was sold through the Braun Paximat catalogue. I personnaly use that very lens on my Pradovit 600 with very good results, though it seems just a little too thin for the thread. It is a beautiful, metal barreled lens. To go back to one of your other mails: you state you use the Colorplan CF for plastic mounted slides and that you get center-to-corner sharpness. I use the Super-Paxon 85mm f2.5 CF, but it does not really help me with those glassless mounts. The Pradovit 600 still provokes slide "popping" (after around 5 seconds on a room temperature slide) and neither the flatfield nor the curved field lenses I have respond properly to that. So, before investing into a Colorplan CF, I would like you to confirm the following points: do your plastic mounted slides "pop" when projected through your Pradovit 600 ? Does your CF lens manage sharpness on the whole field AFTER the "pop" occurs or before it occurs ? Thanks beforehand for your answer Friendly regards Alan Brussels-Belgium Nathan Wajsman wrote: > Below is a message I received from Pieter Krigee at Foto Nivo-Schweitzer in > Amsterdam, explaining some of the differences between the Pradovit 150 and 600 > and giving some of their origins.
