About your original question about adapting Rollei 6000 lenses, nobody makes adapters that can actuate the aperture.
Fotodiox makes the adapter with a behind the lens aperture, you can stop down 1, maybe 2 stops before hard vignetting sets in but effectively you use the lenses wide-open only.
I have one here and tried all my lenses with it, and just for posterity's sake:
All tried with a Panasonic S1 (35mm sensor) and the following lenses.
HFT 50/4 -> Reasonably sharp, nothing special but not a useful combination.
PQS 50/2.8 -> Surprisingly very sharp all over the frame, but this combination is massive, not useful.
PQ 80/2 -> Reasonably sharp, but not very. Again too chunky for what it is, a plain Nikon AI 85 is more practical.
PQS 80/2.8 -> Quite sharp, reasonably sized.
PQS 150/4 -> Sharp, reasonably sized, could be useful.
PQ 180/2.8 -> A bit softer then the 150, wide open a great portrait lens, but its absolutely massive.
HFT 250/5.6 -> Sharp, could consider as a relatively compact long tele.
Conclusion; If you already have the lenses there can be some use to it and only really in the portrait-tele's range.
I paid 50 euro's for my adapter and already own the lenses, given the above findings the only Rollei lens i plan to use this way is the 180mm.
Otherwise a set of cheap adapted Nikon AI lenses would make more sense.
