I have a set of OPTON S16 lenses. They're equipped with RAF-camera ARRI B - PL adapters. Now, 1,5 years after previous service, the 9.5mm and 12mm won't reach infinity anymore. So I'm going to get the whole set serviced but I was wondering if someone somewhere can convert the whole set to PL? And is there someone here that could share some experience using these lenses with high quality adapters VS permanent PL conversion? Is there any real advantage or down sides to conversion? It it even possible? One option might also be to get them rehoused - has anyone done that?

OK, I guess these are then MK1 since they all had different fronts, small "rabbit ears" to control focus and ARRI-B mounts before I got them fitted with 80mm fronts, PL-mounts and gears.

Thanks for quick responses! The lenses I bought have a regular iris. So which generation are they comparable with?

Hi all, I just purchased a set of Oberkochen Opton S16 lenses, all T1.3. Body says: Made in West Germany. From the looks of them, it seems almost like they were never actually used. Now, I can't find any information about these lenses online or how they differ from their newer siblings - or are they even regarded as Zeiss? Furthermore, the set has 9,5mm, 12mm, 16mm and 25mm but is there also a wider than 9,5mm or longer, like a 50mm lens, to be found from that same generation? Thanks in advance, Theo
