Just got myself a nice Mamiya C330f with a 80mm F2.8 black Mamiya Seko lens but
I'm planning to get one or 2 more lenses (65mm and 135/or/150mm) to complete things
up but I wonder if an older chrome 65mm lens with the Seikosha-S shutter will work
with the C330f body: will it fool the auto-cocking mechanism on the body as I believe that
it is manually cocked. With the C330f am I limited to the 'newer' black lens?
Seikosha-S shutters: Yes (except early 180mm - try before you buy)
Seiko (black) shutters: Yes
There have been a few instances of camera bodies not moving the shutter cocking levers correctly on compatible pairings, but that is an adjustment issue.
I had a slight problem using a chrome lens on the C330f. As noted in a previous post, it could be remedied by adjusting the linkage - but that made it difficult to switch lenses. I found a solution by putting a short (about 1/4") piece of aquarium air tubing on the shutter release lever of the lens.
