Originally posted by ivanvernon Thank you Paolo. I have followed your work and other postings and comments also, and have benefited from them so I am very honored to have you notice what I am doing. Yes, I am trying to obtain the best quality of the CZJ lenses, and also have on order several others that ought to get here in a week or so.
It is winter time here, with plenty of snow, so a little difficult to find good subjects for test shots, but I keep trying with the Sonnar, and will do so with the others as they arrive--the Arsat 30mm 3.5 fisheye and the CZJ Biometar 120mm f 2.8.
When all the lenses are in hand, I will run some film either in 135 or 645 format. I have sort of gotten away from 120 film because of the expense and inconvenience of development, but feel a little guilty about it.
Take care, and know that I will treasure your future comments that I am sure I can learn from.
Thanks.
I try to be useful, though I confess that many info, and most of the wisdom, come from a "master of old cameras" friend who has plenty of first-hand experience about vintage photographic equipments.
He is the same person who converted long time ago some of my Pentacon Six stuff to Pentax 6x7 mount.
He did the Pentacon 500mm and the bellows, the Arsat fisheye required plenty of work/time, so I stopped the program, sold the Pentacon Six, the Arsat, a brand new Kiev with the 80mm Vega, and the Flektogon 50mm.
I kept the two Biometars and a couple of other lenses for 35mm and digital use.
I intended to use the Biometar 80mm with a tilt adapter... that I never purchased
I still have the shift adapter I bought for the Arsat... but it didn't work as intended because defishing at that time didn't work well for architecture (not sure it could, even now).
I even sold and later re-bought a couple of them. I had the all-black late MC versions, and now I have the older ones.
The fellow who did, and still does, my conversions has two lathes, a micrometric burr, and an amazing amount of experience/knowledge of old cameras, and is a very competent collector of stereo cameras. He also owns plenty of old Leitz projectors... which of course have no use with stereo pictures. Quite odd
I remember I brought him a 6x7 macro tube to rip off the bayonet and use it to convert the Pentacon 500mm. When I got back the lens I found that the tube was still whole, and the bayonet had been painstakingly machined anew at the lathe.
He didn't want to ruin an original Pentax extension tube...
When I'm at a loss, he is the source of practical no-nonsense advice.
I am honored to share in another language/context some of the little bits of knowledge he passed on to me.
Cheers
Paolo
