OlDoinyo Posted December 3, 2016 Share Posted December 3, 2016 Going for 19 euros? I'll bet it will go higher before the end. That looks like the version with a proper filter thread (but I may be mistaken there.) Link to comment
Alex H Posted December 4, 2016 Share Posted December 4, 2016 I have had several 50mm Cassar and Cassar-S, as well as 40mm Cassaron, and still have some. They all are very prone to getting scratches on front and rear element. Link to comment
Andy Perrin Posted December 4, 2016 Share Posted December 4, 2016 I put in a bid. :-) I don't have very many lenses yet. Does anyone know of a very fast uncoated lens? I'm looking for my SWIR experiments. At the moment signal-to-noise ratio is awful, with almost 0 contrast, so I'm trying to improve the "signal" part. Link to comment
Andrea B. Posted December 6, 2016 Author Share Posted December 6, 2016 You don't really need a lot of lenses.But you might want to start slowly saving up for a CO60? If after a couple of years of saving you find your interest has waned, you can instead take a nice vacation to Hawaii instead of buying the lens. :lol: Link to comment
Andy Perrin Posted December 6, 2016 Share Posted December 6, 2016 Heh, well, let's say I would like some GOOD lenses. What I have are two crappy lenses and the Novoflex Noflexar, which is my favorite. I realize different people like different attributes in lenses, but I really dislike soft images. Link to comment
Andrea B. Posted December 6, 2016 Author Share Posted December 6, 2016 You'll get there!! I have been meaning to try to determine how much "softening" (apparent or real) might occur because of lack of chromatic aberration corrections. I ran a couple of aluminum foil tests and definitely could see color fringes with one of the UV-capable lenses compared to the UV-Nikkor. But I never found time to run the shots through a good edit. Guess I'd better go add this to the Experiment List which I have around here somewher.e Link to comment
rfcurry Posted December 7, 2016 Share Posted December 7, 2016 Andy, What is the camera you are using for your lenses? IOW, are the mount and flange-film distance restrictive in terms of lenses?Thanks. Link to comment
Andy Perrin Posted December 7, 2016 Share Posted December 7, 2016 I'm using a Sony NEX-7, which is mirrorless so I don't think there is much restriction. So far I have found adaptors for nearly every kind of mount. Link to comment
rfcurry Posted December 7, 2016 Share Posted December 7, 2016 I wasn't worried about the mirror so much as the ability to focus to infinity.Andy, you might find lenses made in Germany pre-1971 to be both inexpensive and high quality. However, you want 1/ speed, 2/ sharp images, and 3/ low cost. The old adage applies, you can usually get only two out of three. :) For example, cine lenses will give speed and low cost; but they will probably cause vignetting due to the small 16mm film size. OTOH, if you look at something like #291961006392 on ebay. It is a Rollei Schneider 50mm f1.8 SL-Xenon for Rolleiflex SL35. Schneider-Kreuznach made many fine lenses. The Xenon is a 6 element/four group design that is said to be sharp -- http://allphotolenses.com/lenses/item/c_3113.html With only four groups it should be decent in the UV. It also, IIRC, predates multi-coating on Rollei. I have some duplicates in longer lenses by Piesker, but they are triplets, so not as sharp as you want. Send me a message if you think of a piece of German glass you want, and if I have one, it is yours for a small sum. I am feeling very guilty about lens clutter. Link to comment
Andy Perrin Posted December 8, 2016 Share Posted December 8, 2016 Thanks, Reed, I'll keep that in mind! I need to decide on what I want first, and what I want to shoot also, which directly impacts the former. :-) Link to comment
Hornblende Posted January 16, 2018 Share Posted January 16, 2018 There is a UV-Sonnar on Ebay right now: https://www.ebay.com/itm/ZEISS-Hasselblad-Sonnar-UV-f-4-3-105-mm-CF-IR-PhaseOne-UV-ACHROMATIC-lens/282479853872?hash=item41c51c8130:g:FhAAAOSww9xZGkea At that price I could buy 6 UV-Nikkor 105mm Link to comment
JMC Posted January 16, 2018 Share Posted January 16, 2018 There is a UV-Sonnar on Ebay right now: https://www.ebay.com...hAAAOSww9xZGkea At that price I could buy 6 UV-Nikkor 105mm That ones been on there a while, going up and down in price. Seems to be a bit higher than going rate at the moment. Link to comment
Andrea B. Posted January 20, 2018 Author Share Posted January 20, 2018 IMHO, that UV-Sonnar is vastly overpriced. But hey what do I know?? :rolleyes: Link to comment
