jimsimmons Posted November 24, 2008 Share Posted November 24, 2008 The seller has good photos on the website. http://cgi.ebay.ca/ws/eBayISAPI.dll?ViewItem&ssPageName=STRK:MEWAX:IT&item=250328075705 How much should I worry about these scratches in terms of image quality? Of course they affect resell value, butthat's not something I'm concerned about if the selling price is right. Link to comment Share on other sites More sharing options...
pvp Posted November 24, 2008 Share Posted November 24, 2008 A small scratch like that won't have a major effect on your images. Generally the worst thing that will happen is a very slight reduction in contrast (probably need a densitometer to detect the loss.) You can further minimize the effect of even deep scratches by filling the scratch with black paint or opaque. You'd obviously need a wee tiny paintbrush and steady hands to do that.

franklin_polk Posted November 24, 2008 Share Posted November 24, 2008 They won't show up in the image. The absolute worst under normal situations you'll see is some more flare than usual, but that can easily be avoided by using a shade properly.

frank_menesdorfer Posted November 24, 2008 Share Posted November 24, 2008 I agree with the others above however it's a bit to much for my taste but if it's only the coating than its possible to recoate the lens. Rodenstock will do it for you. Link to comment Share on other sites More sharing options...
dave_s Posted November 24, 2008 Share Posted November 24, 2008 You guys are the experts, but I bet little surface coating marks like that would have no detectable effect at the film gate, except under laboratory conditions. Bid on it and if you win the auction, just use it. The seller (Henry's, Toronto) is incidentally very reliable-- I've been buying stuff from them for over 25 years.

bob_sunley Posted November 24, 2008 Share Posted November 24, 2008 Well if the front of the lens has marks according to the description, why is there damage on the rear element according to the photos? Link to comment Share on other sites More sharing options...
w_t1 Posted November 24, 2008 Share Posted November 24, 2008 yes, the rear element damage caught my eye, too. "AS-IS" cannot be returned! I would rather pay more and be able to return if wasn't satisfied after testing. ala KEH. Tom Link to comment Share on other sites More sharing options...
jimsimmons Posted November 24, 2008 Author Share Posted November 24, 2008 Thanks, gang. I may chance it. I've got a gap between my 55mm Grandagon and 90mm Schneider. Would like to fill with 72mm XL, of course, but at 1/6 the price... Link to comment Share on other sites More sharing options...

barry schmetter Posted November 25, 2008 Share Posted November 25, 2008 I've become an inveterate large format lens bottom feeder and I'd be very surprised if you could demonstrate any of those defects under any condition. I have much much worse lenses that produce perfect negatives. I can appreciate the fact that some photographers demand flawless pristine glass and thank my luck when they sit out and don't bid against me.

frank_menesdorfer Posted November 25, 2008 Share Posted November 25, 2008 Berry, what have you done? "I can appreciate the fact that some photographers demand flawless pristine glass and thank my luck when they sit out and don't bid against me." With this statement got yourself a lots of new competitors and more money to the sellers.LOL.. Link to comment Share on other sites More sharing options...
barry schmetter Posted November 25, 2008 Share Posted November 25, 2008 Errr, what I meant to say is-- once a lens coating is breached, slightly scratched or even excessively dusty, the amount of flare, coma, spherical, and chromatic aberrations will obscure the drop in contrast, acutance and resolution. You get what you pay for--that's what I say. Might as well tape a piece of broken pickle jar to a lensboard, but the pickles only cost $1.89 and you get something to eat. :) Link to comment Share on other sites More sharing options...
david_f._stein Posted November 27, 2008 Share Posted November 27, 2008 It's hard enough living in the real world, let alone this microscope world the world of computers seems to have imposed. Let's do an inspection of Weston's and Adam's lenses, Nadar, Atget, Brady, et al. Link to comment Share on other sites More sharing options...
