matt_mitchell Posted September 10, 2011 Share Posted September 10, 2011 <p>Hi,<br> I found this Chinon CEII memotron for sale which I wanted to use with my Pentax 50mm 1.8 takuma. Couldn´t see what lens it had on it in the photo where it was posted for sale. Anyway it happened to come with an Auto Chinon 1:1.2 Tomioka lens. No scratches or problems internally with the glass but as seen in the photos part of the rear glass has broken off.<br> One of the photos shows the lens fully open aperture through the back of the camera, where the fault can be seen at the bottom. (However, looking at the top you can see the top line of the camara body also cuts out the top edge part of the lens which is normal)<br> My question is will this affect the photos at open or other aperture? I am going to try it of course but I was hoping someone with more experience could tell me. <br> Also any other info about the lens?<br> The camera and lens cost me $20 by the way.</p> <div></div> Link to comment Share on other sites More sharing options...

Philipp500 Posted September 10, 2011 Share Posted September 10, 2011 <p>I don't know this specific camera and lens combo, and it is not very clear where you see broken off glass. It may be that the lens' speed is more than what the camera has been designed for and that the lens has been build with that protruding thing to make it as round as possible wide open. At F 1,8 or F 2 it should look perfectly circular. <br> The Hexanon 57 F1,2 had a similar problem. It doesn't affect picture quality at all.<br> Should you not like that lens, please let me know, I'd be delighted to buy it from you if the price is right!</p> Link to comment Share on other sites More sharing options...
matt_mitchell Posted September 10, 2011 Author Share Posted September 10, 2011 <p>If you look at the photo of the back of the lens it is pretty clear near the aperture pin the glass is not rounded, it almost looks like it is meant to be like that,.... or thinking about it, is it actually meant to be like that?? I thought the glass should be a perfect circle?? If it was made like that then I am an idt, a very happy one tho lol!</p> Link to comment Share on other sites More sharing options...

JDMvW Posted September 10, 2011 Share Posted September 10, 2011 <p>No half-way decent f/1.2 lens is ever that cheap!</p> <p>Fascinating. Hope you'll show of some pictures taken with it.</p> <p>You know, it was Chinon that got Butkus started on collecting old manuals. ;)</p> Link to comment Share on other sites More sharing options...
rick_drawbridge Posted September 10, 2011 Share Posted September 10, 2011 <p>Ooooh! 'Tis indeed meant to be like that... A very great score, <strong>Matt</strong>; I've seen the lens on auction sites with "Buy Nows" in excess of $800, but I don't have any recent sale figures. They're very definitely sought-after. Some people have all the luck...</p> Link to comment Share on other sites More sharing options...
fred_c1 Posted September 10, 2011 Share Posted September 10, 2011 <p>Your real problem is the fingerprint on the glass. But I'll pay you $50 to rid you of the imperfectly shaped lens.</p> Link to comment Share on other sites More sharing options...
matt_mitchell Posted September 10, 2011 Author Share Posted September 10, 2011 <p>This is the second time I have picked up something special cheap here in Quito, Ecuador. I bought a perfect condition 55mm 1:1.2 olympus zuiko for $30 at an old photography shop, the saleman wrote on the receipt "Olympus 55mm 1.2 normal lens $30" !<br> This Chinon lens really is in excellent condition except for the small fingerprint mark you can see which I assure you wasn´t me.</p> Link to comment Share on other sites More sharing options...
jay_de_fehr Posted September 10, 2011 Share Posted September 10, 2011 <p>I paid $10 for my Minolta XD11 w/ 58mm f/1.2, at a local thrift store. I can still remember how my heart rate soared when I found it! Congratulations, and use it in good health.</p> Link to comment Share on other sites More sharing options...
tony_lockerbie Posted September 10, 2011 Share Posted September 10, 2011 <p>The Tomioka fast lenses have garnered a fair bit of collector interest and the prices are very high these days. Some folks use them on their Digis, and like the soft effect that they give when used wide open. I've never seen one for $800.00, but I rekon that around $400.00 is what they seem to go for, anyway you got a really good deal!</p> Link to comment Share on other sites More sharing options...
matt_mitchell Posted September 10, 2011 Author Share Posted September 10, 2011 <p>Thanks for the info, on ebay there is one the same advertised buy it now at $864.98<br> http://www.ebay.com/itm/160646464855?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649<br> and a yashica yashinon version on auction at the moment it is at $415 with a few bids<br> http://www.ebay.com/itm/250886803631?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649</p> Link to comment Share on other sites More sharing options...
tommyinca Posted September 11, 2011 Share Posted September 11, 2011 <p>This is normal for this lens. Look at it from the plus side, it cost much extra to cut the rear elements like that. If you ever look at the back side of a Canon EF85/1.2, it is also not circular due to the electrical contacts blocking part of the real element. </p> Link to comment Share on other sites More sharing options...
winfried_buechsenschuetz1 Posted September 16, 2011 Share Posted September 16, 2011 <p>There seems to be a hype around Tomioka fast lenses - or, to be more precise around ALL japanese fast lenses whatever brandname they bear and whether they are actually made by Tomioka or not. Sellers even try to sell retailer-branded lenses with f/1.2 and f/1.4 for hundreds of EUR on german ebay. So it seems I was quite lucky to find a Revuenon f/1.4 55mm lens with damaged (and repairable) filter thread on a local flea market for just 10 EUR two years ago.<br> So maybe you could sell just the lens for 10 times the price you paid for the combo :-)</p> Link to comment Share on other sites More sharing options...
