craigd Posted August 11, 2010 Share Posted August 11, 2010 <p>There's the Voigtlander Normal 40mm f/2 SL Manual Focus Lens for Universal Screw Mount (Pentax M42):</p> <p><a href="http://www.bhphotovideo.com/c/product/363161-REG/Voigtlander_45BA229APE_40mm_f_2_SL_Manual.html">http://www.bhphotovideo.com/c/product/363161-REG/Voigtlander_45BA229APE_40mm_f_2_SL_Manual.html</a></p> <p>But realistically, can't you use a 35mm lens instead?</p> Link to comment Share on other sites More sharing options...
paul_wheatland Posted August 11, 2010 Share Posted August 11, 2010 <p>I had one, it was German, very slow f4.5, pre set, ideal for DSLR but maybe not for the speed? I don't remember the make but it definitely was German, try ISCO, Steinheil, etc.</p> Link to comment Share on other sites More sharing options...
JDMvW Posted August 11, 2010 Share Posted August 11, 2010 <p>Do like your M42 40mm. I generally prefer a <a href="http://www.historylink101.com/ww2-planes/browning-machinegun.htm">Browning 50mm</a>, myself.</p> <p>If you were not just looking for an excuse to post, I do have a former web page on M42 lenses in pdf format.</p> Link to comment Share on other sites More sharing options...

craigd Posted August 11, 2010 Share Posted August 11, 2010 <p>True, but you can find these lenses on eBay if you want one.</p> Link to comment Share on other sites More sharing options...
john_fleetwood Posted August 11, 2010 Author Share Posted August 11, 2010 <p>No, I really like 40s. I've got a 40/2 Zuiko on my OM1, an Oly 35 RC with a 42/2.8, and my EF 28/2.8 is a 45 equivalent on my Canon 30D. I'd like a 40 to put on my M3 of SLRs, the Pentax SL.</p> Link to comment Share on other sites More sharing options...

Mike Gammill Posted August 11, 2010 Share Posted August 11, 2010 During the 50's there were two Kilfitt 40mm lenses (one to 1:2 and another focusing to 1:4). I know you could get them in Exacta mount but don't know about M42. Link to comment Share on other sites More sharing options...
craigd Posted August 11, 2010 Share Posted August 11, 2010 <p>Here's a Carl Zeiss Jena 40mm f/4.5 lens for M42 currently being offered on eBay:</p> <p><a href="http://cgi.ebay.com/Carl-Zeiss-f-M42-4-5-40mm-Tessar-T-/370411684880?pt=Film_Cameras">(LINK)</a></p> <p>I'm not familiar with the seller. 98.2% positive feedback strikes me as on the low side; I usually buy from 99%+ users. Not a lot of info about the lens, either. Still, it's an interesting data point.</p> Link to comment Share on other sites More sharing options...
john_fleetwood Posted August 11, 2010 Author Share Posted August 11, 2010 <p>Wow, f4.5, that's pretty slow. Nice looking lens, though.</p> Link to comment Share on other sites More sharing options...
tommyinca Posted August 11, 2010 Share Posted August 11, 2010 <p>The Zeiss Jena 40/4.5 was the first wide angle lens for SLR in M42 mount. Normal lens was 58mm at the time. The other Kilfitt 40mm/2.8 also available in M42 mount is a macro lens by Heinz. One version is a 1:1 Makro, the other 1:2. </p> Link to comment Share on other sites More sharing options...

fred_c1 Posted August 12, 2010 Share Posted August 12, 2010 <p>If you cannot stand to see "35mm" on the front ring, here's an idea: sell the Pentax and get a Konica SLR with a 40mm lens.</p> Link to comment Share on other sites More sharing options...
john_fleetwood Posted August 12, 2010 Author Share Posted August 12, 2010 <p>Fred, I've got no problem with 35s. Or 50s, 28s, 105s, or any other lens.</p><div></div> Link to comment Share on other sites More sharing options...

ric_carter1 Posted April 14, 2011 Share Posted April 14, 2011 <p>Regrets that I found this thread so late. Just three hours ago, from a local antique shop I purchased an Exakta VX with Makro-Kilar E 50/3.5 (1:2) for US$72.25 total. I am happy. It joins my other Forty, a tiny pancake Meyer Helioplan 40/4.5 which a few months ago on eBay cost me US$12.55 shipped.</p> <p>These are both in Exakta mount. Both are reputedly available in M42, but I have not seen those. I shoot Pentax (d)SLRs. I have devised a simple, non-destructive, totally reversible adaptation of Exakta to Pentax K-mount (PK). Use contact cement to glue an M39-M42 adapter ring around the Exakta bayonet. Use rough sandpaper to grind about 0.7mm from the flange of a cheap clone M42-PK adapter. Mount lens on PK camera; if infinity focus is not achieved, grind the PK adapter a bit more. To reverse the adaptation, use thinner to dissolve the glue and put the lens back in its original state.</p> <p>I have so adapted a number of Exakta-mount lenses, and enjoy their use. For M42 use, just omit the PK adapter, but infinity focus might not be achievable. With the Makro-Kilar, that hardly matters, now does it?</p> <p>As for what constitutes a Forty: If we allow 10% tolerance, then the range is 36-44mm and so includes the Mir-1 37/2.8 but not the Chinon 45/2.8. Yes, many rangefinder Forties exist, but those are rather difficult to adapt to dSLRs except for close-up use. Oh no, not ANOTHER macro lens!</p> Link to comment Share on other sites More sharing options...
