lcd Posted August 13, 2012 Share Posted August 13, 2012 <p>I recently acquired a Semflex Oto II TLR camera. The lens is a "Semmar Paris Anastigmat 75mm 3.5".<br>Is this a three or a four elements lens? I still have to test the camera but I hope this lens can give a Tessar type performance.<br>Thank you.</p><p> </p> Link to comment Share on other sites More sharing options...
JDMvW Posted August 13, 2012 Share Posted August 13, 2012 <p>Luca, downsize your image (700 pixel max dimension) so it will fit in line and then put a title on it so it will display. There's little I can see in your image that requires larger than this:</p><div></div> Link to comment Share on other sites More sharing options...
John Seaman Posted August 13, 2012 Share Posted August 13, 2012 <p>The designation "anastigmat" normally suggests a triplet lens in my experience.</p> Link to comment Share on other sites More sharing options...
lcd Posted August 13, 2012 Author Share Posted August 13, 2012 <p>Thanks JDM, sorry for the large file.<br> John, It's true, Anastigmats are very often triplets. I was hoping this one would be better because mounted on an Automatic TLR, and because of the 3.5 aperture.<br> Any other answer would be appreciated.<br> Thanks.</p> Link to comment Share on other sites More sharing options...
dan_fromm2 Posted August 13, 2012 Share Posted August 13, 2012 <p>You might want to ask here: http://www.collection-appareils.fr/phpBB3/index.php</p> <p>About "Automatic," all it means is that film advance and shutter cocking are linked and that the film stops advancing at the next frame.</p> Link to comment Share on other sites More sharing options...

nicolas_renon Posted August 14, 2012 Share Posted August 14, 2012 <p>I wonder if a good triplet is better than a poor Tessar... Anyway, the triplet gives a triplet type performance and the Tessar gives a Tessar type performance, it is that simple isn't it?</p> Link to comment Share on other sites More sharing options...
