These were engraved "Post", or "DBP", or "Image subject ratio 1:8", or nothing at all.  </p> <p><strong>Features of the 35mm Summaron f/2.8</strong></p> <ul> <li>Clip-on lens hood</li> <li><span>Optical lens/groups 6/4</span></li> <li><span>Close focus Screw/M-mount 0.65/1m</span></li> <li>10 blade aperture</li> <li>39 mm filter mount</li> <li>Length 35.77 mm overall</li> </ul> <p><strong>Item Specifics</strong></p> <p><strong>Leica product code</strong><br>-<span>SIMOO/1106 Screw mount</span><br>-SIMOW/11106 M-mount<br>-SIMOM/11306 M-mount other cameras</p> <p>S/N 1947855</p> <p>This lens would be a great addition to your M system, if not to use on your M, but to have in your Leica collection (manufactured in 1962). The lens is very clean but shows signs of normal use. The drag is smooth with focusing. The aperture has good feeling with positive detents. The glass elements are clean. Service has been completed recently by Leica. The work performed was to clean, lubricate, and adjust all parts for proper working condition. Overall, this lens is in excellent condition. </p> <p><strong>Item Includes</strong></p> <p>The 35mm Summaron lens with the front and rear protective caps.</p> <p><strong>Warranty</strong></p> <p>Leica 1 Year Warranty</p> </div> <a href="#" class="more">Read more...</a> </li> <li id="tab2"> <p><strong>Leica product code</strong><br>-<span>SIMOO/1106 Screw mount</span><br>-SIMOW/11106 M-mount<br>-SIMOM/11306 M-mount other cameras</p> <p><meta charset="utf-8">S/N 1947855</p> <p><meta charset="utf-8">This lens would be a great addition to your M system, if not to use on your M, but to have in your Leica collection (manufactured in 1962).
