| Description - | A larger version of the 2.8/100, this lens was first made as the Meyer Orestor with bright fluting finish and pre-set diaphragm, and a detachable mount which can be exchanged for those to make it fit other 35mm SLR cameras. Its production continued with its name changed to Pentacon, where it acquired all black styling, but retained normal coating. The automatic version started in the black fluting period, where both auto and electric versions were made, and acquired multi-coating one generation further down the line. It was also available in B-mount as the Pentacon Prakticar 2.8/135. |

Waiting for daddy by Christian Maldonado Fisker Additional data: Camera: Praktica LTL 3 Shot on: Agfapan 400 ASA at 1/125 sec with f5.6 Runner by Christian Maldonado Fisker Additional data: Camera: Praktica LTL 3 Shot on: Agfapan 100 at 125 sec with f8 or f11 It's amazing what the contrast on the 135 mm pentacon really is, as well as details and the right blur, it can't get better than this. I developed the negatives in teunal for 6,30 min 21 degrees. Postman reads the address on a letter by Christian Maldonado Fisker Additional data: Camera: Praktica LTL 3 Shot on: Kodak 200 ASA at 125 sec and f4 or 5,6 (not accurate) One day while i was testing the Pentacon lenses i suddenly discovered this postman dressed in red uniform and reading the address carefully. Although the sun was very shiny and strong, the lens still handled the difficult red colour quite fair, I simply like the Pentagon 135 mm much and I will use it more often in the future. For the money spent it's beyond imagination. Muddy Boots by Christian Maldonado Fisker Additional data: Camera: Praktica LTL 3 Shot on: Kodak 200 ASA at 125 sec with f5,6. |
