|
|
So I'm still waiting for parts to fully assemble my Crntury graphic camera..I bought two lenses one is 101 ektar and a rodenstock 127... and I'm thinking about trying to graft Polaroid 600 somehow on to the back.. my question is can either of those lenses and that Century Graphics cover 7.894cm x 7.68cm image?
I have a graflex 23 that came with it. |

The 101/4.5 Ektar was a standard issue lens for 2x3 Graphics. It is a tessar type that covers at least 110% of its focal length.
The 127 Rodenstock was, like the 127/4.7 Ektar, a tessar type normal lens for 3 1/4 x 4 1/4.
Both lenses should cover your format's 110 mm diagonal. |

Is it possible to calibrate the range finder, on a 2.25" x 3.25" Century Graphic, to a 127mm lens? |

The Century Graphic https://graflex.org/speed-graphic/century-graphic.html has 7 3/4 inch bellows draw.
7.75*25.4=196.85 millimeters max extension.
Lens focus from infinity to their closst focus distance within 1/3 of their focal length. 127/3=42.3mm; 127+42=169mm.
Lens can be up to 3mm either side of their marked focal length so one should be able to squeeze a 127mm onto a Century Graphic. _________________ The best camera ever made is the one that YOU enjoy using and produces the image quality that satifies YOU. |
