Rollei SL 66 Help needed - Extension factors

[Marek Warunkiewicz]

Hi! I just got a Rollei SL66 and really can't make head or tails or anything from their bellows extension charts. Is there anyone out there who knows how to read them? I would truly appreciate the help. For some reasons I just can't quite comprehend what they mean or how to work them.

Hi Marek,

on the "side arm" there are factors printed for the most usual lenses. > means lens in normal, < means retro-position. Then just compensate your exposure with the factors given. There is a scale from 10-50 for the extension in millimeters. From one point on (different for each lens), this number is followed by the compensation factor, which is underlined.
Unfortunately I do not have my camera at hand now, but it should be eg. 0,5 for the 80mm lens at 20mm extension and so on.
Then compensate the exposure: 0,5 is half an f-stop, 1 is a full f-stop and so on...

Hope you enjoy your new camera.

Regards, Benjamin
