You can set the Kalart, which is what I have on mine, to different focal lengths, but you only want to do it one time. I say that because it's really hard to adjust it at all distances after that. So I set mine for 135mm as my standard lens and use the ground glass or guess focus for the 100mm Wide-Field Ektar and 210mm Fuji. I get by just fine this way. Cams are nice, but not so nice when you lose them.Can the rangefinder on the Busch Pressman/Sears Tower Press be adjusted for different focal length lenses, or are you "stuck" with the 135 mm focal length if you want to use the rangefinder?
