Thank you
Hello, Thank you both of you. I'd been on Hansen's web site some time ago seeking a formula for Microdol. But I'd forgotten that he also addresses the 120 to 127 problem. He convinces me that it is, as one of you said, not worth the effort. The Vollenda was for nostalgia's sake, the Rollei because I like using Rolleis. In connection with the suggestion that I buy a 120 or 620 camera, I'm well fixed in that area. I've used Rolleis for half a century now, and currently still own two 2.8s, a 3.5 Auto, a Tele, and a Rolleicord II. (I also have a Hasselblad, but find it awkward compared to the Rolleis and use it only when I need extension tubes.) The only problems with Rolleis is that they are definitely NOT pocket cameras!
Thanks again and Happy New Year,
John
