There's a similar thread to mine, but not exactly the same. I recently bought a Rolleicord III and I'm not able to view accurate focus while I have my glasses on and using the pop up magnifier on the WLF. I'm nearsighted and wear progressive glasses for correction. Anyway, in order to view correct focus with the pop up magnifier I need to take my glasses off. Otherwise everything is blurry from close focus to infinity. I have a few other cameras with WLF's (RB67, Bronica ETR, Yashica Mat 124G), that I don't have this problem with. I'm thinking that perhaps someone put a diopter in the pop up magnifier(?). Or perhaps the Rollei pop up magnifier's act differently than others? If someone has some "insight", your help is appreciated. Also, what do I need to do to correct this? I'd love to be able to use it without taking off and putting back on my glasses.
