The Diopter Thread. In: Cameras Posted February 17, 2016 36 minutes ago, Lavanboy said: Would you be interested in selling the diopter? I'm holding on to it for now... I should start using my gear again sometime I do have some diopters I'm willing to part with. Like the Tamron +0.5 diopter (72mm close up adapter lens for 28-200mm) It's not an achromat, but it's cheap and works quite ok. You can find plenty of info on the anamorphic forum here. I do have some smaller achromats. Not sure if useful but if anyone is interested, send me a message: Minolta Close-Up Lens No. 0. 55mm - diopter +1 Leitz Elpro VIIb 54mm (weird size) - diopter +0.75 (?) Minolta Close-Up Lens for Autopak-8 67mm - diopter +2.5, or +3 according to http://www.ki.tng.de/~sgude/achromats.html?
