Hi there,
I will get a 38mm lens for my Diana+ in a couple of days and can't find any infos about the the effective apertures. They are said to be 11, 16, 22 and 150 for the regular 75 mm lens. Would the apertures for the wide lens calculate as 5.6, 8, 11 and 75 since 38 mm is about 1/2 of 75 mm? It surely would if the aperture would be in the focal distance plane, but it is much nearer to the body. Any experiances or thoughts?
