Would someone explain the differences between all the different Zuiko lenses found on Olympus rangefinder cameras. I believe I understand that the letter corresponds to the number of elements in the lens (D is four while G is 7, right?), but does the larger number of elements mean that it is a higher quality lens and I should expect better performance? I would assume so, but I read a couple of comments about the Olympus 35LC which has a G. Zuiko and the people using the camera described their results as not being as sharp as the F. Zuiko on the 35RD. At the same time, the G. Zuiko on the 35-S is described as being "very high quality". I also realize that just because a lens has more elements doesn't mean it's a better lens, but I wonder how the number of elements in the Olympus line-up in particular relates to the quality of the lens when they're compared to each other. Does anyone know or have any thoughts?
