Is the "3D effect" as easily obtainable on the Pentax 67 line of lenses. Not to be confused with "bokeh" http://photo.net/leica-rangefinders-forum/008vML OK well, I don't mean that it is "easy" because it requires good technique, lighting, composition, etc. but I've also heard that it is most pronounced with German glass because of their high micro-contrast. I've seen this moreso on small format cameras but that's probably because of popularity. I'm interested in the 67, but since it is medium format, you have more negative to work so this effect should still be obtainable given the same circumstances. I know that these are two different system/formats/lenses but i'm curious in this one particular aspect.
