Originally posted by yeatzee I could have (and just might!) sworn/swear it was a reversed 35mm they equated it to. Plus isn't the focal length never actually what it says when you get into 1:1+? (or am i just going crazy lately?
I need to study reversed optics a bit, find out what's going on there. Meanwhile, about insanity: Much is possible. A basic finding of physics is, "Anything that can happen, WILL happen, eventually".
Oh yeah, +1 awesome photo!
Originally posted by MegaPower but why it would be better to use a 35mm macro instead of longer macro (let's say 100mm)?
Is it diffraction?
No, not diffraction, just convenience. For similar magnification, a longer lens needs MUCH more extension. And to reach 5:1 we want the shortest focal length feasible, to keep the total rig from being very bulky.
