I know I can combine a macro lenses with teleconverters and extension tubes however I'm trying to get a grip on how this affects things.
Putting a 2x teleconverter on a 105 mm lens gives me a 210 mm focal length, however, does it affect my magnification (i.e. change my 1:1)?
Also, I think I understand if I put an extension tube on a macro lens I increased my magnification. Therefore if I put a 105 mm extension tube (105 mm for the sake of discussion) I end up with a 2:1 magnification, right? Does my focal length change or stay at 105 mm?
Does this also mean that extension tubes of the same size would give more magnification to a shorter, 60mm, macro lens than a 105 mm macro lens? I was under the impression that extension tubes work better on longer focal lengths or is that just because of the working distance?
Thanks, Ralph
