Vallo, there are better lenses. The shorter the MP-4 Tominon, the better. I wouldn't use a 75 (n = 3) and the 135 is dreadful (n = 3). Sorry, never had a 105.
MP-4 Tominons' recommended magnifications, from MP-4 documentation
focal length (min magnification to cover 4x5) recommended magnifications type
135 mm 1x - 3x Tessar
105 mm 1x - 4x Tessar
75 mm (2x) 2x - 6.5x reversed Tessar
50 mm (2x) 2x - 9.8x 6 group symmetric triplet (sic)
35 mm (5x) 5x - 14x reversed Tessar
17 mm (10x) 10x - 32x 6 element 4 group
From 2:1 to at least 5:1 there's little that will beat a reversed 55 Micro Nikkor. My 55/2.8 is best at f/4, visibly loses central image quality at f/2.8 and f/5.6. In discussions of 55 MicroNikkors on the French LF forum, one poster said he'd tested an f/3.5er against and f/2.8er and that the f/3.5er (sorry, don't know which vintage or which aperture(s) he tested at) and found the f/3.5er better.
But since Barry the vague hasn't told us enough about what he's trying to accomplish its hard to tell whether any of the advice he's been given (except mine, to look up Ray Parkhurst if he's going to shoot coins).
Barry, here's another piece of advice. Before you go shopping for anything, buy a copy of Lester Lefkowitz' book The Manual of Closeup Photography and, if you're going to work above 1:1, a copy of Brian Bracegirdle's book Scientific Photomacrography. Both cover the same ground, the repetition will be good for you. Bracegirdle's discussion of which lenses is strongly biased towards lenses from microscope manufacturers and microscope divisions of merchant lens makers such as Nikon and Zeiss.
Peter, macro is macro regardless of how the image is captured. Its been a while since Ray and I have communicated, but I believe he's used film. He really does understand what he's doing and Barry should find what he knows about lighting very useful. In real life Barry is a sort of cabinet maker and his products are, like coins, quite reflective.
