But is the magnification improved at all? Otherwise, no benefit seems to me. As a guy who started out with 50mm macros, I can tell you that the extremely close focusing distances achieved were often a real PITA. I much prefer the standoff achieved by longer lenses.
I can think of one exception, though. I own a few Nikkor 55mm macro lenses and one Nikkor 200mm macro. Sadly, no 100mm Nikkors, but I do have 100s in other makes. What I've noticed is, sharpness-wise, there's little difference between a 50mm and a 100mm macro. But there was a rather large difference in sharpness between the 50s and 100s I own and that 200mm Nikkor macro. It isn't exactly soft. It just doesn't have the eye-popping brilliance that the shorter focal lengths have.
Anyway, my advice to Atelier is that he should rest confident in knowing his macro is probably at least as good as a 50mm, and I wouldn't worry about getting a 50mm unless he's just after having the set.

Hello friends,
thank you very much for the welcome votes and the opinions. I have retained the following from your words:
1. Smaller MFD; actually goes from 44cm (2/100mm) to 24cm (2/50mm). Allows greater approximation; more pronounced blur (OOF) on certain occasions (Macro or Normal).
2. Wider angle for normal (and maybe macro) photography.
3. It's a great standard lens, in addition to macro.
I would add: a smaller lens (despite stretching when focusing) and lighter.
In terms of performance, sharpness, etc, they should be similar. |
