Phoenix AF 100-400mm f/4.5-6.7

Minolta 100mm f4 Macro lens This is a good Macro lens. The focal length is a good one; the 100mm gives you a bit more subject distance compared to the 50mm macro lenses. This is a very sharp lens with very little vignetting. It is better than the Minolta MC 100mm f3.5 lens in both these respects (rokkorfiles dot com did a good comparison test). There are two main drawbacks to the lens. First, with an f4 maximum aperture, it is very dark and can be difficult to focus. Secondly, the lens itself only goes to a 1:2 macro ratio, and you've got to attach the 1:1 adapter for true macro shots. I personally use a Kiron 105mm f2.8 macro lens which corrects both of these issues. I haven't shot the two lenses head to head, but I've always been impressed with the optical quality of both. Other competitors include the Tamron adaptall 90mm f2.5 (also has a 1:1 adapter), the Vivitar 100mm f3.5 lenses (a budget option; 1:1 is via a screw-in front filter, and a few others. There really aren't any bad 90-105mm macros, as it is a relatively easy lens to design and construct. Even ones from Panagor and Elicar are reputed to be pretty good.
