I will admit it is confusing. It also won't work if you try to use AF. If you switch it to 1:1 and try to use AF it will probably kick back out to the next magnification level. You need to switch to MF. Other than this it is a very nice lens.

Why do you say AF won't work at 1:1?

It doesn't for me. I read somewhere the technical reason AF is problematic at 1:1 but i can't remember it. I think that is one reason why most people seem to use MF at 1:1 macro. Maybe the other reason being to get the proper focus on a thin DOF, MF is better. I don't know if it is peculiar to this lens, I only have used the 60mm for macro work.

I don't disagree with the practice of using MF for macro work. Given the extremely thin depth of field when shooting insects, MF is a more precise method and is in fact what the "real" macro photographers over on the Macro and Still Life forum prefer. I was just asking if you had found that AF physically would not function with your lens, as opposed to not delivering optimum results.

I tried mine before making my other post. I set my lens to 1:1; it dropped back to the .19 - .4 meter mark as expected. I then got about 5-6" from an object (a toenail clipper if you must know, nothing artsy about me!!), and the AF seemed to work OK. In fact, at 6" handheld, I could not tell the difference between AF and MF images. When I put the lens to within maybe 4" of the object, it focused but not as quickly. At 2-3" it was definitely having trouble with AF. Of course, the lower level of lighting indoors in my bedroom may have contributed to this; outdoors on a sunny day taking photos of a multicolored butterfly might be better. (Of course, getting closer than 6 inches to a bug presents a different set of problems, in that they are likely to become spooked and fly off.)

Anyway, from my limited tests AF does work; it's just that the closer you get (6" or less), using MF will give better results.

That's interesting, I find it just doen't work on my copy and if I try to use it I lose 1:1.  Perhaps it is operator error or maybe this only happens in bad light.
