The focusing direction is not the same as in Pentax lenses but IMO this is not very important in a macro lens. When shooting macro you have to use manual focus - AF tends to hunt annoyingly - which requires you to switch both the lens and the body to manual. But I guess it�s the same with Pentax lenses. > > Build quality is excellent and so is picture quality.

I almost always use manual focus with the Pentax 100/2.8 Macro. No wussie clamp either for those not used to the ease of focus :-). Anyhow, AF does seems to be quite good anyhow. And it's not true, you only must turn off AF on either the lens or the body. And the clamp is there if ya want ;-) I don't get it, all these people saying Sigma, when normally everyone here is scared of digital and k-mount and in into Pentax 'for the glass'. Odd. And the 5mm is nothing. Brad
