Choosing a macro lens...

[idb]

Hi,
I want to upgrade my macro lens from a Pentax DA 35mm, f/2.8 macro Limited to one of the following and I would appreciate any advice/feedback anyone can offer, especially if you use any of these lenses:

Pentax DFA 100mm, f/2.8 macro,
Tamron 90mm,f/2.8 DI macro,
Sigma 70mm, f/2.8 EX DG macro or
Sigma 105mm, f/2.8 EX DG macro.

Thanks.
Ian

They are all well regarded. The pentax 100mm wr has the advantages of being weather sealed as well as having rounded aperture blades for beautiful circular oof area (read: good bokeh). If you plan to shoot in adverse conditions, that can be beneficial.

I have the Sigma 105mm Macro. I find it to be a strong performer of a lens, well made and has the added advantage of sitting outside the range of focal length you were looking at in your other post (17-70). I have no hesitation in recommending it. As to whether it is better than the others mentioned, I can't help...

Thanks Matt. Very nice macro shot, btw.
