Pentax DFA100/2.8 macro vs Sigma EX 105/2.8 macro

I would be interested in a macro lens for the K10D. Both the Pentax DFA100/2.8 and the Sigma EX DG 105/2.8 are about the same price (at least here in Switzerland).

Any experience to share about these lenses? Which lens is better?

I have owned the Pentax DFA 100 for about 3 weeks and like what I have seen from it on my K10d. Pictures are very sharp with good color. It balances nicely on teh K10d. I have not tried any Macro shots yet.
I do not have any experience with the Sigma.
Here is a link to a photographer who really likes the pentax DFA 100 and has posted pictures taken with the lens. Sort by Lenses Photo Gallery by alinla at pbase.com

Best Wishes,
Erl

From what I had read and found so far on line, Sigma 105mm macro has a better centre sharpness than Pentax DFA 100mm macro (in relative terms). This is really not a big deal as many people do not take macro shots wide open and most people are more concerned about bokeh quality and colour rendition.

Sigma is bigger and more solid build than Pentax; Sigma is also heavier as well. Sigma does enhance colour better by a built in strong UV filters in all the EX series - hence colour is richer rather than washed out.

In most on line reviews and magazine publications reviewing the macro lenses, sigma and pentax were not really not the hot favorite (I am a reborn pentax fanboy though)

I would go for pentax if the cost difference between these two brands is little in your country. Pentax is smaller, more compact, delivering fantastic colour and bokeh; afterall, it is pentax we are talking about.

I am waiting for my own macro as well.


Good luck
