Sigma 105mm f/2.8 1:1 Macro EX DG On Tree

2009-05-08

After I sold my Tamron 90mm f/2.8 1:1 non-Di Macro, I am now down to 1 macro lens that does 1:1. The Tamron is just as decent as Sigma but I finally pick the Sigma to stay as I have Pentax FA 77mm f/1.8 that is closer in focal range to the Tamron 90mm. Had I not had Pentax FA 77mm f/1.8, I would have picked the Tamron to stay for the dual purpose lens for macro and occasionaly portrait lens.

I compared the two macro lens on both flowers and portraits, both do well in my book neck to neck for performance, value, and ease of use. I prefer both Macro lens over my experience with Lester A Dine 105mm f/2.8 1:1 Dental Macro. The Lester has better color but I find both the Tamron and Sigma serving me better with AF and the addition of focus limiter making the macro lens well rounded lens for both macro shots as well as for portraits, street shooting and candid shots.

I took out my Sigma this morning shooting out on trees with interesting bark and tree sap. The Sigma has beautiful bokeh and color. I find a tendency of underexposure again but it is all good in my book with +0.3 Ev.

Impressions & Notes

  • I prefer Sigma and Tamron macro over the old faithful in Lester A Dine 105mm f/2.8 1:1 Dental Macro.
  • Though the Lester A Dine has better color, I don't favor the lens due to absense of focus limiter and the difficulty to achieve 1:1 with long focus throw. Perhaps, a good macro and lighting set up would have altered my not-so-impressive experience before with Lester A Dine
  • I picked Sigma over Tamron solely based on my focal range too close to FA 77mm
  • The Sigma and Tamron will be toss for me, I can take any one and I will be just as happy
  • Sigma has a tendency of underexposure with Pentax K20D.

How would you compare 105mm with FA 77mm. I can only buy one and I am getting 105mm for just USD 300, pls suggest

@Antoni, the 105mm is a totally different lens than the 77mm limited. In digital, it is a big long for protraits. If you can only buy one and that you need a macro lens, stick with 105mm for its true 1:1 macro lens ability. If you are in the market for a good portrait lens, you can also consider the Tamron 90mm f/2.8 1:1 Macro that is closer in focal length. Another great macro lens that I wll recommend. Also, the DA 70mm f/2.4 is a superb limited lens that does extremely well in portrait and oost much less than the 77mm.
