What happened in the last month? Amongst others, I completed a quarter of the business internship to which I’m obliged by University regulations. The two weeks at Fotohaus Zacharias (DEZ/Regensburg) were very pleasant, varied and informative… If you need expert advice in the field of digital cameras and photography in general, Fotohaus Zacharias is definitely the place to go. And I was not paid for that statement.
Speaking of photography… I pursued a new lens: the Sigma 70-300mm f/4-5.6 APO DG MACRO. On the left hand side, it’s at 70mm, on the right hand side, at 300mm in Macro mode (both photos have been taken fairly quickly and sloppily)… Although I am satisfied with my Hanimex 72-162mm f/3.5 Macro (M42), I’ve realised that portrait and people situations are handled more easily with an auto-focus lens. I informed myself thoroughly about the Sigma and its equivalent, the Tamron 70-300mm f/4-5.6 DI MACRO. The internet revealed the following (and questionable) tendencies:
- Sigma: faster AF, high rate of quality defects, poorer image quality, higher price
- Tamron: slow AF, better sharpness, heavy chromatic aberrations, at a more favourable price
I have never had any complaints about the image quality of Sigma lenses, yet had experienced the heavy CAs with my brother’s Tamron. Just like Faust, I was no wiser than I was before. But instead of being visited by a devilish poodle, I had the opportunity to borrow and test both lenses. This is not supposed to be a review, but in a number of 23 different apature settings, I could compare the contestants’ image quality efficiently… The score: Sigma 14, Tamron 4, draw 5. The Sigma stood out as a clear winner, as the image quality was significantly better in comparison. Here are some example pictures I have taken with my new telephoto lens:
