Finally I decided to make this little review video about my favorite DX lens.
The Sigma 17-50 mm F2.8 EX DC OS HSM. The focus in this video is on finding the sweet spot or better said the sharpest aperture of this lens. I can already say that the result is amazing when you see the sharpness at 2.8! Honestly I did not expect that in comparison to F4, though I know that lens for a while.
To make this test a little deeper I not just took some shots with the Sigma 17-50 mm F2.8 EX DC OS HSM in the different apertures but also did the same tests at different focal length.
Let’s have a look in the video above.
