I wanted to buy the Tamron SP 35mm f/1.8 VC. After reading all the reviews and found a good sale price I went to the local store to check it out on my D750. I brought along my lens Nikon 16-35mm f/4 and expected the Tamron would beat it up. I took 2 photos of the same thing in the store with the same settings for both lenses. Here's my observation of the result:
- color and contrast: look great on both pictures
- center: the Nikon is slightly sharper
- upper corners: the Nikon is noticeably sharper
- lower corners: the Tamron is (very) slightly sharper
- AF is slower on the Tamron, expectedly.
I was disappointed but decided not to buy the Tamron. I was happy at the same time to see that my Nikon zoom has beaten the Tamron prime. However, it's possible that the Tamron lens happens to be a bad sample.
