Re: Official: Tamron 35-150mm F/2-2.8 Di III VXD (Model A058)
Ok, so of course I couldn't just enjoy taking pictures, (sorry, it's stronger than me - did I mention already I'm more of a techie than a photographer ) I had to put the Tamron through its paces, since I really enjoy the focal and aperture range so much I wanted to know how my sample stacks up regarding IQ.
I compared it to another sample and found 2 "interesting" things...
1) I'm pretty sure now that I've run into the weird "haze" issue, that was reported previously, on the other sample. The interesting part is that it only affects the right side of the frame (and not even extreme edge, it's already visible around the horizontal level marker) and only up to certain distance, as I could not see it in my long range test shots (but was still visible around 135cm at 35mm f/2). This shot shows it pretty well (I know it's not flat, but believe me I have a lot of others, flat one too): lack of sharpness, contrast, detail + some "muddiness" (we actually call it soap around here ) / haze (easier to notice in original size via flickr link):
Top are 2 crops from AF-C focused shots from a series with the object on the left side of the frame,
bottom are 2 crops from AF-C focused shots from another series with the camera upside down (so the object on the right side of the frame).
2) The other copy is *much* sharper on the wide end than mine, it's actually unfair. I didn't compare extreme corners, just the left and right (horizontal) edge of the frame but the difference is massive. I'd say that at f/2.8 or even f/2 the other copy is sharper than mine at f/5.6 .
This makes me actually envious, as I did not expect this high level of sharpness from a 4x zoom (my copy only catches up around 70mm)... I think it's sharper on the edges than my 24-70DN (which I hope to sell soon ) at 35mm...
If my intended usage was landscapes, I'd try to exchange the copies, but since I will be mostly using the Tamron for people & stuff, "clean" image out of most of the frame when focusing on-point is absolutely required.
