Hi all. Would be a great favor if other 15-30 owners can have a look at the full res sequence and let me know if it looks about right, or worse than yours.
I'm on a 3rd copy of this lens, first two purchased from Adorama were not good, this one from Kenmore Camera seems better, but maybe a bit worse than I expected it to be being such an expensive piece of gear,
and reading stellar reviews for Tamron 15-30 as well as the Pentax version.

Pics are a bit processed, mainly to make details easier to see (raised shadows), and added a bit of sharpness to emulate a closer look to my usual working files.
Center is very good at all apertures, sides however are weaker, which is to be expected I guess.
What i've noticed is that with af I cannot nail focus spot on, and if it's off even by a tiny bit the sides go very soft. I don't know if this is my camera's issue at this point. I might have to send the lens together with the camera
for tune ups, which is pretty annoying since shipping such heavy items, and insuring them would cost quite a bit. Hand holding shooting does not work for me, I will to calibrate the af with a target within next couple of days,
see if that does anything for me. I took the lens on a trip yesterday, and majority of the hand held shots had soft sides due to focus being off by a hair. I tried single center point, 9 point, afc, afs and about every combination
I could think of lol, but I can't achieve consistent results yet.
Pretty tired of the process, my enjoyment of the purchase is spoiled, hopefully it comes back after few more shoots with current lowered expectations)
If anyone's interested - my previous 2 threads about the other 2 copies I had are here:
