This thread hasn't seen much action recently; I just acquired a used Tamron 10-24 at a reasonable price and have been playing around with it the last few days. Have taken only a few quick snapshots but I'm quite satisfied so far-- love the ability to go from 10mm to 24mm in one quick turn of the zoom ring. Sharp enough for my purposes and for the price I paid. Surprisingly lightweight and compact, nice balance on my K-X. I may end up using this zoom more than my DA 15 when traveling-- super convenient!! (But obviously I'll keep the DA 15 for times when IQ is of the utmost importance).
A few quick snaps, both at 10mm.
