Ah - prices. Thought I'd spare you :^)
The Q-ray was $144, and that Sigma 28-90 Macro was $10 and change. :cool: Deals, steals, either way it makes up for my failures at several C-City stores. I'll grab a tripod and shoot a thing or two in the near future. All prior tests are hand-held. I took the series below with both lenses, this is a) the Sigma series and b) too small to prove anything. The Tamron shots were in essence identically sharp, but the trees in back were weirder for bokeh.
My very first new lens was a Sigma 18-125, and the kit lens was sharper! Back it went, and I've steered away from Sigs since then. I'd read that their 18-200 outgunned that lens, but I jumped straight to the Tamron 18-250 with no regrets. Now? I'd like to let the Mega Tamron go for a 17-70 (or 17-50) to get my faint-light failings fixed. I've a Minolta 50/1.7 for real low light, but the 17-70 would also give me close focus so I could sell that 28-90 for a killing.. maybe $11?
