I know sigma is more popular, but i've read several reviews with people saying that tamron is sharper. And the big diff is that tamron is $100 cheaper than sigma!! I could well save $$$ for a 50mm prime with the tamron.
However, i'm afraid of getting a lens that is so lousy i dun wanna use, so tamron users please feedback to me if the lens is sharp enough. I dun take much sports... just want to get portraits with acceptable bokeh, as well as occasional animal shots. Would the tamron suffice?
One more thing... is the built quality of tamron acceptable? Is it metal/plastic mount? Thanks.
