Sigma AF 28-70mm f/2.8 EX Aspherical

Great lens, probably best macro in price range. I bought this for my Sony Alpha 200 after doing alot of research and finding that for the money this lens is best in it's particular class, and I was not disappointed. For taking nature shots of insects and flowers, this lens rocks, gets super close, has a buttery bokeh, it's a fairly fast lens as well. I haven't tried any portraits but this thing will probably do those great too. The only drawback I can think of is it is noisy so if you are trying to sneak up on wildlife, this lens will give you away, heh. Other than that, definitely worth the purchase.

Good build quality and sharp image Lens takes high quality images in many conditions. It's become my daily carry. Minor autofocus issues where the lens will try and track to macro at distance shots. Still recommended.

Sigma 105mm f/2.8 Macro If you are looking for a lens for good close up photography, this one is great. A little loud, but who cares...... I take photos in my reef tanks and they are coming out awesome with little to no changes to the camera settings.
