Title: Awesome performance for the money
Review: I've used this lens with great success with both my 7D and my a100 - but if you don't need the range, this lens isn't for you. It's heavy, it zooms sluggishly, and it doesn't have HSM since Sigma never made an HSM version of this lens for the Sony/Minolta family, contrary to the listing.But if you DO need the range, this lens is capable of taking professional grade photos all the way to 500mm (use a tripod!) Besides the awesome range, it has excellent build quality. It feels solid in your hands, and can take a beating. It has great bokeh, color/contrast, and sharpness (in daylight, of course.) The size actually helps with keeping the camera still while shooting without the tripod, coupled with the super steadyshot of the a100 this lens can be used handheld in daylight.It's slow, but perfectly capable in broad daylight. If you plan to stick to focal lengths of below 200mm, go with a smaller, more portable lens.
