Sigma 28-105mm F2.8-4 Aspherical Lens for Pentax-AF Camera

Rating:
Summary: This lens has a lot to offer.
Review: Don't overlook this lens. It does not have the longest zoom range available. But the F2.8 maximum aperature, the very serviceable 28-105mm range, the weight and size, the high quality of material and optics, and the price make this a pleasure to use and carry. If you want to carry only one lens, you need a longer range than this one has. But if you are going to carry two or more lenses, this one deserves to be in your bag.

Summary: An excellent "universal" lens
Review: I have always been a fan of Minolta bodies and Sigma lenses - they work great together (currently I have a Minolta Maxxum XTsi). This lens is certainly no exception. In fact, this one is the best lens I've had. I was so impressed with this lens, that I have all but stopped using any other lens. The aspherical capabilities allow me to get in real close to my subject and come out with a very clear photo.

Summary: a fine lens indeed...
Review: This lens turned out to work far better than I expected. It really is a fine piece of work. I prefer to use it in manual focus mode because all the mechanical parts are smooth and precise, unlike most cheap AF zooms these days. The AF part is noticeably faster than Nikon's entry-level 50mm lens.
