Average Reviews:
(More customer reviews)This is a good all purpose lens. The 28 - 300 mm zoom equates to approximately 42 - 450 mm on most DSLR's. There are almost always tradeoffs in anything you buy and this is very true with lenses. This lens provides a wide zoom range, has a minimum length of 3.3" and weighs about 1 lb. It is not very fast with a maximum aperture of F 3.5 at 28 mm and 6.3 at 300mm but when used with a Pentax K10D the automatic focus works well under most lighting conditions. I use it primarily for nature photography. It has produced good images in most situations. Although it focuses to 1.6 feet throughout the zoom range, to provide a 2.9 magnification ratio at 300 mm, the short depth of field results in disappointing close-up shots. Overall I am pleased with the Tamron AF28-300 and would recommend it to anyone that wants one lightweight lens to cover a wide zoom range.
