Excerpt: The VC is not functioning properly. If it is on, at slow shutter speed it blurs the picture. I had to turn it off if the shutter speed was faster 1/13. I had 3 copies of the lens, 2 of them were really soft. The one that was actually "sharp" had the AF that dies after few weeks of light use...IQ is not too bad (similar/little worse than the 18-55 IS). The range is of course very good. It is not fast, but you cannot expect a 15x zoom to be fast.
Pros: Compact Design, Easy To Use, Long range
Cons: No Increase In Performance, Poor AF, Poor Clarity, Poor VC
Excerpt: I use this lens as the lense usually attached to my camera. It has a very large zoom range which makes it nice for a variety of situations. The focus motor is quiet and for the focal range, its nicely compact and easy to store. Generally, it takes very nice photos, not the sharpest at the long zoom range but then again, you may not buy this sort of lens expecting the tack-sharpest results in the first place.
Pros: Durable, Easily Interchangeable, Lightweight, Strong Construction
Tamron 18-270mm f/3.5-6.3 Di II VC PZD Aspherical Lens Pro Kit for Canon EOS for $457
6 February 2011
Summary: Purchased the Tamron 18-270mm f/3.5-6.3 Di II VC PZD Aspherical Lens for Canon from Beach Camera for $457. Was looking for an ALl-In-One lens and Tamron fits the choice with 18-270mm lens giving me enough zoom capability that I was looking and also, for the holidays Tamron was running a $100 rebate which bought the price down to reasonable level. This lens was more expensive than my camera and I hope you research your needs and then purchase the lens.
Summary: Took this on holiday to India and was pleased with its range and ease of use. It is light enough to take anywhere and I didnt use any other lens. The down side for me was that on maximum magnification I needed a tripod, which is to be expected, but still a problem when travelling light. Also my camera is a Canon 60D and I found that when I was using the live view focus, which I do quite frequently, it was unacceptably slow.
Summary: This is wonderful lens in All in one category, Very Silent AF motor, Fast AF, i mean fast in low light conditions also. Sharp and clear images, also i loved the VC of this lens. Perfect lens for my kinds beginner. The price for this lens is reduced internationally.. Can be easily available for 25-26 K in India.
