Not as sharp as a Powershot!
10 February 2011
Summary: I bought this lens for an upgrade from a Powershot S3IS to use with a Canon 40D SLR. In comparing shots with this setup, the Powershot S3IS produced noticibly sharper and better contrast photos. Thumbs down.
Summary: I bought this lens for my Nikon D5000. I did some research and read that it is compatible with my camera. When it arrived I found that the auto focus didn't work at all. I immediately got on the computer and started reading other reviews to discover that many other people had the same problem, or intermittent auto focus. After more research I discovered it was not compatible with the D60, D80 or D5000.
Summary: I bought this lens for its great reviews and unbeatable price. However, after a couple weeks of extensive test shots at various settings I decided to return it. The picture quality is the main reason. Actually I decided not to pursue the type of all around lens (18-200+). Pros: versatile, portability, build quality and price Cons: picture sharpness issue, lens creeping, and no image stabilization.
Summary: after research i figured the lens would be pretty good, but after testing it out for 2.5 weeks, i was very disappointed in the quailty of my pictures. pictures weren't as sharp as i would have hoped they would be. i ended up returning the lens.
Summary: optics are far better that from IS/non IS kit lenses that comes with Cannon XTi. pictures are better, clearer, brighter and so on an so forth. i.e. lens optical qualities are really good. not as good as L series of course but for value/money might be best selection. however there is the big downside: every time you tip the camera downwards, lens retracts!
Conclusion: I had high hopes for this lens after reading the reviews. My experience with it was quite different. I have used it extensively for a year now and am lucky if I get 20% usable shots. It has a great wide angle with no vignetting and most wide shots are sharp and contrasty---I love it. BUT, as soon as I get over 70mm my shot ratio decreases terribly, even in shutter speeds of 1200-2500 and a normal ISO of 200-400, the pictures are overwhelmingly soft.
Pros: Size, range, price, great wide angle images
Cons: Horrible zoom images, lack of image stabilization, f/stop not consistent across range
Summary: I bought this lens in May 2007. I have used it quite a bit. I liked the zoom range 18 to 250mm is the sweet range for a all-in one zoom. I also have 3 Canon lens and had a Sigma lens (28 to 300). Well this fall I took the Tamron only on a trip along the Blue Ridge Pkwy. I started to notice it would de- focus as I zoomed out for wide angle shots - when I got back I found over half my shots were out of focus- since most were wide angle (45 to 18 mm).
Summary: Based on the reviews and articles on this lens it seemed to be the answer to a multi-year search for an ideal travel lens. It appeared to be one travel lens, of acceptable weight and size, that would do it all with acceptable sharpness! With great anticipation I ordered the lens. It arrived and I loved the size, weight, and zoom range. Alas, my enthusiasm was destroyed when I reviewed my first images. I am not difficult to please ... but this lens didn't even come close!
