Excerpt: Having grown tired of the "standard 18mm" width, I had to break out. I was missing way too much. I really weighed the Sigma 10-20 against this Tamron and I am so glad I went Tamron 10-24. It is like falling in love with photography all over again. The hard part is taking it off and using a normal lens from time to time. Now I know what I have been missing in my quest for creative photography. Bang for the buck, this lens is clean, responsive and true!
Pros: Consistent Output, Durable, Nice Bokeh, Strong Construction
Excerpt: I got this lens primarily to open up my landscape photography field of view. I received the lens during one of the worst (weather-wise)winters I can remember and haven't ventured outside for long enough to try this lens out with landscapes yet. I have, however, found that playing with perspective shots is a whole lot of fun! This lens is well-built and feels very sturdy and operates very smoothly. Focus is nice and fast and accurate. I really like the range of this lens.
Pros: Durable, Fast / accurate auto-focus, Lightweight
Excerpt: I have been using this lens to photograph landscapes and large outdoor fundraising events. It has excellent depth of field and angle of coverage that enabled me to get in close with a wide view. On an APS-C sensor it is the equivalent of a 15-36mm lens on a 35mm camera. I did not notice any significant issue with focusing under the bright daylight conditions in which I have used it.
Pros: Easily Interchangeable, Good depth of field, Strong Construction, Wide Field Of View
Excerpt: I needed a new wide angle for stadium shots and landscape. My former wide angle, a Sigma 17-35, never clearly focused on the right side of the images for some reason. I already owned 2 other Tamron lenses for my Pentax K-5 and K-5 IIs bodies, a 28-75 f2.8 and a 70-200 f2.8. Tamron seems to be a perfect match with the Pentax bodies. Just like my other Tamron lenses, this 10-24mm is producing superb images.
Pros: Consistent Output, Easily Interchangeable, Fast / accurate auto-focus, Lightweight
