TAMRON B001C700

Nice wide angle lens for the price, and with rebate the deal is even better. Seems to focus quickly, and is reasonably sharp from f8 up. Great for HDR shots,and Adobe Camera Raw and Lightroom 4 already have a profile for this lens to adjust for the...

Could be Sharper at lower f-stops. Lens cap doesn't like some polarizing filters(doesn't stay on), but no biggie. Chromatic aberration can be strong but the new lens correction tools in either Lightroom 4 or Adobe Camera Raw can eliminate that problem...

Inexpensive lens (compared to Canon) that can give you a view of the world that you won't get with ANY of the kit lenses. This is a wide angle lens without the "fisheye" view (might want to confirm that with the fishes). When using this lens with a...

-Sturdy build -Good image quality -Lens hood included -Easy to use-not a huge learning curve -Great for Landscapes+Architecture

Can be a bit soft at the 10mm range. f6.3 or smaller produces sharper images. A bit of chromatic distortion at 10mm, clears up about 14mm. Very simple to correct with software. Slow AF motor, but the search is very quick (does not over correct like...

good contrast, image quality
