Great lens for full framers

If you use a full frame digital camera, you know finding a wide angle lens with greater field of view than 24mm can be difficult and expensive. For Sony a mount users (a99 for example) this lens is a dream come true. It is pretty much the same as the Sony version, but if you look you can find the Maxxum version for lower price.

I have only used this lens a few times, but it does a very good job. I like to shoot in aperature priority and stay around f8 or f5.6 whenever I can. The images are pretty good even wide open at f2.8. They are even better at f5.6
negative:lens sold not as "excellent"

the lens is obviously couldn't be described as "excellent"
some light but obvious scratch on the front glass
one obvious dent on the filter ring
not as the one i preferred
comment:I had this lens on my wish list for a couple of years. Since I prefer prime lenses to zooms, this one fills the gap between my 14 mm ultra wide and my 30 mm wide-normal in my Sony A-mount (APS-C) kit. The images that I have gotten with it are acceptably sharp for my needs. I would not recommend it, though, for professional use because of its plastic body.

So far I have used it for close-up, non-macro photos of flowers. It does a good job of stretching the distance behind the subject while keeping decent depth of field. I still look forward to using it for landscape work. Although I know that there must be some distortion in my images using the lens, I haven't noticed it because I haven't photographed any buildings with it. That's another thing I am looking forward to.
