Decent, but not great
Been using this lens for about a week now. Overall performance is Ok. The photos come out fairly sharp. However, when I switch over to my canon 50mm 1.

Just the lens I needed
This is a solid well made lens, f2.8, 7inch close focus approximate 1:3. I would like the lens shade to fit a little tighter. The pictures are great.

A great lens for the price
This lens is sharp and accurate. Its functions VERY well in low light and in up close, macro shots. Its awesome to have a minimum focusing distance of 8 inches!

Good lens! Glad I bought it!
It is a really nice lens for those who can’t or don’t want to drop $1k+ on the comparable Nikon 2.8 lens. It has nice bokeh. My copy was tack sharp. Highly recommended!

Great low light lens for my Pentax K20D
In 2007 I bought a Pentax K10D with the standard factory 18-55mm f/3.5-5.6 Lens. In 2008 I upgraded to the Pentax K20D 14.

Great Lens……Great Price!
After doing a few hours of research on these lenses I came to the conclusion that I wanted to go with the Canon 17-55 but couldn’t justify spending $1000 on it at this time.
