reviewswhat are people saying

"I like to take shots from far away so people will act normal when they see a camera. It gets the photos I want and its light weight. "

bhphotovideo.com

"I love using this lens on my Pentax Digital camera. It has a good overall range, and the results are sharp and crisp."

bhphotovideo.com

"I wish it was a little easier to put on the camera and The focus tends hunts in lower light on the K10d, which can be annoying because it takes forever to rack all the way from one end to the other."

I have had this lens since it first came to market. I use it as a wildlife lens; at first with film and now with digital Pentex K5. Gives me 450mm if needed. Macro is handy. Price is good. I like it.
