Excerpt: Bought this lens from a retailer clearing inventory, at an excellent price. Turned out to be a good value - decent sharpness, relatively compact and reasonably good materials and construction. It hunts for focus, but I don't use this lens for action photos, so this is a minor drawback. It doesn't get as much use as other lenses in my system, but if conditions are going to be rough, I can relax knowing trashing it won't be a financial disaster.
Excerpt: This is a nice little lens and is at least equal to the Kit Lens 18-55 in IQ, value and handling. For me, it's biggest drawback is the wide end, not really wide enough and close focus distance but the longer end to 70mm is a very very usable focal length!
Excerpt: The FA 28-70 f/4 is probably one of Pentax's most underrated lenses. It features a constant aperture in an ultralight package, coupled with an very good optical formula. I've owned it for close to a year now and been using it most of the time so I hope I do justice for this lens with the following review. Unfortunately for this lens I just acquired the FA 28-105 f/4-5.6 PZ so it will now sit in the box more often. I also wish I had a hood for it too.
Excerpt: After reading many good reviews, I bought this lens over ebay. My main purpose was to have the 50mm> focal length for portraits. My 18-55mm kit and 16-45mm wide zooms are good but fall short in the focal range.
Pros: Surprisingly sharp, color rendition, light weight
