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
Excerpt: I did not think I needed this lens but it went for $17 on Ebay with a warning that the focus was sticky. I got it and opened it up and found a small piece of plastic in the focus drive gears. After that was removed it sat for weeks because it just felt so 'cheap' and did not give much confidence. Focus and zoom rings sound like they are grinding sand inside the lens.
