Excerpt: First, the negatives. This lens does not compare in quality to any of the other Pentax lenses I own, and even the Sigma 18-50mm kit lens I got with my *ist-DL feels a little better built. It rattles and the plastic feels almost toy-like, especially around the mount.
Pros: Compact, lightweight, adequate IQ for casual shots
Excerpt: Light weight, wide to tele focal lengths, pleasing results make this a keeper in my book. And I will be able to use it on the new full frame digitals, in case someone decides to donate one to further my photographic pursuits! Buy now before the crowd decides it is undervalued.
Pros: Price, full frame, color saturation, contrast,
Cons: plastic mount, sharpness at wide aperture, barrel distortion
Excerpt: This poor little lens does seem to be one of the 'whipping boys' of the range. It is, even so, an SMC Pentax lens, with a very useful range, efficient auto focus, great contrast and colour saturation, and can be picked up pretty cheaply. What's not to like?
Pros: Useful range, lightweight, good value for money.
Excerpt: Little can be said abut this lens. It's a good kit for starters, because of its price and zoom range. IQ is so-so, but not for prints. Bokeh is also good when the shots are made outdoors, and it doesn't render points of light very well, also masses of leaves.
Excerpt: I've had this lens for a while. I originally used it on a k1000, but found there to be minor issues with the old body and new lens. I had to have the aperture lever repaired once because the k1000 was a bit hard on it. On my PZ-1 it's been nothing but creamy goodness.
Pros: CHEAP! Good AF speed, Aperture Ring
Cons: Plastic build, filter size is a bit big, no DOF scale
