Cons: Manual focus with this lens is near impossible due to the focus ring design. Plastic and feels cheap. Nervous bokeh. Performance in low light disappointing. I rarely use it.
Pros: Fairly sharp stopped down.
Summary: By all accounts the Pentax FA 50mm f1.7 was much, much better in all respects, sadly now out of production and quite difficult to find used.

Cons: slightly soft at 2.0, increasing to 1.4; required a few rounds of adjustments to in-camera autofocus calibration, but seems to work fine now.
Pros: Fast; small; nice rendering of out-fo-focus area; Build quality rated at 5 stars because this lens took a 2.5-foot fall to a hardwood floor, landing on its side which caused no internal or external damage.
Summary: [purchased used, but in very good condition]; The softness this lens displays wide open, up to f/2.0 is far and away the most disappointing characteristic of this lens, which somewhat undermines the main reason this lens is desirable, which is its speed. That said, on a crop-sensor camera, this lens is well suited for portrait photography and headshots, where a little softness is not necessarily a bad thing, as it can help hide imperfections in the skin. At around half the price of the DA* 55 f/1.4, the FA 50 f/1.4 is a nice addition to any photographer's camera bag so long as its limitations are kept in mind.

Cons: As an FA lens, not always perfect for a DSLR. I have focus problems at times. Price went up a lot in the last few years. It was $200 for a very long time and then jumped dramatically in price (sadly) before I bought it!
Pros: Great IQ, bokeh. Very versatile at 50 mm on a DSLR.
Summary: Great lens - get one!

Cons: Price has gone up... Can be a bit soft at wider apertures
Pros: Great image quality, widely available
Summary: This was the only lens (I bought K200D body only) I had for the first 11 months of DSLR photography. It continues to serve very well and deliver excellent images.

Pros: what a nice lens this is, 75 mm 1,4 on Pentax . Excellent quality, again Pentax feeling, special.. robust. So fine to work with this lens for low light portraits, together with the in-body anti shake of the Pentax. Here Pentax and Sony rules ! Beautiful bokeh .
Summary: value for money
