Summary: Excellent value!!! Sharp wide opened and gets even sharper stopped down a little. Excellent contrast and colors!!!! I first bought FA 50mm f1.4 whish is a good value as well (not as sharp wide opened but gives better bokeh and offers 1.4 at 50mm. However, after purchasing this one, I rarely use the 50mm. This one also is easier to use indoors as it is a little wider and still great for portraits.
Excerpt: My copy was purchased at B&H, it is silver assembled in Vietnam, with one year warranty. It is beautiful and looks great on my black K3. I was hesitating to buy this lens because I have the DA40/2.8 that is a superb lens, and a pancake. However, I got into this one. Now, I do not want to get rid of the other one. They are both so good.
Pros: Sharp wide open, small, beautiful, color, IQ
Excerpt: This review is for a mint condition 'Made in Japan' FA43 bought second-hand in Sweden, serial nr in the 0026xxx-range. Initial review based on experiences with the K-5 mk1, now updated after 6 months use with the K-3.
Pros: Build quality, small size, rendering, haptics
Excerpt: I mount this lens onto A7R via an adaptor. This is a very good quality, small and high precision lens. It is very sharp with good rendition beautifl color lens. I could use it in wide open and get excellent picture. Small, light weight, good manufacturing process, good material, great optical performance, FF lens and very competitive price. What I want more?
Excerpt: This lens is right in keeping with other Pentax primes - sharp, fast and delivers wonderful colors. I use this, the 15mm and the 70mm almost exclusively for magazine-quality work. Why the professional community hasn't embraced the Pentax line more enthusiastically is beyond me.
Pros: Consistent Output, Fast / accurate auto-focus, Lightweight, Nice Bokeh
Excerpt: Mine is a silver MIJ version. This lens is really a perfect combination of speed and size. I was a bit skeptical of the focal lenght before buying 43 ltd because I have never really liked 50mm lenses on APS-C camera. As a great surprice 43mm is just the right amount wider and I like it a lot. Image quality is also very high. Sharp, good colors and nice bokeh.
