Pentax SMC FA 31mm F/1.8 Limited Reviews

Photozone reviews the Pentax SMC FA 31mm F/1.8 Limited and writes;
“The Pentax SMC-FA 31mm f/1.8 AL Limited is an excellent lens. It is already sharp at f/1.8 and razor sharp at medium apertures. Distortions and CAs are very well controlled. On the downside it vignettes quite a bit at f/1.8 so the ultra-large max. aperture takes its toll here. The bokeh (out-of-focus blur) is very smooth and buttery which is fairly unusual for a lens with aspherical elements.”

Pentax SMC FA 31mm F/1.8 Limited User Reviews

Greatest lens I have ever used, period. | Rating: ★★★★★
“This is the most incredible lens I have ever used. Razor sharp even wide open, with silky bokeh and beautifully rendered color transitions. There is a luminosity to images that I have never seen with any other lens. The all-metal build makes this lens a joy to have in the hand, and the slightly damped focus ring makes it a terrific manual focus lens. One finger is all that is needed to focus manually, making it feel more like a rangefinder lens than an SLR lens. My favorite lens, both on my K100D (46mm equivalent) and my old MX. “ – by Finn C. Pillsbury

Ultimate lens! | Rating: ★★★★★
“This lens is incredible. The contrast is top-notch straight from f/1.8, as well as sharpness. The colour rendering is accurate. But the most amazing feature of this lens is the bokeh (out-of-focus areas). it is very progressive, butter-smooth, really beautiful. The lens itself is all metal, very well built (apart from the lens cap that is plastic, such a pity). Really a must-have for pentax and samsung users, very difficult to get it off your camera :)” – by _antoine_

One of the Best Primes Ever Made! | Rating: ★★★★★
“I’m not the first and will not be the last hobbyist or professional to extol the virtues of this impeccable product. But beyond that, there has been so many reviews written about this archival quality photo glass that my comments would be psaltry. So suffice to say, it’s everything good that has ever been said about it. Coupled with one of Pentax’s fine Digital SLRs with Shake Reduction (or without it) you can count on getting some of the finest, sharpest, most detailed images recordable.” – by R. Jones
