Excerpt: This lens is one of the finest lens I own. Excellent image quality, focal length FF equ. 82mm (for photographing people) and it's fast. Really excellent when used with higher resolution sensors such as 16Mpixels, 20Mp and 24Mp.
Pros: Fast with amazing color rendering, fast silent AF
Cons: Price, SDM (although does not seem to fail with this lens)
Excerpt: A great lens for artistic photography, this receiver is 85 mm 1.4. The only thing I do not like is the autofocus, it is much worse than my other lenses. Figure pleasant, sharp and expressive as crystal. My favorite lens Pentax
Pros: sharpness, artistic drawing, bokeh, not afraid of the sun on the forehead, working 1.4, easy focusing ring
Excerpt: I have missed my 85 full frame from film days and this IS THE ONE to replace it. Have only had it a short while but am very impressed. Couldn't pass it up at the price (like new in box with caps and shade). Wonderful portrait lens...if anything it may be too sharp for that purpose.
Summary: Here I am several years after buying this lens on Amazon and I never cease to be blown away but what it can do. When I say what it can do and not what I can do I mean that. I am NOT a professional photographer by any stretch of the imagination..
Excerpt: Incredible lens. Optically is as good as it gets. This is my favorite lens and it has done wonders for me. At F 1.8 you can put this on a 24x36 and have no issues with sharpness or rendering. It truly is an amazing gem when it comes to resolving power.
Excerpt: When I bought the K-30 I knew from reviews and pictures on PF that I wanted this lens as I was interested in portraiture and night shots. It was my first prime after the kit 18-135 WR that came with the K-30.
Excerpt: This lens has produced some absolutely stunning images for me. I mean some real keepers. This is my first 1.4 lens so I may not be used to having that large of an aperture. However, with that said, when this lens focuses correctly, it is sharp as a tack.
