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. The autofocus seems a little slow, and it can be a little frustrating to get moving kids in focus. That may also be partly my fault because I am inexperienced shooting at those larger apertures.
Excerpt: Dear Friends,,,Yesterday I bought this lens and today I am writing a review just because of few pics I took of my children in a very casual way. The pic I am showing below was taken hand held in a very casual way. I was amazed by the sharpness and clarity this lens produced which I was not expecting. Although this pic is taken at f/3.2 but the sharpness/clarity this lens produced is amazing.
Summary: I started out in film cameras and used a collection of prime lenses. One of my favorites was a Pentax 50mm 1.4 lens. It was the lens that I used most and I got some amazing pictures with it. I have had some of my photographs published in national magazines and I won an award with Kodak back when so I think I have a pretty good "eye.
Excerpt: This lens has been compared to FA50/1.4 quite a few times and one can wonder what you get for a lot more money. It is similar in sharpness with apertures smaller than f/2.8, but at f/1.4 to f/2.8, the newer DA*55/1.4 has better sharpness and more contrast. It is also easier to manual focus with it’s larger focus ring. Build quality is top class. I was not pleased with focus accuracy on K-5, but K-5 IIs have changed that. Focusing is almost perfect with K-5 IIs.
Excerpt: Everything you've read about the image quality and sharpness of this lens from past reviews rings true. Price wise it is a hard pill to swallow especially with the slow AF. If the AF was screwdrive quick, I'd be more than happy to swallow the high price. I find the AF is fairly quick (not screwdrive quick) when changing focus between objects that aren't distanced too far apart and it also seems to depend on the type of light you're using.
Pros: Sharp, sharp, sharp, color rendition, sharp, quiet, wr, sharp
Cons: Slow AF, price, some chromatic abberations depending on light
