Excerpt: It is very enjoyable to take indoor and low light phots with this lens. I have Sigma 17-70mm lens as walkaround lens but after this lens I generally prefer to use pentax. And also it makes very good bokeh.
Excerpt: I use this lens to take pictures of my kids on trips, family parties, and social functions. The lens takes great pics of scenery in background as with a f 1.4 you have so much control of depth of field. Pictures are consistently sharp and professional looking. Lightweight and easy to change in a hurry. By far my favorite lens.
Excerpt: The fact that this lens is still in production, testifies to how good it is. The colors, IQ, sharpness and the build quality make this a must have lens if you are a Pentaxian. I love that this is a screw drive lens without any hint of weakness. I love the metal lens mount. I love the aperture ring. Such a great piece of glass.
Pros: Classic Design, Distance Scale, Fast / accurate auto-focus, Full Frame Compatible, Holds its value, Nice Bokeh, Strong Construction
Excerpt: I bought this 50 to pair with my K-5 IIs body and I couldn't be happier. Its versatile and takes really nice pictures. I will eventually want a zoom lens for my K-5 iis, but in the meantime this lens will stay as my walk around. So, far my only complaint is that its not waterproof, other than that the lens feels heavy and solid.
Pros: Consistent Output, Durable, Fast / accurate auto-focus, Nice Bokeh
Excerpt: i bought this lens to supplement my 18-55 and 55-300 which i have used very actively on my k-x (i have taken over 50,000 pictures with the camera). i also have the M 50mm 1.7, but i thought it was time to get something with AF. I wanted it mainly for pictures (portraits) of my kids, and also for product shots which i do from time to time. anyway, lens came, but very quickly i realised that it wasn't focusing perfectly.
Pros: Durable, Lightweight, Very Sharp When Focused
