Excerpt: I've owned the k2000 and k-x and thought those 2 were good cameras. I like this Pentax as well. My favorite part is the rechargeable lithium ion batteries, as the k2000 and k-x used AA batteries that were used up quickly. Cosmetically, I like it that they left the silver decorative chrome off this model. This camera performs well with high ISO settings.
Summary: I purchased the Pentax K-R several years ago so I had time to form a better opinion. Coming from point and shoot cameras, it took me quite a while to get accustomed to this camera's deep menu of features. Now I get great pictures at a faster rate. I mostly do people photography for public viewing, websites, and publications. The RAW file capability of the K-R is a must have when submitting images to many publishers.
Excerpt: I've been using the K-r for two years. ISO 3200 RAW is surprisingly clean - check the RAW noise charts in the review. 6fps great for action shooting. Problems: If you have lens corrections on, the images take a few seconds to appear on the view screen after you take them.
Summary: I bought this camera body to replace a film Pentax. I'm using lenses I had for the other camera. All work with the Kr, although one will not focus automatically. I don't know why Pentax is no longer a popular brand; it isn't carried in most stores. Yet the camera takes good photos. It does so many things that it is difficult for me to figure out, but I suspect all digital cameras are similar.
Excerpt: Reliable, ergonomically excellent, great RAW image quality (as far as i can tell, still better than 2012 releases like the Canon 650D/Nikon D3200), 6fps, incredibly cheap, light, decent VF, easy menu layout, HDR, customizable 'green' button, fast start-up, many other features like the ability to convert most recent JPEG to raw with one button press etc.. Another massive advantage of going with the k-r (or most Pentax DSLRS) is the awesome in-camera SR (shake reduction).
Summary: I have long wanted to get a better camera than the frustrating Point and Shoot type. Way back in the film days, I had a nice Yashica and my wife an Olympus SLR. In 2001 I finally went to digital and haven't looked back. But even the best compact P&S cameras try too hard to take the picture for you, so if you are like me and want to have control over as many aspects of your photography hobby, then you need to graduate to a DSLR.
Summary: My previous camera was a Panasonic Lumix with 10x zoom and excellent feature design. It was a great little camera which unfortunately I ruined when I dropped it in the surf. My decision to buy the Pentax was inspired partly by my frustration with outdoor photography without a viewfinder. I chose the Pentax based on having had one many years ago and really liking it, and from the reviews of this particular model.
