The K-3 is the latest and best in a well-established line of high-end APS-C DSLRs. The K-3 offers a wealth features for still photographers, including a large, 100% coverage viewfinder, solid build, and plenty of customization. Its video capabilities are a little less inspiring, but it stands as a great stills camera that's a pleasure to shoot with.

    More than a simple upgrade

    I do not consider myself being a professional camera tester, I'm just a happy user. This camera is a class of its own. It's more than a simple upgrade to the K-5 I have used before. I like - fast and accurate AF - very quiet shutter - sharpness (a very good lens provided) - overall responsiveness (fast memory card provided) I do not say that noise is worse. In my opinion, a little noise somehow produces a perception of crispyness. You will never see it on moderate-sized prints. However, when ...

    Better in every way

    The early impressions after 3 weeks of casual snapping are very positive. This body is an upgrade to a K-5 which got used a lot over 2+ years. Pentax/Ricoh made numerous upgrades to a very good camera, none of the upgrades are game-changers but taken together the result is very impressive. To those unfamiliar with the Pentax K-single-digit family they are solid, reliable performers in robust, confidence inspiring bodies with excellent viewfinders & ergonomics. Compared to the K-5 the new ...

    Catching fire with a K-3

    I am an editor for a small weekly newspaper, and this morning at 5 a.m. the fire siren went off. I went over to my office and grabbed my new K-3, which despite having for a week, have shot nothing more than test shots around the office. I got to the scene and started shooting. I told myself I was not going to shoot 6400 ISO, but because of the conditions, I just went between 3200 and 6400. I have NR set to custom, with low NR for 1600-6400. I also have slow speed NR on. Impressions and thoughts ...

    Pentax K-3: Everyday fun with a powerful tool

    The Pentax K-3 is both a very continuous product for all people who have owned a recent Pentax DSLR and at the same time a large step ahead in so many areas that it makes the tiny upgrades some "new" camermodels get these days look ridiculous. So what is new for the K-3 compared to other Pentax DSLRs? (1) 2 SD card slots (2) focus peaking (3) 24 MPx sensor (4) Number of F2.8 AF Sensors now is 3 (5) AF sensitivity is up to EV ...

Questions & Answers


K-3 low light AF performance?

Fast question, one of the biggest selling points I read about on the new K-5 models was their -3EV capable AF. Anybody know what the rating is for the K-3? I can't seem to find the spec on it, thx in advance.

Manual page 92 Yep -3EV ... I think metering down to -3EV is new, I believe the K5's stopped at 0EV. Continue Reading

Just to chime in. The K-5II/IIs also have -3EV sensibility. Completely destroys the K-5 in that respect. Continue Reading

Also, the K-5 II and IIs have a central f/2.8 sensor, the K-5 does not. The K-3 has three f/2.8 sensors. Continue Reading

Gordon Laing has this to say about the topic: "several months in this business is a lifetime, and there's no commercial point in Camera Labs reviewing a product that's a few months old. Believe it or not, even a few weeks makes a big difference in page impressions and revenue generated." Continue Reading

They made a half-assed commitment to it when the camera came out top of its category and second overall in the user voted "of the year" awards. Something along the lines of, "we've heard you, now we'd better get reviewing the K-3". Rumour says Ricoh didn't invite them for a caviar buffet, so they're scheduling that camera last. Scandalous? Absolutely. They also never responded to my question of whether the AA simulation was engaged for their test shots. So much for the general level of competence around here. Continue Reading

Changing technique for new sensor

Hello, After reading a lot about people not getting sharp results with their K-3. I then watched photouniverse's video about it and how he was able to get perfectly sharp images with it. However, he and many others said that since Pentax have used the same sensor (or at least the same resolution sensor) for many years now, people are used to that. He then says that moving form 16MP to 24MP would need a steep learning curve. It is also mentioned numerous times that it is a matter of fixing your technique in order to get the most out of the camera. What I don't understand is what those techniques are. He never actually gives any examples. What exactly is it that we need to change to get the best results? Could someone please explain this to me? thanks, Albert

Landscape photographers will do the following to maximize resolution. 1. Always photograph using a nice sturdy tripod. 2. Always photograph using a nice sturdy tripod. 3. Use the sharpest aperture on the lens (f/8, f/11) 4. Use mirror lock so that there are no vibrations introduced during exposure 5. Use a cable release or remote so that you are not touching the camera during exposure (I use 2 second self timer, automatically locks the mirror too) 6. Turn off VR, IS or SR. (Mirror lock turns this off on some cameras) 7. Use the lowest ISO the camera offers (80 or 100) Using f/8, f/11 at ISO 80 will force slow shutter speeds, so you'll need a tripod one way or the other. My average shutter speed is 1/8s. I know people hate bringing a tripod, but it is the most valuable tool I can think of. Don't cheap out  either if you are looking to buy one. A poor tripod will ruin your day. Don't want to shoot doing all of the above? That's fine, just don't expect to get the most out of 24mp that ... Continue Reading

I find it hard to believe that an increase in the number of pixels is going to make camera movement more visible, assuming the same size output - print or screen - from both cameras. The visibility of blur from camera shake is a function of the degree of displacement of fixed points during the time the shutter is open. At a given output size, the length of that displacement is going to be the same, regardless of the number of pixels. Of course, if you look at the two images on screen at 100%, motion blur will be more visible with the higher-pixel camera. Continue Reading

So.. that takes care of the static landscapers. But what about the rest of us that walk around forests with a 300mm lens, handheld looking for wildlife. We have been getting superb images from K7's, K10's and the K5iis but suddenly, our 'technique' is not good enough? I'm sorry, but I can't accept this. Maybe I just need to swap back to my trusty K5IIs. Tony Continue Reading
