Originally posted by lowlight As someone who has rarely posted on this forum but quite often uses it for the excellent lens reviews, I thought I would comment about this camera as it does look very interesting indeed. I'm a keen 35mm film photographer with old Pentax cameras and some vintage Pentax glass, and have a cheap compact digital camera for point and shoot convenience. I've been researching DSLRs both full frame and with smaller sensors (e.g APS-C and 1" as in Sony RX10 range) for years (and I mean about 8 years which is ridiculous) without actually pulling the trigger on anything. I do want a degree of weather resistance and stabilisation for run and gun video. I wasn't sure about spending the money, but also knew something would follow with more of the features I wanted, so I kept waiting for better cameras to come onto the market. It's fair to say technological advances especially in sensor design have been rapid over the last decade so actually I'm glad I've waited. I'm sure there are lots of people like me who fall into that category. My main aim was to get a reasonably priced mid-range camera that could also shoot genuinely decent and nicely stabilised video at a good bitrate, especially in low light. An example would include the Sony A7sii which, alas, is beyond my price range.
I've finally this morning bought a Sony RX10 which is a very good weatherised run and gun video camera as well as being a more than acceptable stills camera. And guess what, an hour or two later this Pentax KP shows up online. I did consider Pentax mid-range cameras such s the K-50 etc, which seem to be exceptional value. But movie mode in Pentax has always (so far anyway) fallen behind other manufacturers and is basically unsatisfactory if you are serious about it - I've checked loads of video examples, and the moment you move the camera the image quality just starts to fall to pieces. I appreciate some here may disagree with that view, but really I was hoping for something better from Pentax.
What has impressed me about this KP is its extraordinary high ISO capabilities (yet to be fully tested), probably very good stills IQ, a weatherproofed body and upgraded IS - and I can mount PK vintage lenses. Brilliant. Prices are likely to come down after launch too. So to a potential customer like me with no strong preference for a particular manufacturer, this camera appeals. I'm sure there are others looking for the same sort of features I am, so I just wanted to say I wouldn't be surprised if a lot of interest is shown towards this camera from non-Pentax users. I'm looking forward to comprehensive reviews to check out image quality and video and may end up buying one for shooting stills and video in poor lighting and bad weather conditions, while using the Sony RX10 for daylight. I wouldn't say the KP is cheap of course, but it really does seem to tick a lot of boxes.
If you want to try a Pentax DSLR, want a rugged pro-level building quality, and dont need a tilt screen, best bang for your money today are the outgoing K3 and K3-II. IMO, the KP is an interesting new design but it is not in the same league and the high price tag is just because it is the newest model. Compared to K3/K3-II, it is only worth it if you are interested in its specific features or smaller size and weight.
The claimed high ISO better performance is, IMO, as regards the new sensor, probably around 0,6 EV, which means the raw output of KP at ISO 5000 should be close to that of K3/K3-II at ISO 3200.
If you look at the high ISO samples on Ricoh-Pentax website, (
Features1 | PENTAX KP | RICOH IMAGING) you vill see that, even at VGA screen size, pictures above ISO 12800 are very noisy and low definition.
The ISO 819200 setting is just marketing hype, the claimed high ISO improvements thanks to better processing apply only to JPEG output, which is not good in K3 at ISO 3200 and above, you get better IQ by proocessing the raw files in your computer (whereas up to ISO 1600, save in high contrast or badlit scenes, the out of camera JPEGs are nice).
