Sensor
At the heart of the K-3 III is a new BSI CMOS APS-C sensor. Ricoh describes it as a 25MP chip, but the cameras resolution is actually 25.7MP, raising the possibility that it's related to the one using in Fujifilm's X-T4 (albeit with a more conventional color filter array and no pixels masked for phase detection). Either way, the sensor has no anti-aliasing filter and is capable of 14-bit readout at up to 12 fps. Ricoh says the new sensor has better high ISO noise characteristics than the 24MP...
Viewfinder
One of the most significant revisions in the K-3 III is an all-new viewfinder. Building on a Pentax tradition of large, prism-type viewfinders, the K-3 III's viewfinder is a pentaprism offering an impressive 1.05x magnification. Viewfinder magnification figures are usually calculated with 50mm lenses, regardless of sensor size, so some of that high figure comes from the apparent magnification of the camera's APS-C sensor. But, even taking this into account, it would be equivalent to a 0.68x m...
New Autofocus module
Ricoh has developed a completely new AF module for the K-3 III. The Safox 13 has 101 AF points, 25 of which are cross-type. 41 of the AF points can be manually selected and the centermost nine points can focus at down to -4EV when paired with lenses that are F2.8 or brighter. The optics in front of the lens module expand the coverage of AF points to be 20% wider in the frame than the Safox 11 module in the K-3 II. On top of this, the camera's continuous AF system has been completely reworked....
It's fair to say that the APS-C DSLR market is not what it once was. So we've tried to include meaningful reference points, however you choose to look at the K-3 III. If you're in the market for an enthusiast-level APS-C camera, Fujifilm's X-T4 is the one to beat. If you're not set on an APS-C sensor then you can get the very capable Nikon Z6 II fo...
The K-3 III iterates on the ergonomics of the exiting K-3 models, which we've frequently praised. We're pleased to be able to say that the K-3 III doesn't diverge too much from this pattern: the magnesium alloy construction maintains the impressively dense and solid feeling that its predecessors conveyed. And, of course, it offers the extensive wea...
For transparency it should be made clear that, despite press releases, teasers and mockups dating back to at least September 2019, we've not had too much time with the K-3 Mark III, hence the lack of image samples. However, the time we have spent, along with the details Ricoh has released make clear how much effort has gone into this camera. We als...

The Pentax K-3 is a 24-megapixel APS-C sensor DSLR with a selectable low pass filter and wireless remote capture. It was announced in 2013 and won several awards, including the TIPA Best Digital SLR Expert and the EISA Photo Award.
The PENTAX K-3 is a digital SLR camera with a 24-megapixel CMOS sensor without an AA filter, but with a world's first AA filter simulator to minimize false color and moiré. It also features a 27-point AF system, a 86,000-pixel light-metering sensor, and a three-motor mechanism for high-speed shooting.
