#PENTAX FRAME SENSOR ISO#
There’s plenty of latitude to remove RAW noise from images through ISO 6400 without sacrificing undue detail. There’s a fairly sharp drop in image quality in JPEGs moving from ISO 3200 to ISO 6400. The camera shows an excellent dynamic range but its ISO performance in JPEGs isn’t topping its full-frame peers. The K-1 produces “super punchy” JPEGs, Patiño says. The K-1 uses a slow USB 2.0 port, which makes tethered shooting something of a no-no with this camera, Patiño says. The top LED display is rather small to accommodate two large dials, making camera info trickier to read from the top down. For one, the mode dial has two locks, which can get cumbersome as you’re adjusting on the fly. Patiño did have a few quibbles with the design, though. There are also tiny LED lights placed strategically around the camera to illuminate things like the memory card door or lens mount when you’re working in the dark.
It’s great for those times when the camera is mounted at difficult angles, but does also lead to some extra fiddling in the process of pushing the display back in place. The first is the rear “cross tilt” LCD, which pulls away from the camera and can be swiveled not just up and down, but diagonally as well-something no other camera display can do. Ricoh gets design points for a few clever features. Its durability comes at a price, though, as the K-1 is heftier than competitive DSLRs like Canon’s 6D or Nikon’s D610. It has absolutely terrific ergonomics and is rugged and weatherproof to boot. It looks like a camera that a camera nerd would build (we say that lovingly). Ricoh clearly unleashed their engineers to cram as many buttons and dials onto the body as humanly possible. The GPS not only provides location tags for images but combines with the built-in compass and shifting sensor to enable’s Ricoh’s ASTROTRACER function, which lets you keep stars sharp during long exposures of the night sky. There are a pair of SD card slots, built-in Wi-Fi and GPS. It’s capable of focusing in low light down to -3 EV. The autofocusing system uses 33 phase detect points (including 25 cross type focus points in the center) when focusing through the viewfinder, and contrast detection when in live view.
The shifting sensor is also responsible for in-camera image stabilization good for up to five stops of correction, per CIPA standards. There is, however, an AA filter simulation mode that can mimic the effect of an optical low pass filter by slightly shifting the image sensor. The K-1 boasts a 36.4-megapixel CMOS sensor with no anti-aliasing filter. We teamed with NJ photographer and director David Patiño to put the K-1 through its paces.
Like Ricoh’s approach to medium format, the K-1 carves out its niche as an ultra-rugged camera that packs more than its fair share of technical goodies for the price. The world has known a full-frame Pentax DSLR was in the offing since 2014, but it wasn’t until 2016 that the long-awaited K-1 arrived.
