Pentax K-1 Mark II Announced | ISO 819,200 & Hand-Held Pixel Shift

By Holly Roa on February 23rd 2018

While often overlooked, Pentax is still out here plugging away, making impressive cameras and quietly out-innovating Canikon. Pentax introduced their first full-frame DSLR, the K-1, in 2016. The K-1 offered 5-axis in-body image stabilization and enhanced resolution via Pixel Shift technology, the latter only usable when mounted on a tripod. 

Now, the K-1 Mark II has been announced and will offer modest, though useful performance boosts, mainly via a newly added ‘accelerator unit,’ which makes improvements on the camera’s signal-to-noise handling. Notably, the K1-Mark II gets a two-stop bump in native ISO capability, increasing to 819,200 from the K-1’s 204,800, and technology advances have allowed the new camera’s Pixel Shift feature to be used while hand-holding. 

What’s interesting about this update is that it can be installed into pre-existing K-1 bodies. For $550 USD or $690 CAD, K-1 owners who ship their cameras into a Ricoh service center between May 21st and September 30th will receive an upgrade via hardware modification to turn their camera into the new Mark II version.

While not exactly an action shooter’s body its 4.4 FPS burst, the K-1 Mark II and its predecessor are pretty cool cameras, offering up features that aren’t found in other DSLR bodies. Pixel Shift Resolution does make a noticeable difference in detail captured, as seen in the 100% crops below.

    Nice upgrade.. but more than this new features we needed a bigger buffer and some AF-C improvements..  what happened with that??

      I too would have liked to see a bigger buffer, and maybe a better battery, but alas, this is only a 2-year update, so it’s like an “s” update for Canon / Nikon. (Although ironically, a buffer and AF upgrade was sometimes the most you’d get out of an “s” upgrade from Nikon!)

      Speaking of AF, I thought I read somewhere that this K-1 mk2 DID get an AF algorithm upgrade, even if the AF module itself wasn’t brand-new? I’ll have to re-read the press release.

      Definitely eager to get my hands on this bad boy for a landscape photography review!
