Pentax K-1 Mark II: Ricoh renews its flagship, now up to ISO 819,200
The machine uses the same 36.4-megapixel full-frame CMOS sensor assisted by the PRIME IV image processor, but puts a new acceleration unit between them: Pentax has succeeded in expanding the ISO range to the value of 819,200.
Pentak K-1 was one of the most anticipated products of 2016, and the reason is soon said: it represented the entry of the historic Japanese brand in the world of Full-Frame digital SLR cameras. The launch was a bit troubled, with announcements and delays, but eventually came on the market, with the cards in order to satisfy all the Pentaxians waiting for a body able to make the most of the optics born for DSLR cameras. 35mm film. Now Pentax-Ricoh announces a successor for this product, the new Pentax K-1 Mark II.
The machine uses the same 36.4-megapixel full-frame CMOS sensor assisted by the PRIME IV image processor, but interposes a new acceleration unit between them, which probably works in a similar way to the LSI co-processor used by Sony in the last mirrorless. This pre-processor should be able to improve the signal-to-noise ratio.
This is not new for Pentax, which uses similar systems on the APS-C as K-70, but at the time of the first K-1 there was not a unit suitable to help in managing the amount of data coming from the 35mm sensor from 36.4 megapixels.
Thanks to the integration of this unit Pentax has managed to expand the ISO range up to the value of 819,200, a big jump compared to the 209,400 ISO available on the model before the maximum sensitivity item. The price to pay for the integration of the co-processor is a higher-energy consumption, which decreases the autonomy from 760 to 670 shots.
The sensor is mounted on a 5-axis stabilization system and in addition to the stabilization, tracking asters, simulation of the anti-aliasing filter adds a new feature called ” Dynamic Pixel Shift Resolution “: in practice with this mode, you can use the function Pixel Shift Resolution System, which combines 4 shots to create a unique high-resolution image by moving the sensor one pixel at a time, even freehand without the aid of a tripod.
The body of the machine continues to be weather resistant, offering a pentaprism viewfinder with 100% coverage (0.7x magnification) and a 3.2″ articulated display and 1.04 million dots.
It updated the autofocus algorithms of the previous 33-point system (25 cross) to offer better performance in tracking modes of moving subjects. The burst has not been updated and continues to settle at 4.4 fps.
