Image Quality Enhancements

The K-1 II's main addition is an 'accelerator unit,' which is a pre-processor that sits between the 36MP CMOS sensor and the PRIME IV image processor. Ricoh says that this pre-processor increases the signal-to-noise ratio, thus reducing noise, which implies it's a a noise reduction process. Ricoh told us that the accelerator unit, which was found on other Pentax models like the K-70, was not ready for the K-1 when it launched.

Thus, the company has increased the top ISO to 819,200 - a big jump from 209,400 on the original model. We'd be shocked if anything near that ISO is usable, seeing how the K-1 looked at 209,400 (hint: poor, like all cameras in its class), but we'll find out soon enough.

Ricoh says that 'deep blues' and 'lively greens' are more 'true to life,' as well.

The unit does put the hurt on battery life, though, reducing it to 670 shots per charge from 760 shots on the original K-1.
