Ricoh Imaging’s Pentax K-1 Mark II. which was announced just before CP+, is scheduled for release in Australia next month, with pricing to be announced next week.

Physically, the ‘full frame’ K-1 Mark II is almost identical to its predecessor. It has the same 36.4-megapixel CMOS sensor and PRIME IV processing engine, which includes AI-based Real-time Scene Analysis. It also effectively compensates for distortion, vignetting and chromatic aberration using data from compatible D FA-, DA-, DA L- and FA-series lenses. Sharpening is also adjustable via Fine Sharpness and Extra Sharpness functions. The sensor sports an AA (anti-aliasing)-filter-free design to optimise image resolving power. Users can select an AA filter simulator to minimise the effects of moirø© and false colour by using the camera’s SR mechanism to apply tiny vibrations to the image sensor during exposure.
The camera’s SRII Shake Reduction system supports five-axis stabilisation, with up to five stops of correction available. Other features carried over from the previous model include the SAFOX 12 autofocus mechanism with 33 autofocus points, dual SD card slots (UHS-1 only), 4.4 fps burst speeds for full-frame files (6.4 fps for APS-C crop files) and the Flexible tilt LCD monitor.
Like its predecessor, the Pentax K-1 Mark II is made with a magnesium-alloy body that Ricoh claims is dustproof and weather resistant. It also has the same compact white LED Operation Assist Lights, which make it easy to change lenses, swap memory cards and adjust back-of-camera controls in dimly-lit environments. Also carried over is the Smart Function dial that allows photographers to easy select frequently-used functions without going into the LCD menu. Video recording is limited to full HD with 1920 x 1080 resolution, although 4K resolution is available with a new interval movie mode.
The updates that define the new camera are entirely internal and include a new ‘accelerator unit’ pre-processor, which improves high ISO noise performance and raises the top sensitivity to ISO 819,200. An advanced Pixel Shift Resolution System II, which utilises the capabilities of the SRII system, enables users to record images with minimal moirø©, increased sharpness and overall high quality. It captures RGB colour with each pixel, delivering what Ricoh describes as ‘significantly finer details and truer colours’. A new Dynamic Pixel Shift mode captures four images in quick succession and combines them, eliminating the effects of camera shake to produce high-resolution photos when the camera is hand-held.
Autofocusing performance has been improved through revised algorithms, which support faster, more precise focusing from the activation of the AF system to the capture of the subject. Tracking AF has also been improved, through the Real-time Scene Analysis System. The K-1 Mark II provides a wide range of customisation settings, designed to expand the functions of the USER Mode and the Fx (function) buttons, improve accessibility to desired functions on the control panel, and prevent accidental operational errors.
Because almost all the improvements in the Mark II are firmware-related, in the North American market, Ricoh Imaging is offering an upgrade program for owners of the original K-1 camera that will allow them to have their camera ‘converted’ into Mark II specifications. The service costs US$500 or CA$690 and requires the circuit board in the camera to be swapped-out and replaced. We don’t know whether this service will be available in Australia but will update this announcement with pricing and other information when it becomes available.
Pentax cameras are distributed in Australia by C.R. Kennedy & Company. For more information, visit https://pentax.com.au/.
