Ricoh USA/Europe have announced a rather unique upgrade service for owners of the original Pentax K-1 DSLR - they will replace the camera's main circuit board and the logo on the front, and voila, you have yourself a K-1 Mark II. 

Could this be the future of high-end cameras, where the body remains the same and the "brain" is swapped out for a more capable version? Or is it merely indicative of the small number of changes that Pentax have made in the 2 years since the original K-1 was launched (the more cynical view)?

The upgrade service will cost $550USD / $690 CAD / £450 and be done for a limited time from May 21, 2018 – September 30, 2018.

Canon today announced they have reached two major production milestones — a cumulative total of 90 million interchangeable-lens EOS cameras and 130 million EF-series interchangeable lenses. The EOS 5D Mark IV (pictured) was the 90 millionth EOS Series camera range to be produced, while an EF16-35mm f/2.8L III USM became the company’s 130 millionth interchangeable lens. Canon’s EOS system debuted alongside the EF series of interchangeable lenses in March 1987 as the world’s first fully-electronic mount system for film AF SLR cameras. Over the years, both product lines have continued to expand, gaining support among users ranging from first-time users to professionals. Production accelerated in the early 2000’s with the spread of digital SLR cameras. Canon’s interchangeable-lens digital cameras have maintained the No. 1 share of the global market for 14 consecutive years since 2003.

DxOMark have released their detailed findings on the Nikon D850-'s 45.7-megapixel full-frame sensor, which has become the first DSLR imager to hit 100 points on the DxOMark Sensor scale. "The introduction of the first BSI sensor in a full-frame Nikon DSLR with a super-high 45.7Mp resolution puts the Nikon D850’s image quality on par with, and often better than, medium-format cameras," the company says. "The first DSLR to hit 100 points — rather apt for Nikon’s hundredth anniversary year — puts the Nikon D850 in a class of its own for image quality."
