Just put my Pentax K-1 up for sale on eBay. Offering three extra batteries and a weatherproof remote as part of the package. I need to stay with one camera system and that will most likely be Nikon. I have owned most over the years.
As a landscape photographer, it is hard to part with the K-1; it is the ideal DSLR for landscape photography with its 36.4 mp sensor. It also offers astrotracer, which most other cameras in its class do not.
On to using an older camera, the Nikon D810 as the primary camera. Will need to sell my Pentax 28-105 zoom lens and my Really Right Stuff L-bracket.
The life of a photographer; expensive hobby and ever-present change.
