There are few things more photogenic than a winter landscape. Unfortunately getting that shot can be hell on a camera. And without good weather sealing, aspiring photogs risk permanently damaging their high-end gear.
Fortunately, every hardware manufacturer -- Canon, Sony, Nikon and Fujifilm -- has extensive catalogs of weather sealed DSLR cameras. While these offerings aren't necessarily waterproof -- you don't want to submerge them in the ocean by any means -- they're highly resistant to the grime, condensation, and freeze that you'll inevitably encounter as you hike up the Patagonia Mountains to claim that perfect shot.
First up is Canon's EOS 5D Mark IV, the latest offering in Canon's 5D series, which has full-frame lenses. In other words, it's a camera for the series photographer, the sort of individual who's extremely serious about her hobby or on the verge of being a professional. The 30.4-megapixel Mark IV differs from its 5D compatriots in that it has a higher resolution, a lighter weight, and an advanced autofocus system. Specifically, autofocus is faster than in previous models, and is sensitive enough to handle low-light environments. It also has burst shooting at 7 frames per second (fps).
Next up is Sony's full-frame DSLR camera, the 42 megapixel a7R II. It has 5-axis image stabilization so you shouldn't have any trouble shooting objects in motion, and it has full 4K video recording. Like the aforementioned Canon, the a7R II also has a speedy autofocus algorithm, so it can focus smoothly on subjects, no matter what the situation or the lighting. And it has burst shooting at 4.9 fps.
Not to be outdone, Nikon has its own weatherproof DSLR offering: the full-frame D850. This 46-megapixel camera is known for its speed -- a quick-shooting camera that can sustain bursts of 7 fps. It also has full autofocus capabilities, imported from Nikon's sports cameras. That means it's a high-performing camera in a wide variety of environments and situations.
Finally, Fujifilm has a medium-format DSLR offering, the 51.4-megapixel GFX 50S. In introducing a line of medium-format cameras, Fujifilm is showing its intent to go big, skipping a full-frame offering altogether -- which already saturates the camera manufacturing industry. Unlike the full-frame offerings, this is a large camera, yet it's not overly-heavy, so travelers shouldn't have too much trouble lugging it around.
