Sent by a reader: Nikon D850 at the North Pole
I went to the North Pole with Polarexplorers a company that does this sort of thing, we landed at Barneo ice base
that is really something, every year a Russian company sets up the base for a month tarting with parachuting a small team to clear a runway north of 89 and then the bring in other people and set up camp. People then shuttle in and out with a Russian AN40 STOL aircraft (see pics and movie which is frame two of the FLICKR) after that others arrive including me, some ski the lsast degree from 89-90 and others like me hop on the helicopter for a short flight to the Pole and to take it in.
The ice this year is thin- the season this year for the camp was only a few days more than 2 weeks and even with that the runway cracked. This is the Arctic Ocean, there is 10,000 feet of water under the ice, the ice is moving constantly cracking and forming pressure ridges (seen in photos) - All of the scientific measurements appear to indicate this is the thinnest ice and warmest Pole on record. It is still cold (-23 when I was at the Pole), but relatively it is much warmer and the ice much thinner. That picture file has a bunch of satellite data lifted from various government web sites for the day I was there showing how thin the ice was.
There are amazing Youtube on the Pole and Barneo ice base especially plane landing and treks to the pole if that interests you. A quick search brings it up.
As for the Nikon, I found the camera was a champ in the cold. I use a fixed lens, in this case a 50 mm F1.4 Nikon on the theory that a fixed lens seals the camera better than a zoom. I had extra batteries in an inside pocket something I learned from other arctic trips- like the 2015 total eclipse in Svalbard at 79 N (photos there too if you wish- that was a D810). I use heated liner gloves because cameras are too clumsy with down mittens- that works great even at -23. But I didn't use my extra battery the EL-15a functioned well and I shot a normal quantity of photos without switching batteries- I did not experience the rapid LiON cold death I have seen with prior versions of the battery.
I also use my D850 here in Tucson at more than 100 degrees and getting warmer- it works well there too. You have written and linked much about the camera's abilities- but I also think the cameras environmental tolerance is great with it functioning perfectly from the North Pole to the desert.https://www.flickr.com/photos/eliot_photos/sets/72157665994144247/
Not all pictures are from the D850 - there are some Nikon point and shoot as well but most are the D850 - few are HDR I shot because the dynamic range of all white is a problem so HDR does indeed help a bit.
