On the last day at Svalbard I joined a snowmobile hike to the East
coast of Spitsbergen, a 10 hour ride. I carried the 645D in a
holsterbag (a LowePro Toploader) on my chest. The temperature in
Longyearbyen when we started was -25 °C. I could swear it was colder
on the glacier.
In short, the camera performed flawlessly. Exposures turned out
correct, the AF was snappy and accurate, processing and storing to
memory card worked at normal speeds and without glitch. All buttons
operated as they should.
There were some gotchas, though, but hardly the camera's fault.
1. The LCD on top of the camera got veeeery sluggish. When changing
shutter speed with the control wheel, for example, it took about five
seconds to switch the displayed number.
2. All of the manual focus 645 lenses and many of the FA lenses are
constructed in the same way as are the A-series for K-bayonet. That
is, with a lot of metal. This means one has to be careful about
handling the lenses with bare skin. Any amount of moisture will freeze
on touch.
3. The glass on rear display also gets very cold. My nose stuck to it
twice. The skin is still sore, two days later.
Cath came in and asked what I was choking over.......
Sorry.
4. Battery performance goes down. Mine was fully charged in the
morning. By lunch I had made about 100 exposures, and the indicator
showed 67% charge. Some time in the afternoon I tried to do a series
on passing snowmobiles. The indicator dropped to empty after five
shots, but all images were stored correctly. I tried again with eight
exposures twenty minutes later, and everything still got stored
properly. The indicator would go back to 67% after a couple of
minutes' rest in the holsterbag.
Oh, and _don't_ breathe out with the camera before your face! :-)
