In Part 1, I talked about the effect of cold on Nikon D800 bodies. Today, the focus is on lenses and remote shutter release cables. Cold, frost and wind affect my camera equipment and accessories.
I use three Nikkor lenses with D800 bodies. Focus is manual and done on infinity stars. With the 14-24mm f2.8, once the focus is done, I can tape the focus ring and I am good for the night (week). I haven’t seen any shift of the focus due to cold. I love shooting at 14mm to get as much aurora as possible in my pictures.
This is another story with the 24mm f1.4 and 20mm f1.8. These are beautiful fast lenses but more difficult to focus -especially the 24mm. And the focus keeps shifting as the equipment gets colder, when the wind picks up… Protecting camera and lens helps but one needs to keep checking for sharp focus.
Frost on the front glass of lenses is also an issue. Protective filters are removed when shooting aurora borealis. Once there is frost on your lens (don’t even think of breathing close to your lens…), it is best to pack it and wait for the frost to melt before cleaning the lens to avoid scratches.
Batteries in wireless remotes die quickly so I use a cable shutter release (MC-30). The cable plastic hardens just below 0°C and becomes brittle, exposing wires. As with other equipment, preventing damaging by protecting cable shutter releases is best. A spare cable shutter release is highly recommended.
