I use Sealskinz Ultra Grips as long as I can remember for any activity outdoors, from hiking, canoeing, abseiling, chopping wood to photographing and anything in between. They are great for temperatures between -10 and +10C when active in the outdoors as they are totally waterproof, have a warm merino wool lining, tough nylon outer shell, rubber dots for maximum grip (hence the name) and have great dexterity for handling cameras, lens changes and working those big buttons and dials on the Nikon cameras, etc.
Still have the older model but the new model has touchscreen tips which solves the one caveat I had with them, they are very tight fitting so taking them off all the time to check the iPhone was a pain. I had a little accident with a sharp knife while wearing them and cut my triggerfinger, the good part of that story was that I could now take the tip of my trigger finger off when needed to check for messages without taking the gloves off

Some of you will probably remember this image; me wearing the Low Alpine gloves while pretending to be a seal, and yes the other gloves would have been more appropriate name wise
