Originally posted by bdery 3-use "whole hand" biking gloves. Not as warm, but warm enough for short outings, and with good grip usually.
That's my glove of choice when it gets to be below 0c (32f). These will typically keep me warm to -20c (-4f) and beyond. It also helps that I'm usually biking when I'm out taking pictures
If it gets colder than that, then I wear one Carhartt winter work glove on my left hand, but I still use the cycling glove on my right for operating the camera.
I don't know about other Pentax cameras, but the K-7 is surprisingly easy to operate even with big gloves on. I've done it with both hands covered in thick winter gloves. I have to be a little more careful about pressing single buttons, but I've never accidentally deleted an image or anything.
