In reply to Juliankitesurfer:
I think that what you are after does not exist.
I use two small cameras, a Fuji XF10 and a Fuji XP200.
Using both with gloves, especially when it is cold, is difficult.
However, it is made slightly easier by sticking some self adhesive rubber pads to the power button and shutter release.
I tend to use the 'auto' setting to make things easier.
I only shoot jpegs and I think that my results are okay, but not outstanding.
It amazes me that some people get great shots in difficult situations with everything from monster full frame cameras to phones - I'd like to know what their secret is?
