I'm just a nerdy middle-aged guy who likes foxes, pikas, and marmots. I'm starting to branch out into photographing people; that may sound a little odd, but I've spent so much time photographing animals in the wild that photographing people in a studio takes some adjustment.
If you can't tell by my images, I have a fondness for the smaller animals, particularly the ones at high altitude (pikas, marmots, weasels). Nothing wrong with elk, moose, and bears, but it's the little guys I'm drawn to when making images.
I made the switch from DSLRs to mirrorless: i'm now using a Sony a7Rii and a7ii as my primary cameras, and a Sony a6000 with some native E-mount lenses and an adapter to continue to use some of my A-mount lenses. I still have a DSLR, but I can't remember the last time I actually used it.
Since Sony doesn't have any long, fast glass for the E mount (ahem . . .), I'm using adapted Canon mount lenses with adapters - a Canon 600mm F/4 IS with a Metabones adapter, and a Sigma 120-300mm f/2.8 with the Sigma MC-11 adapter.
A few years ago, I did a brief write up in Outdoor Photographer.
