Here's a list of some camera features I'd love to have – all of them doable in firmware, so it's basically a free-for-all smorgasbord of ideas for camera manufacturers.
I supported a Kickstarter project where two guys are building an affordable large format camera, and soon I will own a 4x5 camera. That has raised quite a few questions.
I have always been a fan of Sigma lenses, and the Japanese manufacturer's latest initiatives have just made me a bigger fan. Sigma does everything right these days.
