What I really need now is a compromise. I want the freedom of my own digital darkroom but I need a fully manual and digital camera with an incredible 4-6 month battery life. So cut everything out of the camera that sucks battery - the LCD screen, the motors, just have the sharpest lens and the best sensor, bring back the optical viewfinder. In fact, I wouldn't even mind having film as a backup, in case the battery runs out.
Sure this will add a bit of weight and all that, but this will appeal to those photographers who love the process, and believe that the end result takes care of itself. I can't help but draw parallels to programming but I'll refrain from doing so.
Being at the right place at the right time, perhaps takes a week of backcountry hiking, so be it. I need a camera that doesn't run out of juice, and has zero lag, for that once in a lifetime shot.
On similar lines, we have auto focus and manual focus, 2 extremes why not a middle ground, assisted focus ?. Nikon AI and AI-P lenses had this ideology, but surely that didn't survive.
