Agreed, but the idea that you don't have to do that is the draw. Also, the car thing was just an analogy to represent the user experience. I am interested in your power assessment to save one photo. Maybe the lever would be simple to prime the shutter. There is plenty of space for solar panels on a camera that does not have a rear screen. Maybe you will just have to let it charge the capacitor which just holds it there in case it's ever needed. IF the battery dies and there is no sun, well then you are probably not taking pictures anyway haha. When the sun comes out, you are good to go. If your battery dies and you can't charge it and you want to take photos, you can work with this limitation and still have a camera. Seems good to me. Also, I have gone on many canoe trip greater than a week. There is much less room for non-essential items that you would think. Maybe id never use this function, but to know I could would be great. Not having AF in this mode and having to wind the shutter would keep you from overshooting. I think it would be a very cool feature to add. I mean, we are always adding new photographic features that sound pretty cool but no one really uses, but what about adding a user experience feature for a change?
