I've been wondering for a while at which direction canon is going with the newer STM tech lenses. I really can't say anything negative on how the STM lenses perform but there are advantages to the older USM lenses. Such as ring able to focus the lens without power. But then, I'm not sure exactly which is better per se. Maybe you guys know about this? Will we see L glass with STM?? Or is it just an "APS-C" thing. Maybe we'll see dual pixel af thing in all future camera bodies thus STM L lenses? Maybe this is too vague/not important. Opinions? Know-abouts?
So tell us, how well does your digital camera work without power? None of mine work at all.
