In the literal sense, yes, sharper, but perhaps that’s partly due to the iPhone I’m using.
I suspect that if I attempted the same stuff using my D200, it would look a bit less crisp; that’s probably something I have discovered using my old manual Nikkors: maybe they don’t calibrate accurately with the viewfinder screen. Having said that, if I am actually missing focus with them, it might be because with my analogue Nikons I had the great advantage of a split-image screen in the pentaprism. Checking a silly little focus light isn’t a brilliant technique, and very distracting. Frankly, having made use of it on tripod-based shots, it’s disconcerting to see just how vague an aid that light actually is in practice. I think I remember everything being better on the D700, but that’s now a lost cause. I loved that camera. ;-(
However, it’s really been the iPhone that’s got me back snapping; I had pretty much given up carting a heavy, dedicated camera with me when I went out of the house.
