I love the optical view finder, the day the EVF become standard (as they have been talking about) i will be disappointed.
The day EVF becomes standard it will be so brilliantly refined, configurable, fast & flexible we'll wonder how we ever coped with those old optical viewfinders. True, they're not there yet. But look to the quality gains in the past few years...
When peerless quality EVF eventually beds in as as the industry default, that will be the death knell of the current DSLR form factor with the bulky prism & mirror with its associated shortcomings and constraints.
Maybe there will be a hybrid rangefinder for the nostalgic photographers among us. Oh wait, it's called the Fuji X100!
Yet there can't be too many people mourning the photographers black cape disappearing into history, or the waist level finder on a twin lens or Hasselblad? Or assessing overpriced Polaroids on commercial jobs vs tethered shooting? And what of the few still carrying the torch for film or handheld light meters? Bless their little cotton socks.
Like it or not, eventually it will be the same with the current optical prism finder. Consigned inexorably to history.
