What's the point of optical viewfinders now?
Sep 13, 2009

The only reason I have ever used the optical viewfinder on my DSLR is when sunlight washes out the liveview. Is there any other reason to preserve them? Reasons not to:

1. They require a mirror in the light path, which adds bulk, noise, and lag to the camera. Not to mention complexity since you then need a second image sensor to support liveview!

2. With liveview it's possible (though regrettably not yet common) to add exposure preview and probably other features I haven't thought of.

I see Olympus and Panasonic have started in this direction with some of their micro-4/3 cameras. But I don't understand why there aren't more options like that -- particularly with larger, faster sensors.

As for the sunlight visibility problem: If the state-of-the-art high-res LCDs aren't bright enough, at least Sony can produce OLED displays in this size now.
