Talk:Electronic viewfinder

Workable liveview has been implemented by Olympus E-330 DSLR before Canon

In fact it's already available compared to Canon's that is still to be released. I am much of a writer to change the page but I am bringing this up hoping somebody who could will.

Hybrid Viewfinders

Core distinction between viewfinder/display missing?

I read "It differs from a live preview screen in being smaller and shaded from ambient light, and may also use less power." but the actual difference is that you look straightforwardly at a preview screen while a viewfinder has optics that places the virtual image you are looking at at a significantly larger distance than it would physically be. This distance can be variable by using a dioptre adjustment, a common implement with viewfinders.

The old optical tunnel viewfinder common on non-SLR compact cameras, in contrast, does not use a screen and actually produces an (albeit rather compressed) 3D virtual image. SLR viewfinders instead go through a ground glass screen as a single 2D layer (for the sake of allowing to preview depth of field) and then, like with an electronic viewfinder, place this at some comfortable virtual viewing distance, possibly adjustable with a dioptre control.

At any rate, the main difference to an external screen (where the visual distance is your own choice) is that the view finder image is optically/virtually relocated to a comfortable (and often adjustable) viewing distance. — Preceding unsigned comment added by 2.244.87.219 (talk) 16:42, 25 February 2021 (UTC)
