EVF
The Tru-Finder
™
electronic viewfinder
delivers class-leading viewing ease thanks 
to sharp 1440k-dot (SVGA) resolution, a 
23.1mm eye-point, and a notably wide 
31.9° viewing angle that leaves competing 
optical viewfinders behind. A 100% field 
of view combines with faithful effects 
previews to ensure that what you see in 
the viewfinder is exactly what you see 
in your photos and movies. So you can 
fine-tune every aspect of your image with 
confidence and achieve desired results. 
On-screen displays keep you informed 
of current camera settings. 
Effects previews
Unlike optical viewfinders, Sony’s Tru-Finder
™
electronic viewfinder
displays exactly what will appear in your photos and movies, 
including the effects of exposure control, white balance and 
creative styles—as well as background defocusing if you press 
the Preview button. These capabilities are made possible by 
Translucent Mirror Technology, which enables real-time viewing 
of the image captured by the image sensor at all times. 
Adjustable eye-point
Two finder magnification ratios are selectable, allowing you to switch from the default 
(max.) mode to the standard (lower ratio) mode to support an extended eye-point. At the 
maximum 23.1mm eye-point, the entire frame is easy to see even when wearing glasses.
