[Overall] Shooting information [SLR] Based on pre-exposure measurements only (selected exposure, AF mode, buffer size, battery capacity, etc.). The image in the viewfinder does not reflect the brightness, dynamic range, DOF, motion blur or color rendition of the recorded image. In difficult situations the photographer needs to record and image, examine it (most importantly its histogram), then if needed change some parameters and re-shoot. Additional information is available in live-view mode on the rear screen, but this defeats the purpose of an SLR body. [Mirrorless] 
Shows the exact rendition of the image: matching its brightness, dynamic range, DOF, motion blur and color rendition. Can blend in a real-time histogram and blinking highlights, which allow the photographer to optimize all shooting parameters prior to releasing the shutter.
