Here i introduce about this most feature the feature is Digital Preview,White Balance
with this features You can select between optical depth of field preview (which works in the normal way, stopping the aperture down while you look through the viewfinder) or 'digital preview' which effectively takes a shot without saving it and previews it on the LCD monitor.

I have great experience with this model,though a little heavy and hard to keep stable for long periods,the camera is very solid and dependable,I have taken it to Asia and on my fieldwork in Louisiana,It makes beautiful images,There are a ton of lenses to choose from. It is a great piece to earn on, though an expensive one with film and processing,this model is Affordable,Beautiful and opticsSolid metering.
