I'm very new to digital photography. I've basically been into pretty simple black and white film photography and only used cheap or old digital cameras that have been given to me as friends move on to the current latest thing. Recently, I've had the opportunity to "try out" a Nikon d200. Now, just walking around the planet, I see people taking pictures with their digital cameras NOT using a view finder but using the LCD/monitor. In fact, it appears that some digital cameras don't even have a view finder. Trying out the d200, I quickly realized that one does NOT have the option of using the LCD/monitor in "real time." And, I realize that it IS a SLR camera and the whole idea of the SLR is to see THROUGH the lens. But on the same token, I'm just wondering why Nikon does not allow one to see through the lense using the LCD/monitor.
