I have , for a long time , been under the impression that SLR cameras capture the exact image seen in the viewfinder. I'm finding for some reason that this is not the case with digital. Also, I'm not so sure it was the case with my Minolta 700si 35mm film camera. On the Sony A550, the processed image, is larger than the image seen in the viewfinder before the shot. In other words, if I put the edge of the frame in the viewfinder, on a lateral line and then snap the shot, the processed image overlaps the line. This is hard to explain. I'm wondering if there is a setting that allows to capture the exact image seen in the viewfinder????? I've noted that when I change aspect ratios and megapixels, this does change some but it is still not the exact image seen in the viewfinder. Anyone?
