Sony appears to have borrowed elements from a variety of models - Alpha DSLRs, the RX1, NEX-7 - when designing the 7 and 7R. The build quality is very high, with a magnesium-alloy construction enabling dust and moisture resistance. A built-in extended grip makes the cameras comfortable to hold even with full-size A-mount lenses attached. There's a super-sharp XGA OLED electronic viewfinder with accurate depth-of-field reproduction and a manual-focus zoom function, along with a 3-inch 1.23M-dot LCD that tilts up 84 degrees and down 45 degrees, letting you frame shots and verify exposure from below or above eye level.
