We checked out Sony's stunning Alpha A7 full-frame mirrorless camera at their recent dealer show in Toronto. Merging the best aspects of the compact NEX line and the high-end full-fram Alpha line, the A7 is reasonably compact but features a 24-megapixel full-frame sensor and will shoot sensor-cropped images with NEX mount lenses. Sony is coming out with full-frame lenses to complement the Alpha A7. The more expensive A7r has a 36 megapixel full-frame sensor, it is geared towards photographers who print large-format work.
