Last year I shot the Sony A7 in a Nauticam housing (review here). It seemed like it might be the future realized: a full-frame sensor, mirrorless camera, full of the latest technological advances. There was a huge buzz and it looked like it really might be the advanced photographer’s dream system; powerful, small and light with all the quality, sharpness, low-light and dynamic range (shades of color, particularly in the highlights and shadows) capabilities that a full-frame camera brings to the table.
