We really didn’t know what to expect going into this. Panasonic hasn’t even made an APS-C body before, nevermind a full-frame flagship mirrorless camera. Though, it seems they realized the S1 series needed to make a splash if its release was going to trail behind Canon and Nikon’s first foray into professional-grade mirrorless cameras because the Panasonic S1R is massive.
This body is titanic compared to its competitors: the A7R III, Z7, and EOS R. Panasonic has decisively abandoned the notion that photographers want mirrorless cameras because of their reduced size and weight. The Panasonic S1R weighs in at 1.98 pounds. That’s about half a pound heavier than the Z7, or less than an ounce shy of the medium format Fuji GFX 50S! This camera is a beast!
