Sony A7R IV bulb This is a chrome HasselbladThe Sony A7R IV is a mirrorless camera with a 60mp full frame sensor and 5 axis stabilization built in, which is pretty impressive, I think. It shoots 4k video up to 30fps, and 1080p up to 120fps, with HLD and S Log2 & 3 support. In excellent condition, with under 1500 actuations. Charges via standard USB C or USB Micro cable (not included.) Includes battery and strap, though.
