The table

Model Full frame (36 x 24 mm) or Super35 sensor size (25 x 19 mm) Hasn’t got a rolling shutter problem RAW/log mode 4:2:2 Useful also as shouldercam Real viewfinder Can be wifi controled with Android tablet Price Lens mount Built-in ND filter Ultra fast smart auto face-detection-real-time-tracking focus pros & cons
Canon 7d close to Super35 (22.3 × 14.9 mm) CMOS false 6s quasi-raw with firmware change false false false false (but there is usb way) good Canon EF/EF-S false In your dream old, can’t really be considered HD (due to crappy h.264 recording format), no canon audio inputs.
Sony Alpha a7S full frame (35.6mm x 23.8mm) false S-Log2/3 Not internally, 4k 4:2:2 via hdmi false false true, untested good E-Mount false unclear Really decent picture when downscaled to HD and shot with S-Log3


RAW/LOG MODE must also define what kind of color profiles/luts are available with camera (No, i will not google for your crappy luts).
