The storage mode of Panasonic HDC-MDH 1GK is card. Although it is a shoulder bar machine, it is very light.
Sony HVR-HD 1000C and 1000C are the same model (slightly different in front, one in SD and one in HD), but it is a traditional tape storage.
Finally, it is suggested that LZ use ... Panasonic HDC-MDH 1GK (more in line with the requirements of LZ).
If you want a two-seat system, you'd better buy the same brand and model. Otherwise, due to different machine brands or models, or different storage media (tape? SD card? ) and make the picture look obviously different: color temperature, sensitivity, etc. Compared with the color, it is still quite troublesome.
