Sony's 1500C and 1000C are low-end products of Sony professional machines, and 1500c is a machine that replaces 1000C, because 1000C came out too early. In fact, 1500C is also Sony's money-making machine, but 1500 is a card reader, and the future will be the era of card machines. In low illumination, 1500C is better than 1000C, but some users who use tape drives are afraid of the insecurity of using cards. In fact, it is necessary to worry. After all, people get married once. Therefore, I support the card machine. As for 1GK, I think it is also a substitute, replacing MDH 1 machine, but if it is a wedding, I still choose 1500C. In my humble opinion, my predecessors laughed.
