Ricoh FLEX7 is the most common and popular Ricoh Flex 7. Although it's not so famous now, it's probably the world's largest-selling dual-reflex camera. Take Minolta as an example, the most common one is probably Autocord, right? If these two machines are compared, Minolta will win in an all-round way. In fact, the evaluation of Minolta Autocord, which was also popular in that year, was second only to Luo Lai, and it was the representative of Nissan's double-reverse high-end machine. It is probably not worth a few dollars now, but the price at that time was more than five times that of Ricoh FLEX7.
Another common one is Minolta FLEX 3, which is contemporary with Ricoh FLEX 7. It was also a high-end machine at that time, and its performance and workmanship were far superior to the former.
