The Peace Baby Flex is a Japanese subminiature twin-lens reflex camera dating from the post-war era of small-format Japanese photographic production. It belongs to the family of novelty TLR-style "baby" cameras built around roll film smaller than 120, and was sold as an inexpensive entry into reflex shooting.

With only a single recorded UK auction hammer result — £1,700 in November 2015 — the Baby Flex sells for prices well outside the typical subminiature range, reflecting its scarcity rather than any everyday market level. As of today, no sustainable median can be drawn from one data point, so any estimate of what the camera is worth in 2026 should be treated as indicative only; further saleroom appearances would be needed to establish a reliable value band.
