Why is the second-hand Canon m3 more and more expensive?

Market demand increases and products are scarce.

1, product scarcity: the number of camera models in the market is limited, cameras are favored by collectors and photographers, and the price will rise.

2. Increased market demand: With people's increasing interest in photography, the demand for second-hand cameras increases. Second-hand Canon M3 cameras are in short supply, and prices will rise.
