Canon has done a lot to change the photography industry, but one of their most revolutionary moments in the 35mm SLR market came with the AE-1. One of the best-selling cameras ever (with estimated unit sales in the millions), the AE-1 was the first 35mm AE SLR with shutter speed priority, TTL metering, and a Central Processing unit, making the camera hugely appealing to amateurs and the general public for its ease of use. The camera was in production for seven years--that's an eternity in the context of the modern product cycle and a testament to its popularity and its dependability.
Given how many AE-1’s were sold, it’s no surprise that there are plenty of used models around that are in great shape. This manual focus camera has an FD mount, so if you have any older Canon lenses around, you’re golden.
