The Canon AE-1 with shutter speed-priority AE and TTL metering became wildly popular in Japan and overseas.
However in a few overseas markets, the AE-1 had a high price tag. There were also many users who still preferred manual metering. In response to these people, the Canon AT-1 was developed. It had the same body as the AE-1. It featured match-needle metering and TTL center weighted averaging metering with CdS photocell. The camera could use the same accessories as the AE-1.
