A:AnswerI found that the sl3 has the aps-c sensor and that should work just fine with any cannon EF-S lens. Here's what I found.
Put simply, Canon EF-S lenses are designed solely for use on Canon APS-C DSLRs. Canon EF lenses are designed to work with full frame and APS-C DSLRs from Canon. Canon EF-S lenses have a smaller image circle that is only big enough to cover the smaller sensor found on Canon APS-C cameras.
