    Cool. This is the lens I wanted nine years ago when I bought my Canon EOS 60D. No biggie, though, because Sigma made essentially that lens: the Sigma 18-50mm f/2.8 EX DC. I’ve moved on, but it’s about time that Canon think about good lenses for APS-C.

    The real question is when, and for what. They promised no new EF lenses for 2019… does that include EF-S. Or will this be an EOS R lens for the inevitable APS-C EOS R cameras coming … eventually?

    Agree, finally they are moving in right track.

    2 Dave Haynie:
    Its backfocus is very long (about 1.5x image diagonal) indicating a SLR lens, this rules out aps-c mirrorless.
