Finally some interesting RF-S lens patents (EF-S 15-85 successor designs?)

    By image height, it looks like patent applications for APS-C lens designs:

    • 15-70mm F2.8-4 IS
    • 15-70mm F4 IS
    • 15-85mm F2.8-5.6 IS
    • 16-85mm F2.8-5.6 IS

    Unfortunately all of these are the kind that requires lens-correction at the wide end. But I guess I will have to learn to live with that ....

    digicame-info.com/2023/04/aps-c15-70mm-f28-4-is15-70mm-f.html

    Google translate:

    digicame--info-com.translate.goog/2023/04/aps-c15-70mm-f28-4-is15-70mm-f.html?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=auto

    Personally all three designs going down to 15mm in the wide end sounds interesting to me. I really hope one of these will materialize and end in front of my EOS R7.

    I'd love to see that 15-85 variant come to production...as long as it's a good lens. Canon needs to get serious about APS-C glass if they really want to sell the bodies.

    These would be interesting to see. Can't decide whether I'd prefer the 15-70 or 15-85, since the former looks pretty good at f2.8-4.

    In the meantime Canon Rumors is reporting an ultra wide RF-S is coming next. Labelled as CR2, so credible rumor: www.canonrumors.com/an-rf-s-ultra-wide-lens-is-next-from-canon-cr2/
