    Of course I understand, and I'm also taking the comparison to the other extreme. It just seems to me that Canon is exaggerating the...

    If they made a 28mm pancake with weather sealing I'd be so all over that. The weather sealing + size combo would make every other...

    Ah, in which case... you know! Enjoy.

    ?? Why are you blaming Sigma?? Sigma would happily sell their FF AF lenses to Canon RF users, if Canon would have allowed that.

    Nice… but sadly not relevant for us :(… And isn’t the flagship the 35mm f1.2?! I’m really really jealous of the the E-mount! I m...
  • DocInfoSci
    Yeah, totally agreed. But it weirds me out that it never got bumped to the R6 line where it seems to make good sense for still life and...

    The RF lenses I pointed to are for lenses I would not have if I sold 1999-2005 EF lenses by 2017 & for focal lengths I never had in the...
  • DocInfoSci
    Yours is an awesome reply. I'd love more like this. For family and friends doing typical family and friends things, I still thing all...

    Just to drive @scyrene's point home, a 600mm f/5.6 needs the same size front element as a 300/2.8. A 600/5.6 would also need more glass...

    Oh, man -- that's a can of worms...

    The benefit of the short 20mm flange distance is most significant for wide-angle lenses. For lenses like my TS-E 17mm f/4L or EF 14mm...

    "no word yet on an L-mount or Nikon Z-mount version of this lens." (Sarcasm) If Nikon is blocking this third-party lens, everyone...

    Good question! I hope that reviews will give us an answer! Canons 3rd party politic is recently supporting Zeiss as they are the only...

    Not necessarily, it depends on the mass of the lens group used for OIS ! And don't forget the Leica SL AF lenses, did you ever test...
  • AlanF
    Agreed for uwa lenses. In practice, this is true for up to 35mm focal length, fading to hardly any difference at 50mm and all gone by...
  • S
    Oh dear. Are you deliberately missing the point? Why fixate on 400mm when we are discussing a lens that goes to 600mm? Hint: f/5.6 is...
  • Etnaphele
    But are they really so perfect? The tests of the 50mm were pretty underwhelming last year (LoCa is one flaw I remember). I see the point...

    The 2024 EOS R1 and 2024 EOS R5 Mark II do not use "Sensor Shift" (IBIS High Res) to create extra pixels. Instead they use a Neural...

    Non-sense: 1200mm is a "special" lens that sells close to zero. 400mm is a normal tele focal length.

    I've played with the in-camera upscaling as I feel like I was probably the only person on earth who used the IBIS-operated high...

    The Zeiss Otus series are close to perfect ‘optically corrected’ lenses. These have all metal tight tolerance construction. The...

    Full-frame Canon 3rd party RF autofocus lenses? They would need a damned good lawyer!
  • roby17269
    But then it would not be available for RF...
  • Malm
    Well, that can be, but can I attach that 'impressive' new Sigma lens to my Canon camera? Maybe with superglue :cool: The usual -...

    What size is the image circle?
