    I don't care about digital sensor sizes. But I am a true believer of 6x6 negative film :). What else has there really been to recommend...
  • mangobutter
    ive seen the 100-400L II value spike back up after some decline, after canon announced they stopped making them. ive gotten some good...
  • DocInfoSci
    Totally agreed — it's been a game changer for my 300 f/4 + 1.4x and 2x extenders in the PNW forests. Figured I'd throw that out there...

    Canon's spec is with an f/1.2 lens (without a DS coating), yes. But even something like –4 or –3 EV is really dark...say a landscape...
  • DocInfoSci
    But that's for an f/1.2 aperture, right? Aperture limited scenarios, like lenses with a base f/4 or adding extenders, does reduce the...

    Im honestly very excited for this camera, MPEX shipped two days ago and will arrive today. But it was deff very tricky from canon to...

    Thanks guys. Yes, clearly not an issue..
  • neuroanatomist
    What do you mean by low light? AF sensitivity for current MILCs is below –6 EV (the R8 is –6.5 EV, for example). That light level is...

    Long overdue, I’m still confused why this wasn’t Tamron first RF mount lens first since it has no true direct competitor from Sigma (the...

    Not really an issue, since in low-light situations the aperture usually stays fully open.

    Nice addition to the endless sea of options but special in the standard zoom category! Just learning to like the EF-s 15-85 for time...

    neuroanatomist replied to the thread Canon Software Advisory.
    I did not get the email from Canon USA, but it's a legit issue and can be resolved by downloading the current version...

    Using Exposure + DOF simulation will hurt low-light AF performance, won't it? I've switched to having Exposure + DOF simulation as the...

    Did anyone else get this advisory from Canon about a Vulnerability in the Network Setting Tool? It looks legit but you always have to...

    Where did you get the "schematic drawing" for last couple of lenses featured here? Previously, they looked real and made sense. Just...

    I am using DoF simulation, having heard of it a bit lately... I works perfectly, focus is always where I want it to be.
  • neuroanatomist
    Somehow? According to Canon, focus shift is part of the lens design...it's not going to 'somehow be resolved' for the lens itself. Two...
