    I had ChatGPT make a similar drawing (to scale) and subsequently calculate the percentage of the area of the dark corners and the result...

    Interesting. I assumed that PowerPoint can correctly draw shapes of the sizes I input, and that PhotoShop could correctly count pixels...

    The Otus RF lenses are MF. The Milvus are also MF.

    Purist here 😆 What would be the point though? apart from price maybe? But TS lenses are niche lenses so I'd assume not too...

    A MFD of 20cm would be the same MFD as the RF 20mm f1.4 L VCM lens.

    Hello everyone. Ever since getting the R6 Mark III about a month and a half ago, I've been having this problem happen with close to 100%...

    Canon could have used the M100/M200 body as the basis of a fixed-lens compact camera, but it will apparently never happen.

    I think the AI isn't able to decide what is misinformation, so if someone posted wrong calculations on a forum...

    Gimme 1/500s flash sync w/ EFCS and I will be super happy. It does 1/320s now so not a massive leap. AFAIK, the only thing that will...

    It's also apparently looking like an F/5.6 to F/6.3 lens now as per latest information... instead of F/4, F/4-F/5.6, constant F/5.6.

    I had checked it with ChatGPT, which gave ~1.4%. I wonder what is going on?

    When it's routine calculations they are very good. When there is proper on-line documented information, like say government websites on...

    Incidentally, maybe Gemini did get it wrong. I took a pragmatic approach rather than a mathematical one, made a circle with a diameter...

    Do Zeiss Milvus (and Otus) RF/EF mount lenses have AF?

    Rotation could be encoded, too, right? The position of the sensor relative to the image circle could then be calculated, and since DLO...

    I napkin'ed mathed it out to around 20cm. i could be mistaken though.

    99cm length is far too big, even for my largest backpack! :ROFLMAO:

    depends, you'd have to restrict the movement, you couldn't, for instance, shift in different angles - you could only move up and down...
