    Then buy the RF 35/1.4L VCM.

    I'd rather have a f/1.4 lens that is smaller, lighter and cheaper.

    The benefit of BSI decreases with increasing pixel size. Below 2 µm it’s evident, above about 4 µm it’s minimal to none. The driver...

    What about pneumatically or hydraulically in- and -deflatable lenses? I'm sure he has already developed them in his secret laboratory...

    What they need is something like SA on the RF macro, but it changes how the image is corrected while increasing or decreasing the mass...

    I don't know enough scientists to know, but I do know one thing - many scientists with bias towards an outcome will report findings that...

    My experience is that to judge the AI output you need to have a certain level of knowledge to start with - which is why I posted the...

    Can you include the equations as screen grabs? There should be other methods, eg calculating the size of the rectangles and then doing...

    Always show your working is what they say in exams - which is why I screen grabbed the equations.

    Possibly. We're being asked to accept that 19.96 is ok. Why is that number ok and not some other number? Where is the limit on what's...

    And now back to the distortion correction debate!

    My experience of using the R7 extensively for a couple of years is that I can go up far higher than the iso 2000 that you concluded...

    I usually guess and call it an L or not. sometimes you can gather the intent and if Canon would slap the L onto the lens, and sometimes...

    Back-side illumination has been the only architectural improvement to imager sensitivity since gapless microlenses.

    Can anyone explain why the R100 can't use the RF extenders?

    Can somebody please explain why the patents often include the 'L' designation of the lens? I mean, the 'L' mark is rather a marketing...

    the embodiments are not usually drawn to scale at all so I presume there's just less empty space. I was a little surprised by the lens...

    Yes, but conversely, those lenses and a bazillion more lenses get added onto the Fuji side if we do that. It would honestly look far...

    Maybe the difference stems from your using square pixels of finite size rather than inifinitesimal steps of size tending to zero. Your...

    I think it's not fair to exclude Sigma Tamron lenses for the ecosystem comparison. They are making RF-S so much more attractive and...

    In this patent application (2026-004077), Canon shows off an embodiment of the fabled unicorn lens for the RF mount, the Canon RF 35mm...

    Thanks for the explanation, Richard. I had kind of forgotten about the 12-bit readout. If the Sony sensor actually reads out 14-bit data...
