    Regarding EF lenses from the film era with strong distortion: I once had the EF 24-85mm/3.5-4.5 USM, with really strong barrel...

    You're right, scyrene, but I wouldn't regard the RF 600 and 800mm f/11 as any sort of RF mount successor to the EF 400mm F/4.0 DO L...

    Behind of 'keeping Canon happy' and economic thinking: The EF mount is appropriate for 3rd party lenses when the AF is important. That...

    good point on film! and thank you.
  • justaCanonuser
    Thank you Richard, for this very interesting analysis and conclusion. I am with you, I think when Canon went mirrorless, it was logical...

    I'm not saying it's happening now but im not excluding it to happen in the future as AI image generation gets better and better.

    Once again, the RF 100-400 is not a replacement for the EF 100-400. Only the focal length is the same, nothing else. It's in fact a...

    Okay, so I've been thinking about what this array might look like. One thought is: Reading that as an array of 3x3 pixels would be...

    You're not the one who's confused. I had a similar exchange with @GMCPhotographics, where I posted a graphic making the same point as...

    Not in the budget range, but compare the EF 11-24/4 to the RF 10-20/4. You’re apparently confusing the RF 100-400 with the RF 100-500L...
  • Richard-CN
    I'm confused by this. usually what happens is that the image is straightened which by nature of the process would push the corners...

    No, it doesn’t do anything to the RAW file. Do you not understand the point of a RAW file? The RAW file is uncorrected. You can choose...

    I asked honestly, how many entry-level cameras does Canon need ? I didn't suggest that they should have more or less. And I didn't...
  • Richard-CN
    with 100-400 - that's just engineering, there's no digital correction happening there or shouldn't be. The projection of the image...

    Sounds like you skipped half of Richard’s piece. Also, there can never be AI generated corners in a camera, as there’s people shooting...

    With IS as well.

    I have no idea where these suggestions that the digitally corrected corners are filled with AI-generated image data come from, but I...

    Direct comparison with the EF era is tricky because the overall size of the market has shrunk so much. The economics of the thing must...

    The current EF 100-400mm ii L costs new here £2599 and the RF £749. The original EF 100-400mm was discontinued in 2014 and was well...

    I make this point frequently in these discussions, but I guess some people’s views on the matter are too distorted to accept that fact...

    If this isn't totally made up, they could be using something more complex than the quad-bayer array like smartphones normally use for...

    Lens corrections are great! It's a transparent tool that just makes lenses lighter and less distorted, but: "Less expensive" is the...

    If people don't want digital corrections they should just use film cameras ( ͡° ͜ʖ ͡°)
