    Yes, evidently. The concepts you are fixated on are applicable to pixels, not to pictures. Image noise is inversely proportional to...

    I wasn't exactly intending to enumerate all the causes of the likely years-long implosion of consumer electronics. I agree with the...

    Regarding Meike, I bought one of their EF-to-RF 0.7x Speed Boosters about a month ago. It was $250 gamble, optically about as good as...

    I'd love to see Canon run with Sigma's 500mm f/5.6 concept at the same tier as the 200-800 silver ring, making it a series of mid-tier...

    This is really interesting, didn’t know this! I’m still using the original R and really starting to see it lag behind newer cameras...

    Canon has a patent application for a 400-600mm f2.8-f4 lens (and a Canon RF 300-600mm F2.8-4.5L) See...

    Exactly my point. "We do not comment publicly on that," is a frequent answer from Canon to many questions. Hypothetically, Canon tells...

    Canon execs are well practiced in giving vague non-answers, so there is no reason for them to flat out lie.

    I definetly don't understand your discussion. In some cases you seem to agree but in the end you disagree. That is confusing. I think...

    That is not an easy question to answer. Behemoth is an evocative word term for something of monstrous size, power, or appearance. It is...

    I am sorry but this new article adds objectively nothing to the previous discussion. So if the aim was to convince people that Canon is...

    Excellent shots!

    Probably a shell company set up specifically to sell RF versions of the Meike lenses under a different brand. That way when Canon...

    I wonder how many more times you will need to explain that? :ROFLMAO:
  • roby17269
    I haven't heard of a Canon RF 400-600 2.8-4 - that would be awesome if indeed they make one but I would expect it to be more than...
  • neuroanatomist
    No, we don't agree on that. For an individual pixel, smaller means more noise, sure. People who measurebate pixels love discussing that...
  • roby17269
    Do you have any links about the Sigma 300-600 4 being not good at 600mm? The reviews I have seen speak highly of that lens. Also you...

    Very nice shots, antonn. I really like the second one.

    More choice is always better, you mentioned two options not available with a Canon body. You are comparing a prime 300mm with an equally...
