  • Mike Davis and followers seem to be lost in physics, so I'd like to clarify a bit. Diffraction reduces contrast up to a certain spatial frequency and looses information beyond. With current...

  • The sharpest aperture depends on focal range and image position. C/B/E = Center/Border/Extreme: 24mm C/B/E: F4.0 / F8.0 / F5.6 40mm C/B/E: F5.6 / F4.0 / F8.0 70mm C/B/E: F5.6 / F8.0 / F8.0 [source: ...
  • While we're at it, I'd like the "Standard" setting for the central button to mean "Eye AF" if focus mode isn't in flexible spot. As it is now, it is a bug: It's either "Standard" (required in ...

  • This is what *research* at most-famous US lab MIT looks like? Toy projects which would be classified "product development" in any small engineering company in any developed country?

  • I'll try ;) Focus and recompose simply is no option with AF.C, or if you do a series of a subject. The recompose error isn't such a big deal with a compact camera, although at 24mm F4.9 equiv. it ...
  • works. However, in order to keep Eye-AF, one has to allocate it to the C button, right? Or is there another way to keep the Eye-AF feature? IMHO, "Standard" really should continue to do Eye-AF when ...
  • Replied in Almost
    Pretty GF :) As for your question, almost: The RX100m3 would be appropriate for portrait at the tele end which translates (in terms of your D550 APS-C camera) to 47mm F5. A few of the portrait ...
  • Of course, my D810 and RX100m3 are just placeholders for one no-compromise plus one good-and-compact-enough combo. My point was I personally don't believe both can be made in one camera (already ...
  • > If I asked you to set the aperture to "F/4 equivalent", what would you do?

    This isn't a hypothetical question. In a photo workshop or professional production, you WILL be asked so. And a M43...

  • @mostlyboringphotog: The reason why I personally like the concept of equivalent parameters so much is this: If you characterize a photo, you normally have to say which FL, F-Stop, SS, Iso, format,...

  • @pidera, I recognize your early contribution. However, this post did not yet introduce the term "equivalence" which covers all aspects of IQ, including noise and diffraction effects, not just FoV...

  • The above is an oversimplification, of course, but makes my point: The D810 probably is the best money can buy in its class of weight and size. No mirrorless comes close, A7r included. And 645Z is ...
  • @panos_m: Thanks for the link, it is 13 days older than my Fredmiranda link. So therefore, this may indeed mark the first occurence of the concept in the internet.

    @JA Canon shooter: I try to...

  • The theoreme isn't about the math involved. The equivalence theoreme states that two images taken with two (ideal) cameras using different sized frames can be completely indistinguishable even when...
