    Can do: http://www.cambridgeincolour.com/tutorials/diffraction-photography.htm Diffraction is an optical effect which limits the total resolution of your photography — no matter how many megapixels ...
  • The 1.5x crop factor will result in the 200-500 lens on DX having the same framing as a 300-750 lens on FX.  However, the focal length of the lens is still 200mm - 500mm.
  • Given the choice of being as dumb as Bob or as smart as you, I'll go with the former.  But that's because I'm as dumb as Bob -- maybe even dumber.  ;-)
  • So this thread that you started: https://www.dpreview.com/forums/post/59354172 was totally different, right?
  • ...freakin' hilarious!  :-D :-D :-D

    Thing is, most people couldn't pick out the photos taken with APS-C vs FF or a 70-200 / 2.8L IS II and a 70-200 / 4L IS, or care about whatever differences they might see, either, yet ...
  • Why are you actively trying to distort the simple situation I described in my entry into this thread? I mean, seriously -- what is that about? Let me quote it for you, as it will show that I was ...
  • Let me quote my entry into this thread for for you, as it will show that I was more than a little clear about the situation I was discussing: [It is not possible to crop without losing IQ]. I ...
  • Then the photos are not of the same scene.
  • Makes no difference since the implicit assumption is a static scene with constant illumination. That two resulting photos are photos of different scenes. No -- less of a scene is not the same ...

    The thing is, however, that the 5D4 sensor is pretty decent.  The 6D sensor was marginally better than the 5D3 sensor, so everyone expected the 6D2 sensor to be marginally better than the 5D4 ...
  • I mean two photos of the same scene. A crop of a photo is not the same scene as the original photo. I am confusing nothing. I am talking about photos of the same scene -- note the text I ...
  • Show me any two photos *of the same scene* where the photo made with less light is less noisy.
  • Replied in Trick
    I don't disagree.  Still, I have to wonder if those who purchase the 6D2 for $2000 wouldn't feel a bit "cheated" if Canon released a 6D2+ in November for $2400 with 5D3 AF, a 20-24 MP version of ...

    I'm kind of keen on taking a step up in sensor performance, not a step back (albeit a small step back).  I chose the 6D over the 5D3 because of this smaller differential in sensor performance and ...
  • ...your nonsense in the PST forum with the *exact same BS* you're doing now: https://www.dpreview.com/forums/post/59509996 To me that shows clearly you were out to cause trouble. The thread was ...
  • No, same total amount of light.  If it was the same amount of light per area (same exposure), then the larger sensor would have a noise/DR advantage, all else equal. Even for the same pixel count, ...
  • Replied in You can't.
    Not possible. I assume we are talking about taking a photo at a wider focal length and cropping to the same framing as a longer focal length on the same camera using the same relative aperture and ...

    Fair to say. However, I'm also looking for an improvement at higher ISOs. Nothing dramatic -- a half stop at ISO 6400 would be the most I'd ask for. I'm pretty sure they know what's more profitable ...
  • Replied in Can
    I surely hope that things pan out that way and that the sensor is at least as good as the 5D4 sensor with regards to DR and noise throughout the ISO range -- that would be enough for me to go ...
