  • Oh and good point about 14-bits, a 750 runs about 5 electrons per ADC step at ISO 200 which is getting tight if you boost a 1200 electron range (light level at ISO 6400) since you can only see...

  • i really wasn't making any comparisons to the Canons, just commenting on what I saw just on invariance. My (sole!) point being actually shooting a Nikon at ISO 6400 would seem to be a better idea...

  • The point I was exploring was that the Nikons do seem to have quite a bit more read noise at lower ISOs, so lowering the ISO and underexposing will add significant noise to the non-highlights.
    The...

  • Yes, although that does start to look less natural after a while so is both an art and a skill - well hopefully anyway ;-)

    At low ISO it really does need a suitable subject to use 14 DXO stops, I...

  • Note I'm just debating this out of interest, not arguing at all as I think ISO invariance is a good thing. However the D750 read noise comes out (per sensorgen) at 4.7 at 200, 4.3 at 400 and 3.4 at...

  • I get that, though it's a pain reviewing the images and you don't have anything to show that much DR on. Plus you can play that game a little bit with the 7DmkII provided you start a bit up the ISO...

  • As an aside Canon's sensors are as good as anybody's, their issue is they digitise the signals off-sensor which limits the DR you can get at low ISO due to adding some noise. (For example the 6D...

  • It's moire not aberration, down to the lack of an AA filter or a weak AA filter. There's not much you can do about with a Bayer sensor as you only get info on one colour at each pixel so you have...

  • It is one of dprs main attractions... (Sorry guys.)

  • It's an old camera and a specific video camera, it's natural the price should drop (it was announced in April 2012). Anyone expecting camera body prices to hold up over time really hasn't been...

  • Samuel - I just bought a 16-35 f4 and it's very sharp away from the extreme corners, but I think the 10-22 (which I traded in, not shooting APS any more) is actually relatively better in the...

  • But are you aware of any camera that will give 10 stops of DR at ISO 6400, let alone above, so even if you can shoot above that the DR is falling all the time.

  • I would assume that at ISO 800 and up it will have better DR than a D5500 based on DXO's results for similar cameras. Low ISO DR is REALLY handy if you need 3+ stop shadow pulls, but few people do,...
