  • Canon is not about to go belly up, not from competitive forces anyway. The whole digital photography industry seems to be going through a transition, however. The P&S market has basically been...

  • The self-canceling is achieved by using a different second LPF layer in the filter stack over the sensor. It cannot be turned on and off, it is something that has to be chanced in manufacturing....

  • @En Trance: I'm not sure where your hostility is coming from. I find it interesting that discussions about DR seem to evoke that...

    Anyway, your hostility aside. Assuming for the moment that the...

  • I would offer that it is more than just the gap, however. That is certainly a big factor, but there is also the characteristic of the read noise. With an Exmor, or say the NX1 sensor, the...

  • @Eleson: The dynamic range of a real-world scene can be small, or it can be immense. If it is immense, say 18-20 stops, then yes, there would be a 'gap' between the dynamic range of the camera, and...

  • Well, now that we are into the realm of demanding people accept something, and out of the realm of a reasoned technical discussion, I'm out. I have no interest in where this discussion is going, as...

  • For those who may be interested, I compared an A7r to a 5D III a short while back. You can read the article here:

    I have original RAW files...

  • For reference, I wrote a comparison article, using the A7r and 5D III, that demonstrates the value of having more dynamic range:

    There are no...

  • I actually have a side-by-side comparison of this, 5D III vs. A7r. You can see it here:

    http://jonrista.com/2015/03/01/dynamic-range/

    I purposely exposed both cameras to very lightly clip the...

  • En Trance, I don't think you quite understand the value of dynamic range. Dynamic range is not some fixed 'trait' of an image...it is the space within which the data that makes up the image fits....

  • I don't see how time of day is a problem. Sunset (or sunrise) is the time when most landscape photographers get their most dramatic shots with brilliantly colored skies. Just scan through the most...

  • I am a bit dismayed by the fact that there is still visible banding. It's lower than previous cameras, but it's a bummer it exists at all. There is also still clearly some color blotch in the soil...

  • @En Tran: When I say "highlights", I don't actually mean the sun. I mean the sky around the sun.

    The sun is probably a multitude of stops brighter than the sky, so there isn't much point in...

  • While the 5Ds doesn't bring a huge multi-stop improvement in DR to the Canon lineup, one thing I do recognize is the color noise seems to have dropped. Banding is still there, sadly, however I...

  • You could never have too much DR. Dynamic range is simply the ratio between the clipping point and the read noise floor. Lower read noise means lower noise overall. With more DR, you simply have...

  • It is not underexposed...it is exposed for the highlights. Exposure with a digital sensor is not as fixed a concept as it was with film. With a digital sensor, to make the best use of a sensor's...
