Pentax K100D better than istD?

Discussion in 'Pentax' started by martinbarry55, Jan 27, 2007.

  1. I hear the sensor of the K100D and similar new Pentax digital SLRs
    puts out sharper .JPGs than the istD did. I have an istD and found
    that this was one my most important issues with it. Can anyone verify
    that the K100D performs better in this respect?

  2. I hear the sensor of the K100D and similar new Pentax digital SLRs
    It's the same sensor, as far as I know, but the claim is that the
    firmware does apply more sharpening. Also, the SR would have the effect
    of actually making a good number of shots sharper than they would have
    been on the D. So all in all you'd probably perceive there to be an
    improvement in this regard. On the other hand, if you still have your
    D, it could be a better investment to spend a little money on a program
    that can painlessly batch sharpen your JPEG's. Might even be freeware
    that could do this well enough.

    Another option: Shoot RAW and batch convert to JPEG.

  4. Then if the firmware is applying sharpening automatically, is it
    possible .JPGs coming out of a K100D are noisier as a result? For
    instance at ISO 1600 or 3200 it might be very noticeable.

  5. Then if the firmware is applying sharpening automatically, is it
    *All* firmware applies sharpening when creating a JPG - it's practically
    a necessary part of the conversion. The only question is what kind of
    algorithm is used, and what parameters are supplied. And it is true
    that more sharpening might result in noise being more prominent as well
    (if not literally more of it), all else being equal - that is, if you
    took the exact same algorithms and simply cranked up the amount of
    sharpening. But if one algorithm has an inherently better sharpening
    algorithm than another, it seems entirely possible that it might have
    better noise handling algorithms too.

    Which is to say, I don't really know for sure, but in general, the K100D
    is not generally perceived to be an especially noisy camera for its
    sensor.
