  • It is true, Sony lenses do seem to carry a slightly unreasonable price premium. I'm honestly not sure why that is. The quality is usually good...but not always excellent. It would be nice to see...

  • I really appreciate this guys enthusiasm, candor, and appreciation of Sony's position in the ILC market. He knows where he is, he knows the battles he has to fight, and he knows he has to keep his...

  • T3 nailed it. Sony cameras can use just about any glass you want with adapters. If you prefer Canon glass, then adapt Canon glass. I'm a Canon user myself who's adding Sony to his kit. Having owned...

  • Someone needs to clarify the "(AF not possible)" bit with regards to the TC-1.4E. I highly doubt that is a typo, as it takes explicit intent to put such a statement in parenthesis. Does it refer...

  • Commented on Wilderness Sunset in the Wilderness challenge

    First off, beautiful photo. I love the color contrast.

    That said.... Leica M9? I'm quite surprised by the amount of noise in the foreground. I suspect there was a decent shadow push...there is...

  • "**Compatible with TC-14E series teleconverters (AF not possible). Compatible with TC-17E and TC-20E series teleconverters. AF is only available when used with DSLR cameras that offer f/8 support....

  • I would say that abortabort nailed it. It's less about improving your photography, and more about expanding the range of things you have the opportunity to photograph. I get a lot of that when I...

  • Heh, I hit 80k actuations on my 7D in a little over a year. :P I'm at 50k actuations on my 5D III, less than a year. I don't think the actuation count bar would work for me. ;)

    Sony stuff has me...

  • 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:

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

    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:

    http://jonrista.com/2015/03/01/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...
