  • I love pictures like this, so don't get me wrong, but... Why shoot it at ISO 560, f16? Isn't the reason for shooting this to capture the immense detail? I suppose if this was shot handheld outdoors ...
  • Thanks for the math. You are absolutely correct and I was using area when I should have been using a linear measure. We agree on ALL points.
  • Yes.
  • I guess if you define words differently than everyone else in the world, you can't possibly be wrong. Of course, it makes communication really difficult.
  • So you think that a print from a 50mm lens set at f4 on an 8x10 view camera focused at the same place as the same lens on a FF camera will produce equal DoF? Uh....OK.... We have nothing left to ...
  • It exists. TrueDof-Pro.
  • Diffraction and DoF are completely unrelated.
  • Replied in Sorry
    This is wrong. If you'd ever shot large format film, it would be obvious.
  • Don't confuse two things here. One: Size of the sensor relative to the enlargement. This is the most relevant. Two: Resolution (pixel density). This only impacts the smallest blur circle capable of ...
  • Mike, I think you are being closed minded. Imaging has changed from film to digital sensors. DoF has changed (slightly) as well. Emphasis on "slightly".
  • Mike, I think you are limiting you definition of CoC to the printed size of a blur circle. But CoC happens at two times. First, the size of the blur circle in the image projected onto the sensor. ...
  • For example, a 14mm lens shot at f5.6 and focused at about 4.5 meters will record everything from about 2.5 meters to infinity with no blur spot larger than 10 microns. This will not be ...
  • Viewing at 800% on your screen has nothing to do with DoF. I hate to tell you, but resolution (well pixel pitch anyway) does in fact have something to do with DoF. That is what I am proposing here. ...
  • Mike, I am not talking about some low resolution sensor. I am talking about a 36mp FF sensor. I regularly shoot landscapes with the entire image having no CoC large enough to be recorded by the sensor.
  • YES! Thank you for verifying that I am not crazy. Sometimes I wonder.
  • What? If DoF in part is determined by CoC size on the sensor, then it follows that if an image is enlarged enough, the printed blur circles (no matter how small) would become visible (manifest as ...
  • Pick up a book on contemporary photography. There are many many unexplored areas in photography.
  • Most of what is being written here is correct. DoF is not real or measurable without knowing the observer's viewing distance, visual acuity, and print size in addition to the focal length, ...
  • The problem is that with a non-bayer, Fuji specific color array (x-trans) the choice of software used to process the files is critical. I shoot landscapes and have overcome this problem by shooting ...
  • I'd love to sell one or the other but love them both so much for different reasons, that I can't. The problem with getting into another system without selling the other is the huge expense of ...
