  • Like proving water is wet.  ;-)
  • Replied in Can do!
    With regards to [technical] photography, exposure is the density of light projected on the sensor during the time the shutter is open (units: lux · seconds or, equivalently*, [visible] photons / ...
  • Nikon's new mirrorless FF have IBIS, too, as do Pentax's latest DLSRs.  Aside from IBIS, there are ILIS lenses for systems without IBIS although, of course, not all lenses have ILIS.
  • Bob's idea of shifting the sensor is an excellent one *providing* that the image circle from the lens is large enough and the IQ of the projected image outside the 21.6mm diagonal suffer only ...
  • Have to give a major thumbs up to these photos -- very nicely done! Now, here's the big question: how many times did the photographer get kicked in the face? : )

  • Replied in I concur.
    If Olympus used an APS-C sensor on a mount that was compatible with current mFT lenses, that would be a great move!
  • Replied in Not really, Don.
    If by "creamy", you mean "less noisy", a FF photo of a given scene from the same position with the same focal length as a photo from a smaller format, where the FF photo is cropped to the same ...
  • An APS-C sensor probably costs nearly the same an an mFT sensor and allows for quite a few lossless aspect ratios to be used, and, for those aspect ratios that are not lossless, significantly less ...
  • ...that is the question.  Opting for the latter, there's the Olympus White Paper that Bob linked: (1) Size of the 4/3-type Sensor The standard diagonal length of the sensor is 21.63 mm. It is half ...
  • In fact, the 6D was well received and even highly praised. The 6D2 was derided on the basis of no DR improvement over the 6D (in contrast to the 5D4 which had a significant DR improvement over the ...
  • Ready when you are: (1) Explain how what PDR tells us about the visual properties of the photo, preferably accompanied with examples demonstrating this difference.
  • Thanks for the updated link!
  • Kind of you to say!  I've also taken a lot of horrible photos.  Would you like to see some examples?  ;-)
  • Primes are more limiting than zooms in that respect. With a prime, you choose your perspective or framing. With a zoom, you can choose both. You can shoot any exposure time you like with any lens ...
  • ...there's no reason to use a prime on mFT other than size. The speed difference between zooms and primes certainly isn't 3-4 stops and the resolution difference is inconsequential. This is ...
  • Exposure is the density of the light projected on the sensor, whereas total light is the total amount of light projected on the sensor.  Thus, for the same exposure, 4x as much light falls on a FF ...
  • I can't talk about the Nikon shooters you know, but here's what a full size 70-200 / 2.8 looks like on FF wide open: No doubt the IQ is a lot better still with more modern 70-200 / 2.8 lenses on ...
  • I get it now -- thanks, and sorry for the misrepresentation! Will do! The notion of light is *central* to Equivalence. I 100% agree. I'll start a thread on it in Open Talk or the PST forums and ...
  • All fair to say.  However, do you disagree that the "creaminess" that NCV is talking about that sometimes results in FF delivering "more pleasing results" doesn't come from the instances when FF ...
  • So, when gardnersassistant said : I think that is a bit harsh. I use four different formats, 1/2.3", m43, APS-C and FF. Over time I have tackled similar subjects with all of them. It has been ...
