  • My advice is like all the others'.  Shoot RAW and convert later.  No disadvantages at all and lots of advantages in terms of post processing.
  • I agree. Perhaps a touch of constipation or diarrhoea is involved... ;) They publish noise and DR results for cameras and test lenses for sharpness, vignetting, distortion, flare resistance and ...
  • Mine is reading about other photographers' weird habits... ;)
  • How can you have a discussion about or compare lens focal lengths at various distances without first knowing the actual focal length of a lens at infinity first? Any testing or discussion about ...
  • Not an attack but an observation.  And if you can't work what I meant, by what I wrote, then you have no business criticising my observation about you. Really?  My concern for the lack of reporting ...
  • Replied in No
    Perhaps for the strict meaning of the word, but explaining why an image is larger on one sensor and smaller on another despite being the same nominal focal length. In this context it is especially ...
  • First of all, whether a camera is mirrorless or a DSLR, all other things being equal, there will be no difference in IQ. All the cameras you mention are good but check out the IQ differences using ...
  • Yes it does.  It sometimes goes by the name of "crop factor" or "reach", but the size of the sensor will determine total magnification. Focal length and aperture don't change, but the smaller the ...
  • I think you posted this in the wrong forum - try Leica Talk... :)
  • Not obsessing at all.  And how do you know the "problem" doesn't exist? - blind faith?  If I was being "paranoid" why would I want to know what the actual focal lengths and apertures of lenses are? ...
  • Dr Jon

    The thing is that they did do a test on the Pentax and later on the Hasselblad even though their policy was supposedly not to. They decided to publish one but not the other. When they...

  • You don't know me and you have no right (or enough knowledge) to "psychoanalyse" what I write. There seems to me little point thoroughly checking and testing everything about a camera and lens ...
  • There is always something to report.  If the lens is accurately described in terms of focal length and aperture it's worth knowing - just as it's worth knowing if it's out of spec. Find some that ...
  • Hopefully they don't drop any...

  • Thanks for that.  Certainly the tested figures are so close to the description that they qualify as accurate.  Indeed, even if they varied by a number of percentage points from the description they ...
  • Where? That's true for almost everyone.  However, what about 180 or 220mm?  what about just one millimetre at the wide end of the range? Angle of view still matters. Perhaps it's not meant to be ...
  • Let's see if I have this right...

    DxO test a Pentax 645Z and do an "in-depth analysis" of a camera they were never going to publish because they don't publish "medium format" camera tests even...

  • We can at least start somewhere.  At the moment we have nothing on the accuracy of focal lengths or apertures for any lenses. If you have any current or recent sources, that would be great, and ...
  • But that's exactly my point!  If actual focal length and aperture isn't tested or reported, I don't have any examples of lenses "out of spec", but by the same token I can't cite even one lens within ...
