Thinking about buying the GFX? Article by DpReview

Arthur, if there is ONE thing in photography that is a useless metric, it is magnification on the sensor. No-one will ever care how many millimetres of a subject are on a sensor. They care about the resulting image, how big something is on the image. When you use a 1:1 lens, MFT will show twice the magnification in macro photography on the print on the wall than FF does. And these "MF" cameras show even less magnification on the print on the wall.

 

"He doesn't bother to point out that more will fit on the larger frame for a given magnification!"

Good thing he did not, it would be the silliest thing to point out. 

 

About that f-number. No one with any idea about what they are doing shoots with a certain f-number as goal on different formats. Simply because that f-number will give differently sized apertures, resulting in different DOF. A photographer only has two tools to shape the look of an image, FOV and DOF. For FOV he can change focal length, for DOF he can change aperture or the f-number. 

So, to get a certain image, one shoots with equivalent focal length and f-number.

 

Strange arguments against that article, to be frank. 

 

I always argue/advice that one does not need to go from APS-C to FF unless one needs the ability for less DOF than APS-C can provide with the lenses it has available. With the current lens line up for the Fuji, Pentax and Hasselblad MF trio the same is not true. They do not offer lenses which allow the possibility of more shallow DOF.

 

What remains:

  1. better dynamic range than the Canon 50mp FF sensor
  2. more light capture possible with equivalent focal length and f-number if exposure time does not have to be the same
  3. the possibility that 1 or more lenses render so attractively that they alone make a case for buying the camera, for some photographers
on the downside:

  1. no AA-filter available, so aliasing fake sharpness and false detail
  2. because the Fuji and Hasselblad are mirrorless and rely on the (big) sensor constantly, noise from heat will be higher and other heat issues might become apparent in use cases
