In Perspective, Planet: Crop or Crap

Hi, Fahim,

Thank you to that link to a very interesting and worthwhile essay.

Zack echos my point that, in digital cameras, we somehow decided that a format size of 36 mm × 24 mm is the ne plus ultra, the whole enchilada of sensor sizes, and we must think that anything smaller is an unfortunate, sad compromise. What about sensors larger than the ne plus ultra? Well, they are wonderful, but too big, and too expensive.

Of course in the matter of sensor sizes, as with many other things, there is a spectrum over which various properties vary (sometimes predictably, sometimes not). I mostly shoot today with a camera with a 3/3 ("one inch") sensor. And with that I enjoy, even at a large aperture, a great depth of field.

One's mileage may vary.

Best regards,

I could only get half way. He made his point within the first 30 seconds!

It is a beautiful video. A little secret: movies don't depend so much as on detail intensity as on shapes and great sound.

Sensor or film size just depends on end use, habit and convenience. But in truth, wedding albums can be of Pro quality using 4/3 sizes sensors.

Obviously, larger sensors provide more leeway.
