To form an image the lens makes the Fourier transform of the light wavevector spectrum, so it must be the same if are going to make an absolute comparison of different systems.I speak in terms of...

I well understand your wish to bind the 2 and 3 pixels for EM5 and D600 respectively. But this approach is not good and does not bring something new on the signal/noise properties.  What I was...

We are speaking on a signal/noise ration in an image, aren't we? The image is not created by a single, two or even by three pixels. This is trivial, isn't it? To form an image we need what is...

You are correct only with respect to the angle of view and the depth of field. The rest is false. The area of 35mm sensor is approximately 4 times larger than one of m43. It means that at an equal...

Focal length and f-number are explicitly the properties of the lens. They do not depend on a camera format or sensor size.The aperture is always defined as the ratio of the focal length to...

Below is a photo of my quick sheet, where I show how my formula is derived. Hope, it can be useful for you. In my formula, as you can see, the size of the circle of confusion is defined by diameter...

Yes. Fine, I agree. Also, I think the factor 2 comes from agreement on a size of circle of confusion. To simplify eqns, I prefer its defition in terms of a full viewing angle rather than half-angle.

For estimations this simple formula can be used for arbitrary sensor size: dD=(D/F)^2*FN*CC/CF dD - depth of field;D - distance to the subject;F- lens focal distance FN - F-Number;CF - sensor crop...

"Low" is just misspelling of "Law". I am sorry for this mistake.My physical language in this particular case is based on principles of Fourier spectroscopy. This extremely well developed subject,...

In your math I do not see the physical law to start with that defines the SIZE we speak on. If you start from a physical law then I can check your correctness.To get my formula the principle...

A diameter of Airy disk depends actually on criteria used. From indefiniteness principle one can find the following formula for the spot size limiting the resolution:SIZE=F-STOP*WAVELENGTHFor...

Yes, " ...the laws of physics imply that the momentum is always preserved ..." Namely because of this , when the shutter blades stop the rest of the body stops too.

Yes, it seems as we are almost coherent in that what provides the "shock" effect. Of course, you are right - when the blades move down, the rest of the  body will move upwards, while  the...

What was discussed above is OK not only for the free space. If the acceleration of a camera during the blades motion is significantly higher than G (and this was just discussed in LumoLabs...

If the center of mass of the blades is stopped then the center of mass of the rest of the camera is stopped too. This is the condition for the center of mass of the whole system to be not changed...

That is very simple. The body moves until the shutter blades stop (immediately as the blades stopped the body stops too; only the wave package generated by the blades can play the game after this)....

Thanks for the references.About your experiment.If I understand correctly, when you have placed the camera onto the concrete floor the blur has disappeared. If so, then it demonstrates that...

Anders,I have read your posts and impressed by your attempts to find the TRUTH. Unfortunately, this kind of problems is very complicate (there are too many parameters that can change the whole...
