Is the resolution limited by diffraction in theory ? Diffraction can be reversed by deconvolution, so in pure theory, does this limitation exist ?

I have read that noise can be a problem, in this case let's consider that you can shoot with very good exposure at low ISO.

Let's consider that you have a perfect lens and that you have a high resolution sensor (I mean the sensor is not the limit).

Is there a limitation and if so which one ?



Google "super-resolution imaging" and you will find lots of information.


Maybe a bit too much. Super resolution is an overused term. "Breaking the diffraction limit" is another one and they are often used together.

One of the uses is in microscopy or should I say nanoscopy, where one uses evanescent waves for imaging.
