Does sensor size impact the diffraction limit of a lens?

Does sensor size impact the diffraction limit of a lens? No. Therefore, if the sensor is larger, and the photo-sites for the same resolution can also be larger, does this influence the diffraction ...

Do very short shutter speeds result in diffraction?

I know this is an old question, but just wanted to contribute a photo that exhibits a shutter-induced diffraction effect. My Nikon 1 V2 camera has both a mechanical shutter and an electronic one. When ...

What is the difference between Diffraction Spikes and Lens Flare?

Diffraction spikes are caused by diffraction at the edge of the aperture. The number of spikes relates to the number of blades and the intensity of the effect relates to the exact shape of the blades ...

Is it better to shoot at diffraction limited aperture or sharpest lens aperture?

"its known that lenses are generally sharpest at the F/8" That is not correct. Some lenses are sharpest at f/8, most reach their max at one to two stops from wide open, and some are sharpest when ...

Can the diffraction limit be overcome with superresolution?

Can the diffraction limit be overcome with superresolution techniques? Sort of, to a limited degree. Using sub-pixel shifting of the imaging sensor, in effect you are increasing each pixel size while ...

What kind of lenses with a "slightly different diffraction behaviour" were used in "large format photography in the 1980s"?

Apodizations filters in large format lenses were very popular in the 1980s. The baffles in such lenses can significantly affect the diffraction characteristics of such lenses. Although lenses such as ...

Is this just chromatic aberration? Or is something else happening in these photos?

The primary reason both images look blurry is because in both of them the point of sharpest focus is closer than most of the scene. Shooting with a wide open aperture minimizes depth of field, so ...

Airy disks and pixel pitch on circle of confusions?

Pixel pitch does not determine the standard CoC limit, and it is not a factor considered in the DoF calculations. That's because the accepted CoC limit for normal viewing by an average individual is ...

Does sensor size impact the diffraction limit of a lens?

No. Diffraction depends on the aperture and pixel size. The sensor size itself has no influence in the equation. A larger sensor as you say can have larger pixels but it can also have smaller ones. It ...

Does sensor size impact the diffraction limit of a lens?

The diffraction limit is the resolution where the Airy disks significantly overlap, completely independent of whatever they're falling on. But if that diffraction limit is at a higher resolution than ...

What is the Nikon D3200's diffraction limit?

It's a little more complex than the question seems to indicate. Intended display size also comes into play. This is because the Diffraction Limited Aperture (DLA) of a sensor is only the beginning of ...

Is diffraction limited aperture independent of lens?

You're confusing diffraction limited aperture (DLA), which is where the effects of diffraction are first barely detectable using a specific digital sensor, with the diffraction cutoff frequency, which ...

Can the diffraction limit be overcome with superresolution?

All camera optics are plagued by twin demons of interference and diffraction. These yield stray light rays that comingle with the image forming rays. Diffraction is caused when light rays from the ...

Is it better to shoot at diffraction limited aperture or sharpest lens aperture?

As is usually the case, it depends on your scenario. The "best" aperture, which I will interpret as being the aperture at which the lens produces its maximum resolution results, will not necessarily ...
