These are photos which use 8 bits of data for each of the red, green and blue colour channels. This is enough to give over 16 million colours – more than enough for photographic images. The JPEG photos taken by digital cameras are 8-bit images.
8K video has a horizontal resolution of around 8,000 pixels and is still in its infancy, though Canon, Sony and Nikon now all make 8K Mirrorless Cameras.

Because these cameras have a mirror in the body, even though it’s a non-moving one, the rear of the lens is further from the sensor, so Alpha mount lenses are physically different to Sony’s E-mount lens range.

These are optical flaws produced by camera lenses and which are largely unavoidable except in the most expensive or the simplest lens designs. They include distortion, chromatic aberration (colour fringing), vignetting (corner shading) and edge softness.
