Is there any difference between focal plane and general lens?

Nowadays, in order to save money, online movies all use EF bayonet lenses, and some large film manufacturers have begun to sell EF bayonet lenses to adapt to the market, but there is only one kind of aperture for image quality. However, in real digital cinema machines, all the ones without EF bayonet are PL bayonet. Focal plane manufacturers provide a variety of image quality options on this bayonet, such as Zeiss CP series UP series MP series. General low-cost digital movies also need to be turned on.

2, the picture quality is different.

The resolution of focal plane is not the same as that of general lens, and the worst title is much better than that of general lens. The focal plane can restore the details of things very well, with transparent colors and even and natural color transition. The contours of things are obviously contrasted. Follow the focus.

3. Different treatment methods.
