What are the characteristics of digital camera lens compared with traditional lens?

The electronic photosensitive element is optimized, that is, the color temperature and tone are different, and the glare is controlled. In short, it is much worse.

Of course, there are more than these, and there are some obvious changes. For example, some digital camera lenses don't have Jing Shenbiao, and the aperture ring is cancelled. These functions are unified on the body. Nikon G-prefix lens has no aperture ring, so it is very troublesome to put it on traditional cameras. Moreover, many digital SLR lenses are designed for medium format cameras and cannot be directly installed on the traditional 135 camera (equivalent to full-frame digital SLR), otherwise there will be black circles in the shot. The traditional 135 lens can be modified to a digital SLR as long as the bayonet is matched, but some of them will lose the functions such as autofocus.
