Camera lens material problem
Resin is light, low cost, but the optical performance is not good, such as light transmittance, color difference, what difference is worse than the optical glass, but the problem is not used in the card machine, because the card itself is not good imaging, no need to use expensive The glass lens. Of course, the stress is generally glass. There is nothing in the camera parameters that relates to the lens material.
Are generally made of glass
Resin is worse than glass
Camera parameters and lens material has nothing to do, but the lens glass is good or bad affect the image of this lens color dispersion, purple edge of these reasons
At present, Canon's use of fluorite lenses and Nikon Sony's ultra-low dispersion lenses are used for better house lens dispersion and color.
Weight and this related. Resin afraid of the fire, the glass is better. Glass wearably. Resin lighter. But now the general dc is made of resin.
