It is understood that ALON is a transparent aluminum material, and unlike our common aluminum cans, it looks as transparent as glass. ALON has a Mohs hardness of 9, which is 4 times that of quartz glass and 85% of sapphire. It can be used to make bulletproof glass and explosion-proof windows. When used to make lenses, scratch resistance can be improved.

In terms of light transmittance, ALON has a refractive index of 1.79, which is 1.4 - 1.5 higher than that of ordinary glass. Due to the high light transmittance, the lenses can be thinner and the lens design can be made lighter. In addition to the above features, ALON lenses are not affected by color aberration or ghosting issues.

However, due to the complicated manufacturing process of ALON lenses, it will only be used to replace the front lens and high-refractive lens, otherwise the cost will increase significantly.

Now, the biggest doubt for netizens is whether the lens is manually or autofocus. If it is autofocus, plus the characteristics of ALON, it will be very attractive.
