Mirrorless cameras, as the name suggests, lack the mirror mechanism found in DSLRs. This design allows them to be smaller, lighter, and often quieter than their DSLR counterparts. Mirrorless cameras use an electronic viewfinder (EVF) or simply the digital screen on the back to display the image directly from the sensor. This setup enables real-time preview of exposure, white balance, and depth of field.

Alien Photonics precision aspherical lenses are made using CNC glass polishing technology. Once design is confirmed, the blank glass material is polished using computer numerical control (CNC) glass polishing machines. After that (optionally) anti-reflective thin film coating is applied to reduce unwanted reflections. Next step is final testing and inspection, after that – aspherical lenses are stocked or shipped to Alien Photonics customers.
