Ultra-Wide and Fast: Laowa 10mm f/2 Zero-D MFT is an ultra-wide and ultra-fast prime lens with a 35mm equivalent focal length of around 20mm.
Auto Aperture: The 10mm is assembled with a CPU chip and motor which the photographers can adjust the aperture via the camera body.
Zero Distortion: Being the second MFT lens in the line-up of Zero-D, it retains excellent performance on the optical distortion control, which is commonly found in ultra-wide-angle lenses.
10-Point Sunstars: Designed with five aperture blades in the 10mm f/2 Zero-D MFT, photographers can create perfect and fancy 10-point sunstars by stepping down the aperture.
