The Ultra Wide Angle Lens is one of the most important lenses that every photographer can have in his camera bag. There are many costly ultra wide angle lenses in the market, varying in price from hundreds to a few thousand dollars. However, these UWA lens are not perfect. They suffer from dramatic barrel distortion, poor peripheral sharpness or huge physical size. Venus therefore spent a lot of time to come up with a design which is truly perfect and overcome the frustration of photographers. That's where the LAOWA 12mm f/2.8 ZERO-D comes from. Ultra Wide Angle lenses in the market tend to suffer an optical distortion rate from 2 to 5, which causes straight lines to bend. The LAOWA lens features a *close-to-zero distortion rate that you can barely notice with your eye. (* The aforementioned close-to-zero distortion rate is measured from shooting objects at infinity focus. The distortion rate may vary for shorter object distance. Only Optical Distortion (Barrel/ Pincushion/ Moustache) is covered here.) The LAOWA 12mm f/2.8 Lens covers an ultra-wide 122° angle of view for you to create an outstanding landscape or architecture that no others can compare to. Shooting interior s will also become much easier. Your house will become spacious and impactful in your photo even if you are shooting a small area. Do not forget, this is also perhaps the world's widest rectilinear f/2.8 lens. Optical performance is what Venus Laowa will never compromise. The optical design features a 16 lens elements in 10 groups with 3 Extra-Low Dispersion Elements and 2 Aspherical Elements.

Weight is merely 1.34 lbs (609g), making the LAOWA Lens an every-day lens. It is really small compared to other Ultra Wide Angle lenses in the market.
