The main advantage of aspherical lenses is that they can better correct optical aberrations compared to spherical lenses.

The Standard & Lightweight versions of the Laowa 7.5mm f/2 are now available. They share the same optical design but differ in weight. Both have metal construction, but, we carefully designed and replaced some of the materials to lower the weight from 200 g (Standard) to 150 g (Lightweight). The Lightweight version is specially designed to work with drones.

This lens loves working in dark and difficult lighting conditions. The extreme 110° angle of view and ultra-fast f/2 aperture allow photographers to create impressive astro-photography shots with ease. It also gives photographers a fast wide angle option for low-light, architectural and landscape photography.

An aspheric lens is a lens whose surfaces profile is neither a portion of a sphere nor of a circular cylinder. Since it is not spherical, the conventional production processes no longer apply to making aspheric surfaces. The production of such elements requires a high-end level of production expertise and technology.

The Laowa 7.5mm f/2 MFT is the widest f/2 rectilinear lens ever designed for Micro Four Thirds cameras. Despite the impressive specifications, Laowa has successfully reduced the weight to less than 200 g (7 oz.) and length to only 55 mm (2.16 in.) long. The optical performance and distortion control are outstanding.

This feather-weight lens opens up a new opportunity for photographers to shoot wider coverage with gimbals and drones. Thanks to its compact size, the lens perfectly pairs up with compact Micro Four Thirds cameras as an ideal every-day lens.

Due to its compact, lightweight design, the Laowa 7.5mm f/2 MFT is excellent for Vlog and lifestyle videography, like weddings, travel, music videos, etc. This small lens is a perfect match with your gimbal or stabilizer, letting you shoot videos with ease and efficiency. No need to carry big, bulky and heavy equipment ever again! More video samples can be found on the “Testimonials” page.

Only one aspherical lens is needed for the correction of optical defects, often times with even better results than a combination of more spherical lenses. This technological approach results in smaller diameters, smaller number of optical elements and lighter weights of final systems.

Beyond its small form factor, this lens also features a notable optical design that incorporates two aspherical elements and three Extra-low dispersion elements to control distortion and aberrations for improved clarity and sharpness. The front has a 46mm thread for screw-in filters – offering creative and exposure control for landscape photography.

A few weeks ago the WiFi in my home was updated to an EERO mesh network. Every device in my home easily connected except my sleep number bed.

Please note: the 7.5mm f/2 MFT (standard version) has no electronic connections with the drones/gimbals and therefore, there is no electronic control of the aperture or focus. If you hope the metadata can be saved in EXIF, you are suggested to pick the automatic aperture version.

We are using Taylor Hobson measuring machines as contact profilometer for measuring unpolished surfaces. Luphoscan for non-contact measurement for measuring polished surfaces.

This lens is currently the widest rectilinear lens available for Micro Four Thirds cameras. It gives a field of view equivalent to a 15 mm lens on 35 mm sensors. This allows MFT users to enjoy an impressive 110° ultra wide angle of view for a broad range of shooting. The wide angle of view and ultra-fast aperture are extremely valuable for astro-photography. This lens is super compact and lightweight for casual on-the-go use. A ultra-light version is also available for aerial photography usage.
