A typical phase contrast image has a neutral background and surrounding with varying contrast where light is altered by the specimen (Figure 1). Two very common effects seen in a phase contrast image are halo and shade-off patterns. These occur when the infinite-conjugate focal point does not match for the specimen and background. Although these are common and expected in phase contrast images, they diminish the appearances of details. In general, a bright phase contrast halo is typically visible at a boundary between strong and weak specimen features. These halos are evident due to the circular phase-retarding rings. Specialized objectives, known as apodizing phase contrast objectives, are manufactured to reduce this phenomenon.

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.

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.

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.

The Laowa 7.5mm f/2 MFT is compatible with Panasonic, Olympus & Blackmagic cameras with Micro Four Thirds lens mounts. The lightweight version is specially designed for drones & gimbal usage.

The phase contrast technique translates extremely tiny variations in phase into a noticeable and corresponding amplitude change, and is evident in the difference of contrast in Figure 1. The most important concept of the phase contrast microscope design is the isolation of wavefronts, both surround (undiffracted) and diffracted, that arise from the specimen. To differentiate intensity profiles between a specimen and its surroundings, the undeviated light must be reduced and the phase retarded by a quarter-wave retardance. A brightfield illumination microscope can be upgraded to a brightfield-phase microscope with the introduction of two components to the optical train. For additional information on the brightfield technique, please read Optical Microscopy Application: Brightfield Illumination.

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.

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.

Phase contrast was first utilized and described in 1934 by Frits Zernike. This optical microscopy technique enhances the contrast of transparent specimens, yielding high-contrast images of living cells, microorganisms, and other samples. The main advantage of the phase contrast technique is that living cells and tissues do not need to be killed, fixed, stained, or prepared in any way and can, in turn, be examined in their natural state. Analyzing and recording the dynamics of intricate biological processes becomes very easy with phase contrast optical microscopy.

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.

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.
