[for Nikon F]
FULL MANUAL LENS, no electric contacts→no auto focus→no image stabilization, require more exprerience with Manual Exposure.
No matter how good autofocus is, there are still times when manual focus is the better shooting option. When used in the right scenario, it gives a photographer more control over the photo, and in some cases, achieves effects that arent otherwise possible in autofocus mode.
Optical Structure
The Lightdow MF 135mm F2.8 lens delivers captivating and beautiful background blur for every photo, along with excellent contrast and sharpness in the in-focus areas. Optimized lens elements, including 2 Extra-low Dispersion (ED) glass elements, effectively eliminate chromatic aberration. This control extends to areas with color fringing in front and behind the focus point, even in challenging scenarios like branches. The lens achieves exceptional clarity and high resolution across the entire frame, even when wide open.

Low dispersion lensThe lens consists of six optical lenses in six groups, and the Lightdow low-dispersion lens (ED) is used to minimize light scattering according to the wavelength of light, ensuring color difference in not only the central part but also the peripheral part of the image. |
F2.8 bright large apertureThe F2.8 large aperture design ensures a swift shutter speed in indoor and low-light environments to complete clear shots, and the shallow depth-of-field effect brings out the subject for softer, more beautiful images. |
The ideal telescope lensThe 135mm F2.8 lens is a full-frame telescope-level manual focus lens. It provides a sharp sense of color and a soft sense of defocus, and is suitable for a variety of uses such as portrait photography, night photography, wildlife photography and photo pictorial photography. |
