7artisans Fixed focal length 7.5 mm F2.8 Fisheye Mark II

The second generation of the 7.5mm F2.8 has been optimized in its optical structure. Single glass with a higher refractive index is used in the front glass group to replace the first generation's cemented glass. The rear group of optical glass is enhanced with HOYA ED glass, which effectively improves chromatic aberration.

The image quality of the lens has been significantly improved. While correcting various aberrations, the field of view angle has also been enhanced. The polishing process of the glass is now more precise and complicated than in the previous generation. The optical structure of the entire lens still consists of 11 lenses, but the total optical length has been shortened, making the lens more compact than before.

The overall appearance maintains the style of the first generation but continues to feature an all-metal body. The 7.5mm F2.8 Mark II adopts a shell oxidation process, and the lens mount color has been changed to electroplated tungsten steel, making it both beautiful and durable. It is newly adapted to the Nikon Z mount, providing users with more choices.

Note: Due to the large shooting angle of the fisheye lens, the hood filter holder will block the imaging, so there is currently no filter holder or hood available.
