Huge Vignette

Purchased for my z6, upon arrival and testing there was vignetting covering 40% of all images taken. Unfortunate.

About Viltrox EF-Z2

Under the umbrella of innovative camera accessories, the Viltrox EF-Z2 Speed Booster stands out as a game-changer for Nikon Z-mount mirrorless camera users. This device is specifically designed to bridge the gap between Canon EF-mount lenses and Nikon Z-mount cameras such as the Nikon Z6, Z7, and Z50.

The EF-Z2 Speed Booster not only expands your lens options but also retains the native autofocus (AF) and stabilization performance of your lenses. It supports Nikon's Face and Eye Detection AF, ensuring sharp and precise focus on your subjects.

One of the key features of this speed booster is its 0.71x equivalent focal length adjustment. This adjustment is based on the original focal length of your lens, allowing for a wider shooting range and more creative flexibility.

In addition to expanding your lens options, the Viltrox EF-Z2 Speed Booster also enhances your camera's aperture by 1 stop. This built-in optical extender allows for better background blur, highlighting your subject and enhancing the overall image quality.

The EF-Z2 Speed Booster is compatible with a wide range of EF lenses, from 8mm fish-eye lenses to 800mm super telephoto lenses, as well as micro lenses and tilt-shift lenses. This versatility increases the practical value of your lens group, making it an economical and practical addition to your photography gear.

The seamless docking of the camera body and lens ensures fast and smooth autofocus. The built-in metal contacts and data chip support lens image stabilization, effectively avoiding blurred imaging issues caused by shaking.

The Viltrox EF-Z2 Speed Booster also features a matting treatment on the inner wall to efficiently absorb reflected light, preventing stray light, glare, and light leakage. The ergonomic release button and the option for firmware upgrades further enhance the user experience, making this speed booster a must-have for Nikon Z-mount mirrorless camera users.
