Rated 5 out of 5

Solid quality

Solid construction and optics yield crisp images with some adapted lenses. Top that with a brighter and wider field of view. Highly recommended!

Superb Adapter

I was very impressed with the construction and functionality of this adapter. It worked very well on most of my Nikon lenses. Unfortunately, it wouldn't allow aperture change on my 45mm tilt shift lens. This was the lens and NOT the adapter. Doesn't seem a good idea to use a lens wide open only when your goal is to maximize depth of field. The glass in the adapter worked as designed. Very impressed, but had to return it since it had a problem with the t/s lens.

Enhance your photography experience with the Nikon G to Fuji X Speed Booster ULTRA, a cutting-edge accessory designed to elevate the capabilities of your Fuji X camera system. This high-quality speed booster is engineered with an advanced 5-element/4-group optical design, featuring ultra-high index tantalum-based optical glass from Caldwell Photographic in the USA. This innovative design ensures extraordinary optical performance, delivering improved corner sharpness, minimized distortion, and significantly reduced vignetting.

The industry-leading aperture ring on the Speed Booster ULTRA offers a comprehensive 8-stop range with precise markings, eliminating any guesswork and allowing for seamless adjustments to your desired f-stop. This feature is particularly beneficial for photographers who demand exact exposure control in their creative process.

Compatibility is at the core of this versatile adapter, supporting a wide array of lenses including Nikkor G and F lenses, from non-AI to AI lens mounts. This makes it an indispensable tool for photographers looking to utilize their Nikon lenses on a Fuji X-mount camera body, expanding their lens options without compromising quality.

By increasing the maximum aperture by 1 stop and enhancing the Modulation Transfer Function (MTF), the Speed Booster ULTRA allows for faster shutter speeds and a narrower depth of field, perfect for capturing sharp, detailed images even in low-light conditions. Additionally, the 0.71x magnification factor effectively reduces the crop factor of DX-sized sensors, broadening your field of view and maximizing the potential of your full-frame lenses.

The Speed Booster ULTRA is not only innovative but also compact and durable. The detachable tripod foot is compatible with Arca Swiss, Markins, and Photo Clam ball heads, offering stability and versatility for any shooting scenario. Please note, this mount offers manual aperture control and does not support electronic aperture control, ensuring that photographers can make precise adjustments as needed.

In summary, the Nikon G to Fuji X Speed Booster ULTRA transforms your lens collection into a more powerful and dynamic toolkit for your Fuji X camera, making it an essential addition for both professional and enthusiast photographers seeking to enhance their creative capabilities.
