Have reasonable expectations.

It works... barely... you can use manual focus with this adapter. It will try to autofocus the lens even if manual focus is selected on the lens and the camera. It also will fault if no electronic contacts are found and report a lens error to the camera making the camera unable to shoot fully manual lenses. But it does autofocus with official canon lenses, and only official canon lenses. Most canon prime lenses will cover the sensor with noticeable vignetting and softness in the corners but I find most lenses plenty useable for portraiture, especially L series lenses. My 50 F1.4, 100mm F2, and 135mm F2. all work particularly very well and I purchased all of them for a fraction of what a single GFX lens cost. Given the lack of autofocus fast lenses on the system, this is quite valuable in low light situations. So despite it's shortcomings it's worth the cost.

Very nice adapter

By SHELLEY Q.

Excellent product. Works very well with Canon EF lens.

Where versatility meets functionality, the Viltrox EF-GFX Mount Adapter is a must-have for photography enthusiasts and professionals alike. This innovative device enables seamless integration of Canon EF or EF-S-Mount lenses with FUJIFILM G-Mount GFX cameras, expanding your photographic possibilities.

Constructed with precision, this adapter boasts inbuilt electronic contacts and robust metal bayonets with surface plating treatment, ensuring durability and longevity. It's not just about sturdiness; the Viltrox EF-GFX Mount Adapter also brings advanced technology to your fingertips. With its autofocus (AF) function, you can capture sharp, high-quality images effortlessly.

The adapter's compatibility extends to official Canon lenses, including prime lenses, making it an excellent tool for portraiture. Despite the occasional vignetting and softness in the corners, most lenses deliver satisfactory results, especially when paired with L series lenses.

In low light situations, the adapter proves its worth by allowing the use of fast lenses, a feature currently lacking in the GFX system. Moreover, the firmware of this adapter can be upgraded via a USB port, ensuring it stays up-to-date with the latest technological advancements.

Please note, while the adapter does allow manual focus, it may attempt to autofocus the lens even if manual focus is selected on the lens and the camera. Additionally, it may report a lens error to the camera if no electronic contacts are found, potentially limiting the use of fully manual lenses.

In conclusion, the Viltrox EF-GFX Mount Adapter is a valuable addition to your camera gear, bridging the gap between Canon EF lenses and FUJIFILM G-Mount GFX cameras, and unlocking a world of creative potential.
