Fringer EF-FX Pro II Lens Mount Adapter—A Mini Review

The Fringer EF-FX Pro II Lens Adapter allows you to easily and quickly mount Canon EF and EF-S mount lenses to a Fujifilm X Mount camera body. It also works with some, but not all, third-party EF and EF-S mount lenses.

I’ll be the first to admit that this review will likely only prove compelling to a relatively small subset of camera owners. Just to bring you up to speed, ignoring all of the noise and hoopla that surrounds the admittedly great mirrorless camera offerings from Sony and Canon in late 2020 into 2021, there are many photographers as well as cinematographers and videographers who have bought into the Fujifilm X Mount series of cameras. These would most recently include the Fujifilm X-T30, Fujifilm X-T3 and Fujifilm X-T4, and could include the older Fujifilm X-T2 and Fujifilm X-H1.

The Fringer EF-FX Pro II Lens Adapter also features an integrated electronic aperture ring control so you can still grab the ring at any time to adjust exposure.

All of these cameras are very good, and the more recent X-T3 and X-T4, which share the same sensor, are definitely the most video/cinematography capable. The X-T3 and X-T4 both boast the same innovative APSC/S35 X-Trans CMOS 4 sensor and a host of video-friendly features including internal 4K 60p 10-bit recording at up to 4K DCI resolution at up to 400Mbps; HDMI output; a usable, if not great, continuous AF system and a host of other videocentric tools and functions. Fujifilm cameras are also a bit different than their Canon, Sony and Panasonic competition in that the bodies are smaller and more compact and the interface is less “computer-ish/menu driven” with actual mechanical dials to select shutter speed, ISO and a host of other settings.

The Fringer EF-FX Pro II Lens Adapter features a high-quality CNC machined Stainless Steel mount, allowing the use of larger and heavier (within reason) EF mount lenses securely.

Fujifilm’s color science also represents a nice alternative to the standard Sony and Canon color science with pleasing skin tones especially. Fujifilm sells a companion line of excellent lenses, the still photography-oriented XF series as well as a two-lens set of cinema lenses known as the MKX series. The XF lenses, or at least my take on them after owning three and having rented and borrowed several others, is as follows:

  1. The lenses are sharp and make flattering images.
  2. The color, contrast, flare suppression and CA compensation are really good.
  3. The lens lineup is reasonably priced.

Many of us Fujifilm owners still own or recently owned other camera platforms, and out of that group, the owners of Canon systems seem to be the most common. Makes sense as Canon has been the best-selling DSLR lineup for years and has even recently begun introducing new mirrorless models that are very good and sell in large numbers. That said, the Canon EF lens mount is easily the most common one in the world with millions and millions of EF mount lenses on the market. Those of us who own Fujifilm cameras and EF and EF S mount lenses have been looking for a quality lens adapter that would allow us to use our Canon lenses on our Fujifilm cameras.

I’ve been using the original Pro version of the Fringer adapter for the past two years. The Fringer EF-FX Pro II Lens Adapter is the new updated, improved version with a more precise and snappier AF response over the original.

Fringer EF-FX Pro II Adapter

Enter the Fringer EF-FX Pro II lens adapter. I also own the original Fringer Pro adapter that was introduced about two and half years ago that functionally accomplishes the same thing—it lets you mount EF mount lenses to your Fujifilm X-mount cameras. At $349, this isn’t an inexpensive eBay no-name adapter.

The big deal with the Fringer EF-FX Pro II is that it sends and receives AF commands from the Fujifilm X Mount cameras and translates those commands into language that your EF and EF S mount lenses can understand and deal with. There are lots of competing lens adapters for the same mounts, but in my experience, the AF performance on all but the Fringer Pro or Pro II is pretty substandard. Based upon my recent testing, the AF responsiveness on the Pro II is substantially more accurate than the original Pro. The other feature that both adapters offer is a dedicated electronic aperture ring since EF and EF S Canon lenses have no aperture rings on the lens barrels. Of course, you can map the aperture function to a dial on the rear of your Fujifilm camera, but many of us instinctually reach for a physical aperture ring when shooting. The Fringer EF-FX Pro II is excellent for shooting under pressure.

It was very convenient to utilize my basic workhorse video lens for my Canon C200 and 300 MKII on the small Fujifilm X-T3 body with excellent results.

This is a brief review because of space but also because the Fringer EF-FX Pro II is a simple device. It’s firmware upgradeable and the company is constantly adding new lenses to its lineup of supported optics. I see a lot of traffic on Fujifilm boards asking, “Will the Fringer work with my XYZ brand EF mount AF lens?” The only way to know that is to check the constantly changing list of supported lenses here on Fringer’s web page. It supports a lot of lenses, but not every brand and variant, even within the Canon lineup. Most of the popular Canon lenses are supported and a good amount of the third-party lenses too.

Functionally, using my Canon EF and EF S lenses with the Fringer is pretty much the same as using my Fujifilm XF lenses. The AF, especially on the Pro II, is noticeably improved. The fit on the adapter to the Fujifilm body and from the EF lens to the adapter is tight and precise—no slop here. My main video cameras are the Canon C200 and C300 MKII, so I own over a dozen EF and EF-S mount Canon lenses. It’s nice to be able to use the same lens on my pro Canon video cameras and my three Fujifilm X-T3 bodies.

Generally, my Fujifilm lenses are smaller and lighter than my Canon EF lenses, like this EF 24-105mm f/4.0 IS II, but the Canon is rugged, well-built and sharp. But, most significantly, Fujifilm doesn’t make this focal length zoom lens, although they do make an XF18-135mm, but in my experience, it’s less sharp than this Canon lens.

Fringer EF-FX Pro II Adapter Pros

  • Lets me use EF lenses I already own and have paid for with two separate camera platforms.
  • The adapter is very easy to use.
  • The fit and finish on the adapter and fit to camera body and lens are excellent.
  • AF function is good and even better with the advent of the Pro II adapter.
  • Having a physical aperture ring on the adapter is more convenient than using a dial on camera.

Fringer EF-FX Pro II Adapter Cons

  • It’s $349. Not outrageous, but not inexpensive either.
  • If you own third-party EF mount lenses, they may or may not work with the Fringer Pro II.
  • I found updating the firmware takes multiple tries; it’s not simple and straightforward.
  • AF performance is good, but compared to Canon or Sony’s latest, the Fujifilm AF isn’t as good—not the fault of the Fringer, just endemic to Fujifilm.
  • AF performance gets noticeably poorer when underexposed.
I liked the original Fringer EF-FX Pro enough to have recently paid for this Pro II version. I only just received it, but on one shoot and in testing, it’s proving to be a good investment for those of you who own Canon glass that you’d like to use on your Fujifilm cameras. For third-party EF lenses, check the Fringer website for compatibility with your lenses.

Is the Fringer EF-FX Pro II for You?

If you own a Fujifilm XF mount camera and want to use your EF and EF S mount lenses on it, it’s by far the best choice available. If you only want to manually focus and don’t care about AF, save your money and buy one of the inexpensive passive EF to X mount adapters on the market. The Fringer is a niche product that works quite well for its niche audience. For me, it’s been a money saver since I haven’t had to buy a dozen XF lenses to replace all of my Canon glass. Your mileage may vary.
