I said something in my Is $5,000 A Bargain or Bust? article that caught a couple people’s attention. In regards to the upcoming fixed-lens GFX camera, I stated, “I really hope for conversion lenses—both wide and telephoto—like the X100-series has. I highly doubt that the WCL-X100 and TCL-X100 will work on it (although it would blow my mind if they somehow did), but something similar should be made for the GFX100RF.” I received two messages from people wanting to further discuss the idea that the wide and telephoto conversion lenses for X100-series cameras might be compatible with the upcoming medium-format model.
Just to be clear from the top, I’m highly skeptical that the WCL-X100 and TCL-X100 will be officially compatible with the GFX100RF. It’s possible that they might be, but that seems like improbable engineering. I don’t think Fujifilm designed the lens on the new camera to be compatible with those two conversion lenses. More likely—if there are conversion lenses—new ones will be designed specifically for the GFX camera. But…
There’s a strong likelihood that you could actually use those two conversion lenses if you want to. Now, the camera is unlikely to account for and fix the distortion (unless the engineers programmed it to). There’s a good chance that the conversion lenses won’t cover the whole frame, or—if it does—there could be strong vignetting and soft corners. But maybe it won’t be as bad as you might think. For example, Pentax Auto-110 lenses, which are tiny, cover the APS-C sensor. The Helios 44-2 lens, which is for 35mm cameras, fully covers the GFX sensor. So there is a possibility that the WCL-X100 and TCL-X100 conversion lenses will cover most or maybe even all of the GFX sensor.
If they don’t, that may not be a big deal. Using a different aspect ratio will likely crop out whatever isn’t covered. If the conversion lenses cover almost all of frame, then the 3:2 ratio might be all you need. If the coverage isn’t quite that good, 16:9, 65:24, and 1:1 should do the trick. Or, with 100mp to work with, a simple crop should do—I could see using the teleconverter lens in conjunction with the in-camera digital teleconverter, which would crop out whatever isn’t covered.
The real question is if the adapter ring on the GFX100RF will be the same size as the X100-series. My guess is no. Most likely it will be larger on the GFX—I think that’s a pretty safe assumption. In the unlikely case that it is the same size, you’d be able to just screw on the conversion lenses just like you would on the X100VI. Much more likely, you would need a step-down ring to attach the conversion lenses. This would have (at least) two side effects: less coverage of the sensor, and more close-focusing capabilities—maybe even macro—like using an extension tube.
My hope is that Fujifilm releases conversion lenses for the upcoming GFX100RF. If they don’t, or if they do but they’re unaffordable or difficult to find in stock, then adapting the WCL-X100 and TCL-X100 should be possible; however, it may not be ideal. There will certainly be some vignetting and soft corners, and they probably will not cover 100% of the GFX sensor, among other potential issues. But, technically speaking, it should work. If I do purchase the upcoming camera at some point in the future, I’ll be sure to test it out and report back to you what I discover.
The Fujifilm X100VI—the most in-demand camera of 2024—has a fixed 23mm (35mm full-frame equivalent) f/2 lens. It’s not an interchangeable-lens camera, which limits its versatility; however, Fujifilm has provided a couple of options to increase its flexibility. First is the built-in Digital Teleconverter, which is a zoom-by-cropping. Second, Fujifilm offers two conversion lenses—a wide-angle and telephoto—that screw onto the end of the fixed-lens. We’ll talk a bit about both of these solutions in this article, but mostly we’ll focus on the two conversion lenses. Specifically, I will answer this question: is the Fujifilm X100VI combined with the WCL-X100 II and TCL-X100 II conversion lenses a practical small kit for travel photography?

One thing that I love about the Fujifilm X100VI is its compactness. The camera is small enough to fit into a large pocket, and its lightweight enough to carry around all day without being burdensome. The photographs that the X100VI produces straight-out-of-camera are incredible, and can be very film-like. I’ve said many times that this is my desert-island camera—if I could only ever have one for the rest of my life, it would be the X100VI. But, the fixed-focal-length lens is somewhat limiting, so I often suggest that it pairs well with an interchangeable-lens body. I will always bring the X100VI along with me when I travel, but I will almost always have another camera, too.
The Digital Teleconverter helps to make the X100VI more versatile. The 50mm (full-frame equivalent) Digital Teleconverter produces a very usable 20mp image, while the 70mm (full-frame equivalent) Digital Teleconverter produces a much less usable (but still usable for social media) 10mp image. I use the 50mm option somewhat regularly and don’t think twice about it, but I rarely use the 70mm Digital Teleconverter because it is more for emergency-use-only. This does add some versatility, but only a little.
By screwing one of the two conversion lenses—WCL-X100 II and TCL-X100 II—onto the end of the fixed-lens (where the filter adapter attaches), you essentially turn the X100VI (and the older X100 series models, too) into an interchangeable-lens camera. The WCL-X100 II has 0.8x magnification, turning the 23mm lens into 18mm (28mm full-frame equivalent). The TCL-X100 II has 1.4x magnification, turning the 23mm lens into 50mm (full-frame equivalent). Interestingly, there is actually a small focal-length difference between the TCL-X100 II and the Digital Teleconverter, despite that they are both supposedly 50mm equivalent—the TCL-X100 II is actually slightly more telephoto than using the 50mm Digital Teleconverter. I didn’t notice any reduction in image quality when using either conversion lens (amazing!); however, the distortion can do some weird things, which you are likely to only notice when photographing brick or tile walls.
Probably the largest drawback to the two conversion lenses is that they add noticeable size and weight to the camera. The WCL-X100 II is 1.5″ (long) x 2.2″ (diameter), and weighs 0.33 pounds, which isn’t terrible. The TCL-X100 II is a little larger and heavier: 1.8″ (long) x 2.8″ (diameter), and weighs 0.39 pounds. While the WCL-X100 II is a little less inconvenient to have attached, I personally liked the TCL-X100 II a little more. I feel like the conversion lenses contradict the camera’s philosophy (one-camera-one-lens; small/lightweight) to a degree, but at the same time, they do make for an extremely small and lightweight kit. I carried both conversion lenses and the X100VI in a Peak Design Sling, which was an amazingly compact kit for travel!
Fujifilm X100VI + WCL-X100 II (28mm full-frame equivalent)

Fujifilm X100VI + TCL-X100 II (50mm full-frame equivalent)
Fujifilm X100VI + TCL-X100 II + Digital Teleconverter (70mm full-frame equivalent)
You can combine the Digital Teleconverter with the conversion lenses to increase the versatility even further, achieving 28mm, 35mm, 40mm, 50mm, and 70mm (full-frame equivalent) focal-lengths without resorting to the 10mp crop. I didn’t find the Digital Teleconverter combined with the WCL-X100 II lens particularly useful, personally; however, I did utilize the Digital Teleconverter a handful of times with the TCL-X100 II lens. I think it would be interesting if Fujifilm offered a 0.7x magnification (24mm full-frame equivalent) WCL option and a 2x magnification (70mm full-frame equivalent) TCL option in addition to the two they already have—I think this four lens (plus the 23mm fixed lens) kit would be extremely compelling for travel photography, if it were available.
I was invited to be a part of Fujifilm’s Create With Us event in Austin, Texas, last month. It was such a great time, and it was wonderful to meet many of you in-person. The only camera that I brought along with me was my Fujifilm X100VI, plus I had the WCL-X100 II and TCL-X100 II conversion lenses. I left the interchangeable-lens models at home. It was so nice to have a compact three lens kit—which stretched into a faux four lens kit utilizing the Digital Teleconverter—that all fit into a small sling bag. When you travel, oftentimes less is more, as space is a premium.
It was good to have three lens options available: the fixed lens (23mm), WCL-X100 II (18mm), and TCL-X100 II (32mm). There were definitely times when each came in handy. While the WCL-X100 II was a little less detrimental to the X100VI experience than the TCL-X100 II, I found myself using the TCL-X100 II more. I don’t know that either of the two are essential. For the most part, one can take a couple steps backwards instead of using WCL-X100 II, and one can take a few steps forward (or utilize the Digital Teleconverter) instead of using the TCL-X100 II. Obviously that’s not always practical (or the same result), so having the conversion lenses available was appreciated.
I think the conversion lenses are an interesting concept. Having used them on this one trip, I was left both impressed and confused simultaneously. I utilized them a lot more than I think I would have if I had not been testing them out for this article. If someday I did buy them, they’d likely only get occasional use; however, for those occasions when they do come in handy, it’s great to have them available, as they’re pretty darn good. More than anything, I think if you’re a bit nervous to pack light for fear that you’ll miss out due to not having the “right” lenses available, the two conversion lenses will give you a bit more confidence. Even if they’re largely left unused in your sling, it’s probably still better than lugging around a bigger and heavier bag with a larger body and a couple lenses to go with it. In that sense, the two conversion lenses are completely worthwhile accessories to go along with your X100VI camera.
