p.2 #2 · Boryoza GF-NZ Auto Foucs Lens Adapter -- can someone explain?
I ran a brick-wall test to see whether the built-in distortion corrections for the GF lenses still work when the lenses are used on a Nikon body via the adapter. I tested the 23mm, 30mm, 45mm, 20–35mm, and 45–100mm.
In Adobe Camera Raw and Lightroom, the corrections are not working. When the lenses are mounted on the Nikon, the Lens Corrections panel shows “Built-in,” but it does not detect the lens make/model the way it does on a GFX body. Somewhere in the hand-off, the embedded profile isn’t coming through.
Capture One behaves differently. You can manually select the correct GF lens profile from the dropdown, and the distortion correction works properly for all the lenses except the 20–35mm, which isn’t listed and falls back to the built-in data.
For what it’s worth, the fixed-focal-length GF lenses have very minimal distortion, so the lack of correction isn’t a big deal with those. But the zooms—especially the 20–35 and 45–100—show noticeably more distortion, so proper profiles matter a lot more there.
My guess is that the EXIF isn’t being passed correctly, or Adobe’s pipeline is expecting a Fuji-body + GF-lens combo before it enables the corrections. With the Nikon + GF adapter in the mix, it seems to break the chain.
Hopefully this is something that could be addressed in a future firmware update.

Nice shot with the Bald Eagle,
how is your experience so far with the adapter ?
I own the GF 500mm and got a Nikon Zr, I suppose it works well since you posted new picture, seriously considering it instead of buying a Z 400mm 4.5
Thanks for the kind words, I'm thrilled with the adapter on the z8 especially since I was already invested in the GFX system with multiple primes including the GF 500mm and 1.4x TC. Access to higher, blackout-free fps and solid AF on the z8 for birds particularly has been my main interest. Since you already own the GF 500 and probably others, it makes a ton of sense to try the adapter out for minimal marginal cost to access prime performance on your ZR, if you're comfortable with the weight on the small(er) body.
My one concern is unknown weather sealing, which is probably true for all adapters, so I take it out only in moderate to good weather, and switch to the z 180-600mm for better sealing. So far build quality feels solid, but I protect it in a bag a bit more than my z-zoom which I tend to sling over my back to carry. I contemplated and rented the z 600 S PF and found it superior to the z 180-600mm, but with the adapter and GF 500 +/- 1.4x TC I've lost interest in adding the z tele primes, if that helps. The GF lenses themselves do not autofocus as fast as the Z equivalents, to be honest, but for my use case even with action shots I am more than satisfied with the tradeoff considering my primary GFX system focus. Interested to hear what your decision is!

I received the Adapter a week ago, so far, it's fine with the Zr.
the GF 500 is not the fastest lens when it comes to AF, but the tracking works great. I would not recommend to buy the GF lens if you don't own it. But having both system and using the Zr more as a video tool. This is worth it! Thanks for the feedback!

Reviving this old thread. I wonder if someone with this Boryoza adapter has the Mitakon 65mm lens and can test it to see if it fits and works? I am really interested in adapting the Mit on my Nikon ZR for some low DoF work. A post on DPReview said the Mitakon doesn't even fit the adapter which is a bit odd as it's the same mount. The only problem I can think of is the slightly protruding black shim on the Mitakon that might prevent it from properly mounting on the adapter. Would be great if someone having both of these can give it a try.

Just tried this combo again with the Mitakon 65, Boryoza G-Z, to Nikon z8 and surprisingly can confirm it does *not* work.
There seems to be an internal spacing issue that generates a grinding metal on metal sound, even when depressing the Boryoza lever to release the lens. I ran into it before and thought it was just a weird alignment issue since every other GF lens fits perfectly and I didn't force the issue at the time, but if DPReview is reporting the same on a thread then I guess it's an issue with the lens and adapter combo.
Here's a photo and if you zoom in you can see the spacing between lens and adapter. Weird...

For what it's worth, their Fuji X > Z adapter has gotten really spotty reviews. Curious to hear the results but I wouldn't expect much.
It works, but it was a suboptimal solution for me. Some lenses worked better than others, but the bigger issue was that Fuji's lens correction data is baked into RAWs, so it doesn't transfer when you adapt the lenses.
