FotodioX LM-FXRF-PRN Reviews

Amazingly good

By Jos Luis
Rated 5 out of 5
Date: 2021-07-25

Mine wasn't working great at first. I reached the people at Fotodiox and they kindly recommended for me to update to the latest firmware which is easy as can be. After that it works amazingly good and just like a charm. Very very fast focusing -of course not as fast as native Fujinon lenses- but amazingly fast on my X-T4 with a Leica Summaron 35mm 3.5. It has new features that give these kind of legacy lenses new life and possibilities. I can now focus extremely close with my Summaron and it works fast enough for street action and snapshooting all around. I am really amazed by this adapter.

Works perfectly with Nikkor 50 and 85 mm

This is my 3rd review of the FotodioX Pro PRONTO Adapter. I am completely satisfied with the ability of the PRONTO to add both my Nikkor 50mm 1.4 G and Nikkor 85mm 1.8 D prime lenses to my Fuji XT-2 kit. It struggled with my Nikkor Micro 105mm 2.8. It did not work with either of my Nikkor tele lenses. I would have rated the PRONTO 5 stars if it would have consistently focused my Nikkor 105mm. In summary, if you have several PRIME Nikkor lenses then this is an excellent purchase of a well built adapter.

Works on Micro Nikkor 105mm 2.8 & Nikkor50mm 1.4

My Fujifilm XT-2 focused with both primes. As per the FotodioX website the PRONTO Adapter prefers primes; I found it to struggle with my zooms. I will continue to experiment with various settings and add a Nikkor 85mm 1.8 in a possible update.

It Works Smoothly On Nikkor Prime Glass

The FotodioX Pro PRONTO Autofocus Adapter worked as advertised on my Micro Nikkor 105mm 2.8 and my Nikkor 50 mm 1.4 prime lenses. It struggled with both of my zoom lenses. I needed to purchase the FotodioX NIK-L/M adapter for my Nikkor glass. The FotodioX website denotes both of these cautions in the products description details. Thus far my greatest success has been in bright sunshine; I have not tested the unit with flash photography. When I have secured proper photos I will add them to this review.

Iffy on my first gen X-Pro1

When it worked, it was just as described. I've unfortunately gone through two of these. The first one went dead after a day of use, whereas the second one prompts my X-pro to flicker on and off, rendering the camera unusable. All in all, a great concept, but your mileage may vary depending on your model of Fuji.

It Sorta Works

I should have known better. Autofocus it a difficult trick even when executed by the same team of engineers. We shouldn't expect an aftermarket autofocus device to work perfectly. This one doesn't work perfectly and for some of us, near perfection is an autofocus requirement.

When the camera is off it does not send any power to the lens. The adapter does not pull any power when the camera is off. It does work with a single autofocusing modes, including face detection.

The product description (LM-FXRF-PRN) state Leica M to X mount adapter but in Q&A the users are taking about Nikon Lenses. Is there a mismatch somewhere?
Asked by: Harvindar
The good thing with this adapter is that you can use different mount lenses with a dedicated Leica M adapter. For instance, you can use a Contax/Yashica lens like the Zeiss Planar 50mm 1.4, which I use with this adapter on my Fuji X-T4, then mount the Planar into a a C/Y to Leica M adapter and then mount it to the Pronto adapter. Sounds complicated but it's not and it works very good. As long as you don't exceed the maximum 1.5lb weight this Pronto adapter can handle you will be fine.
