Viltrox NF-M43X Focal Reducer SpeedBooster - with Video Samples

[@joeprete7424]

+NavinReviews ...There is a screw to adjust the element, to get correct focus at infinity. There's a ScrewDriver (and Allen Key) in the case. Use the Phillips Head Screwdriver, to adjust the Element! Very few Adapters are made for Nikon to M4/3rds, and even fewer, of the SpeedBooster Adapters. It's something about the Nikon Mount, and less demand for them. Many more are made for Canon to Sony Mounts, and given the price difference between Vitrox and Metabones, we are quite lucky to have these. I paid $75.99 on Amazon (US), and the Viltrox Quality is very high! For those that just want to adapt their lenses to Micro 4/3rds, a plain Adapter is available for less than half the price. K&F Concepts and Neewer brand also make plain Adapters for less than $25.00 their quality is also quite good. Be aware that you will lose all Auto Functions, but since people interested in using these are real Enthusiasts, this is not a problem. Someone mentioned a different version (below), but mine is "Viltrox NF-M43X 0.71X" The Nikon DX Lenses will work better! Also, I see a YT Video "How to Fix Speedbooster/Focal Reducer infinity Focus" by Aleksandar Roman. Watch it, and have patience. You will get there! A Great Website for Micro 4/3rds is www.mu-43.com ...Joe Prete

[@joeprete7424]

Yes, The Video Explains it Exactly, even though it is a Sony, THE DESIGN IS THE SAME. BE VERY CAREFUL, NOT TO SCRATCH THE ELEMENT, AND MARK THE POSITION VERY CAREFULLY. IT IS NOT HARD TO DO, JUST EXERCISE CAUTION !!! ...Joe Prete

Ya that video is $$$ it can focus to infinity.

[@joellemorris5684]

Very good video. Thanks. To make things very clear, I have one question: with a Sigma 18-35 lens and a GH5 (that i have not yet bought) and the Viltrox NF-M43X speedbooster, will the aperture information be visible in the viewfinder of the GH5? will the autofocus of the lens work? thanks for your answer.

[@ojt4438]

There's no electricity in this booster so aperture won't show in camera and autofocus doesn't work. Also lens image stabilizers won't work with this booster.

[@corrbox2]

How much time did it take you to learn how to use this Viltrox adapter on your Panasonic Lumix GH5 with the Nikon F mount lens, plus how many lenses do you use with the adapter? Thanks for your review. You made me very interested in this adapter based on your review. Please keep up the good work!

[@navinr9558]

Sorry for the late reply I used it with multiple rokinon lenses and it's easy.

[@parker_films]

I have the GH5 + Viltrox NF-M43X + Sigma 18-35 set up, How do you keep your subject in focus when moving around, forward and back when filming at a function at night?

[@navinr9558]

Use focus peaking

[@uchihaXshinoda]

hi, great video! i wonder if you can help me out. what does the the appeature wheel on the viltrox reduce/ incrwse the apeature of the lens to? for example a sigma 18-35 1.8 paired with teh viltrox, what does it become?

[@marianopeluso684]

Thanks for this video, it's the adapter okay for Nikkor AF-S 70-300mm ED VR?

[@jeremyclimbs]

Do you know where to find an autofocus version of this speed booster for Nikon lenses? I have looked everywhere, so sad so bad

[@djcrash77]

I believe Viltrox makes one

[@ravebrave8866]

Thanks Kolbi

[@hannessassenberg7341]

Can you also open the aperature through the camera without touching the ring on the lens?

[@navinr9558]

This cannot be done with Nikon version but can be done via canon version

[@logiknotlogic6586]

Hey I have this old Nikon lens that has an aperture of f5.6. How much more light will this adapter be able to bring in and around how much will the f stop reduce from 5.6? Also regarding the aperture control on the adapter, it controls the aperture of the lens right? Thanks!

[@bogdannalyvaiko9982]

I see that with SB Viltrox NF-M43X focus is better, than SB Viltrox EF for Canon

I just bought the Viltrox adapter NF-M43X. Indeed it takes nice pictures with nice bokeh (I tried with the Nikon 1.8/85 mm and the Nikon 2/35 mm. But at infinity the lens cannot focus. Does anyone have a tip about this?

[@navinr9558]

I guess it's just the small lens in the adapter, you need to tighten it a bit by rotating it.

[@joellemorris5684]

@@navinr9558 maybe try to follow this method: kzbin.info/www/bejne/eYLCgXmDgdShprc

[@mangesh2458]

Thanks for the video!

[@JayCarver]

I have this viltrox and using it with the AF NIKKOR 35mm f/2D and panasonic gh5s. When I turn the aperture ring on the viltrox adapter there's no change in light. Am I missing something?

[@navinr9558]

Please make sure that the lens aperture clip matches with the speedbooster.

[@JayCarver]

@@navinr9558 they did. I decided to return it. I think it was defective. I will try ordering it again. Maybe I got a bad unit.

[@illiakrasnoshchok5240]

Hey, great review, thanks! I assume there is no vignetting on sigma 18-35mm with this booster, right?

[@navinr9558]

Yes no Vignetting at all.

[@arbbell]

Does it have any play? Ive been hearing and seeing tons of bad stuff on the ef-m2 version. from massive play to weird haze and extreme vignetting and infinity focus issues. since this is the nikon version, does it have any of this stuff?

[@navinr9558]

Arbel Biton I didn’t see any issues with play but it has infinity focus problems.

[@GlennUpgraded]

@@navinr9558 but can easily be fix by rotating the glass element on the adapter like the ef-m2?

[@navinr9558]

That's correct

[@brasiossegujja9656]

have you ever tried it on the blackmagic 4k cinema

[@Gopalrahmaniac]

Hi.. i have a nikon d5200 apsc camera and a bunch a Nikon full frame vintage lenses. Can i be able to use this adapter for the above said combination?

[@navinr9558]

Yes you should be able to.

[@divinodayacap3313]

Will this work for Manual Nikon Lenses?

[@debashishsahoo2687]

Which Speed booster is good for canon m50.. vitrox ef m2 or viltrox nf m43x?

[@arnold2603]

Nf m43 is for f mount lens (nikon lens to mft mount)

[@brasiossegujja9656]

am asking how good is it on a blackmagic 4k cinema camera

[@navinr9558]

brasio ssegujja it does work on mft cameras so it should be good on bmpcc 4K.

[@peterlee4544]

Plse present it louder, this will enable viewers not to struggle with their ears. Thks

[@Crawling8888]

Can I also adapt APS-C Lenses with this speedbooster to get good results?

[@navinr9558]

Crawling8888 yes you can

[@Crawling8888]

@@navinr9558ok so did you test APS-C-lenses? Are there no problems with sharpness, black shadows in the corners and stuff like that?

[@navinr9558]

Crawling8888 the sigma lens is itself apsc as you know

[@Crawling8888]

@@navinr9558 ah ok thanks! And what is the maximum aperture you use with your lenses? For example if your lense is f2.8, do you also set the speedbooster at 2.8 then?

[@navinr9558]

Crawling8888 no I set it max that’s when you will get f1.2 aperture f1.8 = f1.2

[@przybylskipawel]

Does it reduce maximum F-stop to f/8?

[@navinr9558]

It reduces the Fstop of any lens you adapt.

[@in2theair67]

But no Autofocus with this adapter 🥵

[@dimitrimoonlight]

does it work AF?

[@Flicklix]

No...the adapter does not communicate with the lens or camera body electronically.

[@topcat7091]

Hi Navin, thanks for the video. JUST encase no one else has said it to you already, you can adjust the infinity focus by rotating the glass on the Veltrox adapter until you find the right position. If you LOOK UP a guy called GERALD UNDONE on KZbin, I think he is a Canadian guy, he goes into great detail as to the best way to do this.

[@navinr9558]

Oh yeah i figured it out. :) thanks for the comment.
