Fujinon Lens on a Nikon mount

[Raphael Biss]

Hello all !
It may sound a bit ridiculous, and maybe a bit of a stupid question,
But is there any way at all to put a Fujinon 1/3 Bayonet lens on a Nikon mount by any chance ?

Even if there's a huge crop factor or focus problems, Has anybody tried it out already ?
I have that lens from a JVC GY HD 100 and would have loved to see what it looked like mounted on a RED ONE with a Nikon adaptor.

I haven't found any adaptors on the market, maybe it's a home made job.

Thank you for letting me know. All the best

Hello Raphael,

I have both, a multi-cam with 12x JVC GY-HD2XX-7XX, and REDs for cinema/music/fashion. Checked every lens that fits ProHD cams. Even from Panasonic 1/3 cams

Straight to the point:
As about Th16x5.5BRMU - trash it! Well, it could be used for web casts or news of some kind... But definitely not with R1. It does it's job as a stock lens that goes with ProHD cameras, and that's it. Terrible CA. Terrible resolution and focus. I use it as a bayonet caps ProHD cams are sometimes very useful (and appreciated by the client), I love them for many reasons. But you have to go for CHE versions, that comes without lens and fit Fujinon 13x/18x/20x or at least Canon 14x to make it more or less serious. ProHD series really and amazingly do the trick of fooling the viewer with it's cinematic look. Especially when shot in 720P24 and mastered for DVD. Outstanding picture! You can even use an adapter for PL-mount lenses...

...But when it comes to S35 format all those lenses do not stand a chance. Even though it's price (13x or 20x) is pretty high. Much more than camera body

The only suggestion that comes up if you still want to marry 16x to R1 - go the other way around - use B4 (2/3) mount (oops! senior members, help me out on that!) together with Fujinon ACM-17 adapter. It might be pricey to buy from Fujinon, so there is a whole lot of other brands, just cheeper. No optics involved, it's a simple mount adapter. It should work fine with focus, you may also power the lens motors from R1 aux 232 port. The only issue is that 1/3 lens will produce a crop even in 2K...

I think the Fujinon lens for the JVC GY-HD*** camera family may have had an "in-air" flange to focal plane distance of about 37mm but I would need to be corrected here. The Nikon F-Mount has a flange to focal plane distance of 46.5mm. The image area from the 1/3" format lenses would be a small circle inside the much larger image frame of the Nikon camera. There would likely need to be an optical adapter made which would restore the flange to focal plane distance so that infinity focus could be achieved. So far as I know, there are none made for the JVC 1/3" ProHD lenses to Nikon F-Mount. The known deficiencies of the 1/3" lens would become more obvious if the image area from this lens is optically enlarged to cover a 35mm frame. There is also the optical correction from a 3 x CCD sensor system to single sensor system to be considered. By the time you had all the engineering done and paid for, you could afford to buy an entire Scarlet and stills lens for it for a far better result.

Right. And technical bit is explained. I suggest you a descent B4 lens for slow-mo and 2K run&gun works.
Or grab some old Angenieux 25-250 with PL-mount. Much better. The one you see on my avatar. It's tricky to operate, but you get used to it. And it covers up to 4K.

Thanks for your replies...
I've had a look at the adapters but I was thinking of something much simpler... maybe take a Nikon ring and somehow stick it to the lens (as I'm never going to use it again on anything else)...
Not sure what that would do though...

Serge, I would love to get myself an Angenieux (they are my favourite lenses).. I just don't have the budget yet. However, if you know a good deal I would be very interested to have a look
Thank you again for your replies !

Raphael. I have a sense I might be missing something. - What camera do you want to mount this lens on to? Is it a Scarlet/Epic, Red One? With the Red One, you might have a few more options for home-rigging something due to the closer setting of the casework to the sensor plane. It is not something I recommend. These cameras are very complex. They have live electrical wiring to the lens mounts. The chances of doing something really fatal to the camera for sake of saving some dollars with a home modification are too great.

Thanks Robert !
I was talking about a RED ONE due to the possibility with the sensor. However, I won't be trying anything with it. Just asking questions if it has been done before.
It does indeed look like it would be a lot of hassle for a very bad result.

I guess I'll just have to put the Fuji lens back on the shelf and forget about it

With the Red one, if you want to shoot with a B4-Mount lens, in "near-to" but not actual 2K, P+S Technik made a RED version of their IMS Mount system and a B4-Mount intermediate adaptor with an optical block for 3 x sensor correction. Fitting the IMS mount to the Red One will void any warranty that might still exist. A version of the IMS B4-Mount intermediate adaptor, albeit more expensive, also included a prism split to an optical groundglass reflex viewfinder with their Evolution eyepiece. http://store.pstechnik.de/home/inte...-ims/ims-for-red-one/#cc-m-product-6019384486 The IMS intermediate adaptors are listed in a sort of crossreference vertical and horizontal column layout on the page. This page is a bit hard to find unless you know where it is. http://store.pstechnik.de/home/inte...s-ims/ims-1-0-mounts/#cc-m-product-6012043986 This illustrates some of the IMS- intermdieate mount adaptors. What is not easily found is that P+S also have some small prime lenses which are 2K-capable which mount directly to the IMS base without need of an intermediate adaptor. They are a fairly gold-plate price though. One little trap with the IMS-Mount system is that the IMS-PL mount intermediate adaptor itself will accept all other IMS intermediate adaptors including another PL Mount. One can inadvertently forget to take off the PL Mount intermediate adaptor and end up making a stack of adaptors which places the lens some 33mm forward of where it should be and you end up majorly confused as to why you can't get any focus except maybe a nose whisker at 2mm distance. Here is an example via SI2K of the image available from an old Standard Definition TV-Nikon 8mm - 125mm Betacam lens with swing-in doubler to 250mm. I like ENG lenses on the SI2K because it is wired to drive them via a standard ENG lens control cable socket. I don't know if your Red has this socket. Don't judge the camera by the colour grade. I am red-blue colour-blind, so the examiners told me when they failed me for an unrestricted private pilot's licence way back when. This lens and a similar range HDCAM Canon ENG lens vignette at 2K at fully wide and again through the zoom range from about 25mm to 35mm. in a faux cinemascope letterbox crop, the vignette can be buried. The 2K pixel count for the SI2K is 2048 x 1152. The pixel size on the SI2K is five microns. I do not know the pixel size of the M or MX sensors on the Red One, so I can't vouch for what area the 2K crop on the Red One actually covers. http://www.youtube.com/watch?v=Uog_t33oAec
