How do you control the aperture in "G" series Nikon lenses ?

no nikon adapters can show apertures, it's merely a small lever in the back of the lens.

well, they can, but it takes a little bit of work and only works for one lens. I have one of the less expensive Fotodiox adapters (~$30?) that I used exclusively with my Sigma 50-150/2.8, and using the AF100's spot meter I calibrated and marked the major f-stops. They're incredibly close, but they are marked... but again, only for that lens.

All quite aside from the original convo, but nonetheless, yeah... plenty of 3rd party manual lenses have aperture rings. Go nuts.

Just to set things straight there is an adapter that shows the stops.
Also positive locking to alleviate any slop in the mount
For the Sony F3 none the less...

Well if you don't want to spend money on an adapter you can always jam something in between the aperture lever and the rest of the mount (like a broken match stick). I've done this before in a pinch. Mainly when I only wanted to shoot wide open on a G lens on a nikon dumb mount. Only issue is you can't control the amount of stop unless you take the lens back off.

The speedbooster has similar markings for Nikon lenses but its an adapter (like the one pictured) from one system to another, the OP is after an adapter to go from Nikon to NIkon but allow him to change the aperture manually.

I cant see how the abaove adapter would genuinely show the F/Stop of the lens accurately?

The scale is adjustable so it can be quickly matched to the lens installed.
I know what the OP is looking for- I was just responding to someones claim that NO adapters show the f-stop on G- lenses-which is not true...
 
Optitek: What kind of adaptor is this and what lenses does it work on?

By the way, Redrock has the Canon line covered with an ingenious little solution. It's kind of pricy though, but it works.

EDV, that is a micro four thirds to canon mount live adapter, its not what you want

i claimed, that no adapter 'can' show the actual aperture reading, yours, while nice as a reference, i wouldn't hold as critically accurate. i'm not saying the adapter is false, just that i would hold such markings with a grain of salt unless i saw proper tests to show that it can be accurate to within a quarter of a stop, between say a f1.4 lens, and a f4 max aperture lens(which, if you have, i will completely recant my hearsay and remark on your fine product), otherwise i wouldn't rely on it for anything where a shot might need to be dead on repeatable. granted, many users don't require that much accuracy and in that case, im sure it's fine.

What... you mean the Redrock Live Lens? Yes, I know that, but they also have version for canon mount cameras.

If I ever need to use the Canon Lenses, there's my aperture solution. Comes bundled with the actual Canon mount.

The adapter is for their specific M2 and M3 35mm adapters to give you control of Canon Eos lenses but its no good for the Nikon you was trying to mount.

Can you go the Canon route?

I think like you Darren, I wouldn't really mind on how accurate that adapter was in the true sense, just so long as I had a rough idea of where I was and honestly Im fine with the Novaflex adapter for declicked iris on Nikon G lenses and pretty happy with the Speedbooster arrangement too. I actually don't see what I can complain about when adapting SLR lenses made for photography to a video camera.

Loved your no nonsense AF100 review back in the day by the way :0)
 
ha, that review video made me not want to post anything on youtube ever again. if you look through the comments it's riddled with fanboys, mostly claiming that i'm an idiot because vari-nd's exist. im long overdue on my c100 review, mostly because it's already accepted that it's fantastic as heck

I can imagine! I just took delivery of the BMCC MFT and I'm getting the same thing, battery, screen, blah blah blblah look forward to the C100 review!
 
Getting back on topic here... it seems there is a way around this "no aperture ring" problem. Adjust the aperture on a Nikon DSLR, take Lens off, mount it on the target non DSLR camera. Quite a hassle, and I don't know ANYONE who's used that method successfully, but apparently it can be done...

According to who? The aperture lever is spring mounted. As soon as it's removed, it will go back to fully closed. Far better idea is to "prop" the lever fully open and simply use ND to control your exposures. Or just buy lenses with aperture controls.
 
Just so we all understand, to the OP, are you trying to find a solution using your HPX170 + M3?

As this is posted in the AF100 section.
 
hes looking for a nikon to nikon mount aperture controller. the valid options have already been discussed earlier in the thread
