You might check a manufacture Fotodiox - they make a ton of adapters. Ebay is the other site.

NSXType-R,
Yes thanks for the suggestion. That would work for a Pentax K mount but I am looking to adapt a Pentax 110 format lens. This was a miniature SLR using 110 film. See http://en.m.wikipedia.org/wiki/Pentax_Auto_110. I bought some lenses on eBay and I think they should cover the Nikon 1" sensor, but nobody seems to make a mechanical adapter.

I guess if you can find a Pentax to F mount adapter, and then stick that on the F mount to CX mount adapter, it might work. I'm not sure how smart it is to have 2 adapters working at the same time though.

Adapterception!

Hi,
Has anyone ever found an adapter to put Pentax 110 system lenses on a Nikon 1 camera? I've searched the forums, Google, eBay, etc for several months but come up with nothing. I found plenty of Pentax 110 to m4/3 and Sony NEX adapters but nothing for the Nikon 1 mount. Is there some physical incompatibility? Forgive me if this has already been addressed but I've searched with due diligence and couldn't find anything.
Cheers,
Telecentricity

Oh ok well thanks for the help any ways.

Novoflex has one once. Those are usually $200+. Unless you wanted macro, I think a adapter would have to have a glass piece added to get to infinity. Probably not worth it.

I don't think there is one.

Hey,

I have come across a great deal on an old Canon ae-1 with some lenses, would anyone have an idea where i could get and adapter so it would work on my Nikon D90, any help is greatly appreciated.

By the way, my power pack is as follows
- Car battery
- 110V inverter
- EH-6

Not very efficient, nor portable, but lasts for ever.

Lol, that brings new meaning to the term "Drive through shooting"!

dormant, re your power pack - I'd find it hard to get it past security at events, but I like your style ;)

I guess a diesel generator as backup would make some impact too

Hey dormant - I realised what you were getting at after I pushed "post" ;) - sorry was on a do 10 things at once at full speed kind of day ;0
So, yes in theory it should work, still waiting to hear from Quantum...

Cheers

My (badly-made) point was that it looks as if the EP-6 has the same power connector as D3s etc, so existing Quantum cable would work.

Yeah, but the point is that by using the Quantum you are not tied to a wall socket - its a battery pack. EH-6[b]+EP-6 doesn't give you that. On other websites there are discussions about the possibility of third party battery manufacturers supplying high-capacity batteries for the D4 (which of course could not be sold in Japan). The advantage over the Quantum is that they would be internal.

Nikon's own website says that the old EH-6 power supply is compatible with the D4: http://www.nikonusa.com/Nikon-Products/Product-Archive/Power-Adapters/25282/EH-6-AC-Adapter.html#tab-ProductDetail-ProductTabs-CompatibleWith

Maybe that needs the EP-6 as well.

Update
======

There's a photo of the EP-6 on Nikon UK's website: http://www.europe-nikon.com/en_GB/product/accessories/slr/slr-power/ac-adaptors/ac-power-connector-ep-6

I suspect the hidden end of it has the standard Nikon socket for the EH-6 or EH-6b.

I had a convo today with Quantum Instruments about using one of their Turbo batteries to power a D4.

Might be a workaround for the reduced capacity of the new D4 battery (introduced I understand because of new regulations in Japan) compared to the D3/D3s, which some of us have got used to and may still need in some circumstances.

However Quantum are still waiting to get their hands on a D4 so cannot recommend anything yet.

I see that the D4 does not have an external DC-in plug which the D3s/D3/D3x have.
Nikon's own external supply for the D4 consists of a new EP-6 power connector which fits into the battery chamber, and EH-6b AC adapter which plugs into EP-6 one end and the wall supply the other. Hopefully Quantum can work with the EP-6...

I have the Nikon,50mm F1.8. I have used it on the F2 bellows previously. I only want to experiment with the extension tubes,especially as a friend offered them as a thank you for a favour I did for him. I have a Nikkor,105mm,F2.8, micro I have just acquired before Xmas so have been getting to know it over the holiday season. I will perhaps try and buy the PN-11 in the future, but they seem expensive on the auction sites.

Hey guys ..I have solved the problem ! Its an F mount male adapter I need for the extension tubes. How did I find out ? ...Well we searched through my friends camera bags and found it, he had forgotten about removing the male adapter some time ago.
Thanks to everyone for your enthusiastic replies. I am new to posting in forums and am thoroughly enjoying it, but do I feel a twinge of NAS coming on ?!!!!

Do you have an older style lens to use with your extension tubes, I use mine with a 50mm F1.8
Your lens should have manual aperture control to work with most extension tubes, unless the extension tubes is a more modern style with electronic connection to the lens

Pete

I missed "lens onto the tubes" part so I presumed it was "tube to the body".
And yes in the case of 57mm body mount it is more likely some video camera to F-mount lens adapter and it is probably for focusing and not for macro, so you was right after all.

If it is a 57mm then you can eliminate M42 and Pentax screw mount. They're both 42mm.

I still think its a bellows for the the old pentax screw mount aka M42 ..
http://en.wikipedia.org/wiki/M42_lens_mount

something like this one? http://www.trademe.co.nz/Electronics-photography/Camera-accessories/Other/auction-260004554.htm

the adapter? http://www.rugift.com/photocameras/nikon_lens_adapter_with_lens.htm

But if it will mount an f-mount lens on the side machined into an f-mount shape, it won't mount to the body. Isn't that right? I think astrophotographer's right—it's some adaptor to let you connect an f-mount lens to a CCD camera that has a screw mount.

If you have an outside thread on the other side of the ring what you have is an reversal adapter ring.
It is used to mount the lens in reverse position for better macro IQ by screwing the lens filter thread on it.
If it is really 57mm you could try and get 52mm step up adapter to be able to mount 18mm-55mm or 50mm for example but I doubt you will find something like this because 57mm is non standard size. 58mm and 55mm are standard filter thread sizes so you better check you measurement.
One more thing, even if you manage to find an 52mm step-up adapter 18-55 or any other G type lens will be useless because you will not be able to set up aperture.
