Version 3.0

Lens Tests and Camera Reviews

Now produced in collaboration with Novoflex


Canon users can access the widest range of lenses for specific tasks: Canon, Leica, Olympus, Zeiss – even Nikon – glass can easily be adapted. Unfortunately most of the best (and all the new) Nikkor lenses are designated 'G' and have no aperture ring, Lenses like the Nikon 14-24mm f2.8 G have therefore previously been practically unavailable to Canon professionals, despite being greatly superior optically.

This adaptor allows you to mount any Nikon G lens on any Canon body, and it reclaims the functionality of the 'missing' aperture ring. Manual iris operation is particularly suited to the needs of videographers. All the current and future Nikkors* (including the 24mm f1.4 and 16-35mm f4) can now be used on Canon 5D, 1Ds, or 1 series cameras with full manual control – any aperture can be preset and held by mechanisms within the adaptor.

Operation

Once the V3 adaptor is attached to a Nikon lens, it can be mounted on a Canon body just like a Canon lens. The adaptor can be swapped in seconds between different Nikon F or G lenses. The optional comms chip allows through-the-lens focus confirmation (red or black square and beep) just like a Canon lens. This chip is programmable: allowing you to manually EXIF-encode a focal length and aperture value in each capture for image identification in post-production.

All possible apertures can be selected steplessly using the blue control lever: there are no detents limiting operation to f2.8 / f4 / f5.6, etc. The selected aperture is friction-fixed until manually repositioned.

Infinity focus is perfectly achieved. We strongly recommend the use of LiveView as a focusing aid with this adaptor.

VR, auto-focus and auto-aperture functions are not retained: operation of the lens is entirely manual, similar to large format lenses: a scene is typically composed and focused with the aperture wide open, then manually stopped down to expose. Canon cameras meter through the lens; full automatic metering is continuously available.

The adaptor does not feature a weather-sealing gasket like the latest Nikon G lenses: therefore its environmental resistance is slightly less than when used with a Nikon body. Please note that It is necessary to remove a small part of the gasket to mount the adaptor.

Testimonials

The 16:9 Nikon G adaptor has been used to shoot advertising for Maserati, weddings for celebrities, wildlife for the BBC Nature Unit, video for Red, and tests inside R&D HQ at Nikon Japan. Our customer list includes some of the world's most highly regarded photographers on every continent who have used the adaptor, literally, from pole to pole.

History

We released the world's first commercially available Nikon G to Canon adaptor on Christmas Day, 2007. Version 1 was our modification of a Nikon F Pro adaptor made for Fotodiox. With the locking mechanism removed, the adapted lens rotated securely under the mounting blades, constrained to a 10mm range of movement by modifications made to the adaptor's side wall. This provided just enough movement for our stop-down lever to actuate the iris. It worked: we shot the first ever Nikon 14-24mm images with Canon bodies with the V1 Rotating Adaptor, and hundreds of units remain in active duty.

However, parts supply problems and a desire to improve the quality and durability of the adaptor led us to Rayqual in Japan, who make outstandingly engineered camera equipment. Using their higher quality adaptors as a base for our modifications enabled us to launch the V2 adaptor which featured a number of unique CNC machined components that were hand-finished and painstakingly assembled by a single, highly-qualified technician in England. The V2 was more complicated, much more robust and far nicer to use, but also more expensive and again bedevilled by supply problems involving manufacturers in three (sometimes four) different counttries, and time-consuming local production. We couldn't make them fast enough to keep pace with demand, and waiting times were long.

So we approached Novoflex in Germany (who we believe make the world's finest adaptors) with a view to manufacturing the V2 entirely bespoke, from the ground up, and so the V3 was born. Version 3 is everything we wanted from the adaptor in the beginning: not least: no more supply problems, no more time consuming modifications, no more waiting lists. And we were able to improve machining quality still further, provide a more easily understood scale for aperture control, seamless backward compatibility with Nikon F lenses, and minimise needed lens modification.

Economies of scale mean that we are now able to offer a better adaptor, always in stock, without a price increase. The un-chipped 16:9/Novoflex V3 Nikon G adaptor is also available worldwide from bricks-and-mortar Novoflex distributors, or direct from us online.

We exclusively offer the AF-confirm modification for orders placed through this web page at an additional cost of £25.

DELIVERY AND RETURNS: Delivery costs are calculated according to location, but range from £4-10. For emergency requirements, FedEx Global priority usually gets an adaptor to you anywhere on earth within 24 hours.

If for any reason you are unhappy with the adaptor within seven days, notify us immediately and we will process a full refund on safe return of your order, minus outbound shipping, any time up to 28 days after receipt of funds. If your order lands between production runs, we can usually arrange for you to receive a loan adaptor while yours is in production.

Nikon G to Canon EF Adapter

Frequently Asked Questions:

Will metering work?
Yes. When the camera is set to Aperture Priority (A-mode) correct exposure is automatically calculated through the lens.

Will auto-focus work?
No. Auto-focusing a Nikon lens on a Canon body would require complete conversion of the lens.

Will autofocus confirmation work?
Yes: if the adaptor is ordered with the optional chip. The electronic communication this provides betweent he lens and body also permits data about the lens to be programmed into EXIF data. Please see the instruction PDF for full details.

Will Vibration Reduction (VR) work?
No: again, the current version of the adaptor doesn't provide power to the Nikon lens. In principle, this functionality could be added to a future version.

Is the adaptor suitable for video application: I'm using my 7D / 5D II to shoot moving images?
Absolutely: a number of high profile video campaigns have been shot using this adaptor. We've noticed an increasing number of orders coming from videographers over the last few months.

Can I use your adaptor with the Nikon 10.5mm Fisheye? What about the new Canon 7D
Yes, and yes. We've not come across a G lens that isn't compatible.

What about the 24mm PC-E?
Sorry, not at this time. But never say never . . .

Can you only select f2.8, f8 and f22 with your adaptor? I only see three indicators . . .
All apertures can be selected: there are no detents on the aperture actuator: the indicators are only to provide an approximate indication of the aperture selected.

Aaah! The adaptor is stuck on the lens!!
No it isn't: there's a small, black release button recessed into the rear of the mount. Press it . . .

I’m nervous about removing the weatherproofing. Should I be?
No adapted lens retains its weather sealing. If you shoot in harsh environments, or are unusually reckless, you may be better with a nicely sealed Canon L lens instead of an ‘alternative’. In reality, much like a cycling helmet, the weathersealing will not save you in a severe accident. If you remove the gasket, store it in a safe place in case you need to sell the lens in the future,; it will press back in with the aid of a thin-edged tool. However, the new V3 adaptor only requires the removal of a small part of the gasket, retaining most of the original environmental protection.

Can I use this adaptor with manual-aperture Nikon F mount lenses like the AF 85mm f1.4? And what about Nikon-mount third party lenses?
Yes: the new V3.0 is completely 'plug and play' when swapping between Nikon F and G mount lenses.

I can't get it off my lens! Help?
Yes you can: the locking pin release button is located on the camera-side of the adaptor, next to the blue stop-down lever. Press it . . .

I need faster/more reliable international shipping: any chance of a next day priority shipment to the USA?
No problem. The standard shipping price quoted is based on Royal Mail's global Small Packet service, which almost always arrives without incurring additional duty costs, and rarely spends unwanted time in customs. However it is not a fully tracked service and typically takes 3-5 working days within the EU, and 6-10 working days elsewhere. The cost of upgrading to the tracked (and 1-2 days quicker) Airsure is an additional £5.95. Next-day delivery to most US (and many global) locations is handled by FedEx Worldwide Priority at an additional cost of £38.
