Lens Tests and Camera Reviews

Why?

As a Canon professional, you (and your camera) need the best lens for the job. Sometimes that's a Canon L; sometimes it's a Leica, Olympus or Zeiss – and sometimes it's a Nikon. Adaptors of varying quality are commonly available for many systems, but state of the art Nikkor lenses released under the 'G' designation (without an aperture ring) have previously been off-limits to Canon bodies.

Nikon G to Canon EF AdapterOur adaptor is currently the only solution that provides aperture actuation for Nikon G lenses, as well as mounting compatibility – enabling Canon users to mount and manually control peerless lenses like the Nikon 14-24mm f2.8 which has repeatedly been proven as the highest resolution ultrawide lens you can use on a 5D II or 1Ds series camera.

What?

Once the V2 adaptor is attached to a Nikon lens, it can be mounted onto a Canon body just like a Canon lens. If an AF-confirmation chip is fitted, your Canon digital camera will even focus-confirm just like a Canon lens. But uniquely our adaptor replaces the 'lost' aperture ring of G Series lenses, enabling video or stills shooters to set any aperture manually, even when the lens is mounted on a Canon DLSR or Canon-mount video camera. Infinity focus is also guaranteed. Please note that VR, auto-focus and auto-aperture functions are not available when the lens is adapted in this way.

Nikon G to Canon EF AdapterEach adaptor is individually checked and optimised for the 5D II + 14-24mm G lens, but it works equally well on all Canon full frame, 1.6x or 1.3x sensor bodies, enabling EF-mount owners to use the 10.5mm Fisheye, 105 Macro, 200-400mm or any other aperture-less G series lens. This adaptor was used in all the 1Ds III and 5D tests of the 14-24G lens on this site.

Which? PLEASE READ CAREFULLY!

The adaptor is now in Version 2.1, a slight modification of that previously known as 'Lever-Operated', and now based entirely on the world's finest Nikon-Canon adaptors made by Rayqual.

The original design (previously known as the 'Rotating' adaptor) has officially been discontinued, If you have a special requirement for the older version that will function with the Nikon lens' weathersealing gasket intact, please email . . however, the new version is better designed, more robust, harder to make, nicer to use, works with all Nikon G Series lenses, and locks the lens and adaptor into fixed positions. The diaphragm is actuated via a control ring sandwiched inside the adaptor. Please note that the V2 adaptor requires the removal of the gasket on the rear of the Nikon G Series lens. This operation takes about a second and is reversible, but fiddly. Some customers have reported that their Nikon service centre has reinstalled the gasket without charge.

Nikon G to Canon EF AdapterIt's important to note that third-party AF-confirmation chips are not as reliable as Canon's own. The latest programmable chips installed on the V2.1 (an additional £30) are the best available in our experience, and usefully identify the lens in EXIF data. However, we cannot guarantee perfectly glitch-free operation on your body – even though each adaptor and chip is tested on a full-frame Canon DSLR before shipment. The LiveView argument also weighs: demanding photographers know that 100% LiveView focusing is by far the most accurate means of checking focus with a lens as wide as 14mm.

Please also note that owners of Generation II Canon DSLRs (ie, 1D Mark II, 1Ds Mark II) require an extra adaptor modification if ordering the chipped version of the V2. These cameras have a mechanical spring switch inside the lens mount that enables electronic communication between EF lenses and the body. The adaptor musy be modified to trigger this microswitch and allow the camera and lens to talk.

How?

The V2 Nikon G Adaptor enables all apertures to be selected without detents via a stepless 10mm range of movement. Legends on the adaptor indicate f2.8 / f8 / f22,.

When?

In the past, it has taken as long as five months to deliver adaptors to customers who placed orders at non-optimal points in the production cycle, Parts are sourced from Japan, America and China, creating random customs and import delays. Hand-assembly and machining in the UK is performed on a small scale which compounds scheduling problems, Because lead times are subject to unpredictable delays please contact us before placing an order if you have a specific deadline. We may be able to accommodate you with a loan unit in the meantime.

Please note that we are working towards a new, more efficient production pathway that will ensure reliable on-hand stocks for immediate delivery via both the website and a new dealer network. Watch this space . . . .

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. Do store the removed gasket in a safe place in case you need to sell the lens in the future, and don’t want it to appear ‘Canonised’. The gasket will press back in with the aid of a thin-edged tool.

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. Sort of. Manual aperture Nikon lenses have a short and long tab protruding from the body-side of the aperture ring that foul on the aperture actuator ring built into the adaptor. If you want to swap Nikon lenses between Nikon and Canon bodies, file down these plastic tabs by about 2mm, carefully shielding the lens mechanisms from scurf. Please note that this will impair metering accuracy when the Nikon lens is used on a Nikon body in manual aperture mode, though conventional auto/electronic aperture function is unaffected. Nikon users typically set manual-aperture lenses to the smallest aperture and deploy electronic aperture control from the body for greater accuracy and convenience. However, the design goal of this adaptor was to replace the function of the aperture ring missing from G series lenses. If you simply need to adapt an older Nikon lens to a Canon body, simpler Nikon F > Canon EF adaptors are widely available, much cheaper, and will do the job just as well.
