Lens Tests and Camera Reviews

Why?

As a Canon professional, you (and your camera) require 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 only available in Version 2.0, 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, 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.

Nikon G to Canon EF AdapterWe have joined the growing ranks of suppliers who have stopped selling AF-confirmation chips as standard. The bottom line is that the chips are just not made with a low enough failure or rejection rate to make them as hassle-proof as we'd like. The LiveView argument now also weighs: increasing numbers of demanding photographers are discovering that fully magnified LiveView focusing is equally convenient – and much more accurate – than old school red-box AF-confirmation. Having said that, If you wish, we can provide your adaptor with an AF-confirm chip for an extra £25, but we cannot guarantee 100% trouble-free operation on your camera – even though we will test it on a 5D II first! In the event of problems in this regard, we will exchange the adaptor once only.

When you order, please specify which camera you're using. Older generation Canon DSLRs have a mechanical spring switch inside the lens mount that enables electronic communication between EF lenses and the body. In order for the chip on the back of the adaptor to trigger 'red-box' autofocus confirmation, this microswitch must be set 'on' by a small pin mounted on the adaptor. If, for instance, you're using a Canon 1Ds Mark I, AF confirmation may not be provided by the chip alone. What you need is 'chip and pin'. However, if you intend to use the G adaptor on a more recent camera, the adaptor works more smoothly without it. Here's the official list:

Canon D30: pin required ('Early' model camera)
Canon D60: pin required ('Early' model camera)

Canon 1D Mark I: pin required('Early' model camera)
Canon 1D Mark II: pin required ('Early' model camera)
Canon 1D Mark III: no pin required ('Late' model camera)

Canon 5D: no pin required ('Late' model camera)
Canon 5D II: no pin required ('Late' model camera)

Canon 1Ds Mark I: pin required ('Early' model camera)
Canon 1Ds Mark II: pin required ('Early' model camera)
Canon 1Ds Mark III: no pin required ('Late' model camera)

For all other Canon DLSRs (including the 20D, 40D, 400D and 450D) no pin is needed. Please specify 'Early' or 'Late' model camera on the dropdown above . . . .

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?

Turnaround cannot accurately be predicted. However, in the past, it has taken as long as four 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. Otherwise, orders are shipped on a 'first-come, first-served' basis. Please note that by August 2009 we expect all suppy problems to be resolved, and we should be able to supply ex-stock and provide customers with inventory level information before they order.

Nikon G to Canon EF Adapter

Frequently Asked Questions:

Q. I’m nervous about removing the weatherproofing. Should I be?
A. 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.

Q. I keep getting Err99 with my chipped adaptor. What’s going on?
A. Each chipped adaptor is tested individually on at least one Canon body before shipping. Occasionally we receive reports that a particular body errors with a given adaptor (actually, the adaptor is innocent; it’s the AF confirm chip’s fault). Usually, when returned, they work fine with our Canons. Often, firmly rubbing the contacts with a clean cloth is enough to restore normal function. Welcome to the wacky world of the stuck-on AF chip! Unfortunately, it is not possible at the present time to source third party chips that match the reliability of Canon’s own, which is why many suppliers have stopped selling them. Because LiveView removes much of the necessity of AF confirmation, I would recommend removing the chip if you have problems. However, if you rely heavily on red-box confirmation (not in any case a wise policy with a 14-24mm), we will swap your adaptor for another. If that doesn’t work, the only solution is to do without AF confirmation.

Q. 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?
A. 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.
