Viltrox EF-M1 Auto Focus Lens Mount Adapter with Aperture Control, EXIF Transmitting for Canon EOS EF/EF-S Lens to M4/3 Olympus Panasonic Camera GH4 GH5 GF6 GX7 E-M5 E-M10II E-PL5

I have a Olympus OMD EM10 III and also an old 35mm Canon camera. I forked out a substantial amount on lenses in the 2002 just to be overtaken by the digital revolution on cameras. Now finally I bought a lens adaptor to try and use my Canon lenses. It was important for me to be able to have auto focus and that the camera works with the lens without any major issues. It works for my EF 28-135mm just fine and even the EF 28-105 works despite not being on the list of supported lenses. I ran some test for clarity and as an amateur I can not spot any lens issues on the pictures. Yes auto-focus is sometimes a bit slow but again I did not expect the same performance as with Olympus lenses. I am very happy with the product and I can reuse my old lenses. TBH those big lenses are heavy and for a "day out" I'd probably use the original Olympus lenses so I don't have to carry the weight. For a bit more experimental picture taking I certainly would use the big Canon lenses. Best of both worlds really. Anyway the adaptor worked out of the box with my combination of camera and lenses and even though there is a firmware update available I did not install it on the grounds the "if it works why fix it" A bit on the expensive side but I don't regret my purchase.

I'm using this to adapt Canon "L" glass to the Fujifilm X-H2. When I initially received the adapter I put the latest firmware on. However, when I started using the adapter with my lenses and the X-H2, is was a total disaster: the autofocus on all lenses just "hunted" and I frequently got a green focus lock indication, when the lens was blatantly out-of-focus; I had to switch to manual focus mode and use focus "peaking" to get anything in focus. Not a good start. However, a little research on't web indicated that things started to go t*ts up with this adapter at firmware V2.28 and that V2.26 was more stable. So, with little to lose (as I would have returned the adapter had things not improved) I downgraded the firmware to V2.26; and et voila everything worked on all my lenses. And the most amazing thing is that it worked just as well with video as stills; I was using a Sony A7 iii with an adapter and although stills were ok with auto focus video was a disaster. So, YMMV but whatever lenses and body combination you have, if you get this adapter, and things don't work properly, try V2.26 of the firmware before you send it back. I'm giving it four stars because all my L glass works as if it were native (or very near if not) and loses the extra star due to the hassle of having to research firmware that would enable correct functionality with my equipment. The image shows Rayman (looking a little dusty these days) shot with EF 24-70 f/2.8 USM L (MK1) and the Fujifilm X-H2 with this adapter.

I shoot primarily full frame on my Canon 5D Mark IV for my commercial photography, but carrying that around for street photography is just not very feasible. I wanted a small, full-frame, easy to use, quick to deploy camera. The obvious answer was the Lieca Q2, but I don't have that kind of cash to throw around so my next option was to buy an M6 Mark II, put this adapter on the front and use all of my full frame lenses at nearly no crop (well, 1.1 times crop, so nearly nothing) with the added bonus that it adds an extra stop of light, so a 24mm F2.8 becomes a 26.4mm F2 lens. Absolutely the perfect combination, now I can carry this camera around and use it with any of my full frame lenses, gaining a stop of light too! In the picture you can see it with a massive 24-35 F2 from Sigma. This lens is effectively a 26.4 to 38.5 F1.4 lens now and although it is very front heavy, it works really well. The adapter also has a tripod mount, you can balance these bigger lenses a bit better and relieve some of the stress on the camera mount when on a tripod. You can update the firmware of the adapter to the latest version which seems to have resolve some old issue where it would drain the battery of the camera even with the camera off, I've not had that issue at all. Lastly, image quality. I've not seen any real detriment to image quality with the addition of this adapter, the optics on it seem high quality enough. I do have the original Canon adapter (not a speedbooster) and pixel peeping didn't show any significant quality difference from a non-optic adapter to this one. The second picture (the one of the Omega watch) was shot using the M6 Mark II and this adapter with a Sigma 105mm F2.8 Macro Lens. You can be the judge on whether it resolves good quality or not :) It might seem a little expensive but in photography terms this is cheap, especially if you already have a line of full frame lenses (particularly primes you are used to shooting)

Great full frame “like” speedbooster, used specifically for professional looking video conferencing paired with an canon m50 mk2 and Ef 50mm stm lens. Have tried it out for some photography as a checker and has produced exactly what you would expect with the extra stop of light it adds to your lens, and hasn’t slowed or altered the auto focus at all. If your starting out in photography and don’t have the budget for a full frame body, this is a fantastic start point. Or if like me your job has become entirely working from home, then this is a stunning conference camera setup that gives a very professional feel to your calls.

I had purchased the speed booster for my gh5 and although it fits quite well onto the camera, IT DOES NOT WORK with the lens. The Lense is completely loose and upon further research, this is a very common issue

When i received it i was blow away by how much wide it makes my sigme 18-35 then realized it wouldn't focus to infinity. After some research its a fairly simple fix but isnt completely fixed with other lenses. Also one of my old cheaper canon lenses wont work on the adapter so i can change the aperture of the lens which is annoying.

Exactly what I needed for my GH5 and Canon-fit lenses.

Utilizzo su fuji xh2-s principalmente con ottiche manuali. Non ho notato difetti. Ho provato anche qualche 'vecchia' lente EF, mai avuto problemi o sganci con autofocus o regolazione del diaframma.

Hallo Habe meinem Mann diesen Adapter geschenkt. Er braucht ihn, um an seiner Lumix G81 die vorhandenen Objektive mit Canon EF/EFs anzuschließen. Die Lumix wird größtenteils für das Focusbracketing/Stacking mit dem Elektronischen Verschluss und dem Canon Macro-Objektiv verwendet. Die Firmware des Adapters wurde zuerst auf die Version 3.3 von der Viltrox Website aktualisiert. Die Firmware der Lumix G81 ist die 1.4. Im Kamera-Menü wird nach adaptieren der Objektive die Firmware der Kamera UND des Adapters angezeigt !! Als Test wurden trotzdem folgende Objektive mit dem Viltrox - Adapter an die Lumix G81 adaptiert : Canon EFs 60mm Macro Canon EF 70-200mm L 4/IS Canon EF 50mm IS/STM Canon 16-35 L 4/IS Tamron 90mm 2,8/ IS VCC F004 Tamron 24-70mm 2,8/VC A007 Irix 11mm 4 alle Objektive haben an der Lumix G81 funktioniert. Das IRIX 11mm natürlich nur mit manuellem Focus. Bei allen Objektiven springt der Kamarainterne Bildstabilisator an und funktioniert !! Besonders begeistert ist mein Mann, dass das Tamron 90mm funktioniert !! Der Adapter erfüllt also voll und ganz unsere Erwartungen. Die Verarbeitung ist einwandfrei, da klappert nichts und die spielfreie Objektiv-Adapter Kombi sitzt spielfrei an der Kamera. Ich habe 95 Euro bezahlt, woanders könnte ich fast das doppelte für einen anderen Adapter ausgeben, ob der in Funktion oder Verarbeitung besser ist, weiss ich nicht. Ein Vergleich im Netz wäre ganz interessant. Eine Bedienungsanleitung in Deutsch mit Erklärung des Firmware updates wäre schön. Wir können bei unserem Test natürlich nur von der eigenen Kombi ausgehen und nicht auf Gehäuse und Objektive anderer Nutzer zurückgreifen.

J'ai beaucoup hésité avant d'acheter le viltrox vu les différentes mauvaises expériences mais avec la nouvelle mise à jour je peux vous assurer que le viltrox fonctionne à merveille et même avec mon sigma 50mm 1.4 qui n'est pas repris dans la liste des objectif compatible, le AF va parfaitement, si vous ne faites cependant pas la mise a jour du firmware du viltrox vous aurez qlq soucis mais bon ça prend même pas 5 minutes pour faire la mise à jour.

Funktioniert und ist fast schon ein Schnäppchen! Ein Canon EF 85 f1.8 wird zu einem f1.4 - und wenn man am Adapter den inneren Ring solange dreht bis das Objektiv im unendlichen fokussieren kann, dann ist es super scharf. Mit einem Nikon zu Canon Adapter kann man dann auch Nikkor objektive mit manueller Blende verwenden. In meinem Fall fährt ein altes 15mm f3.5 über das fuji10-24mm drüber, weil es mit dem Adapter nicht an Schärfe verliert und nicht verzerrt. Guter Kauf!

Il Viltrox EF-EOS M2 da nuova vita alle ottiche canon EF. La resa è veramente buona. Lo ho provato con successo con vari obiettivi fissi e zoom ed il funzionamento è stato corretto. La costruzione è robusta e nel mio caso su Canon M6 senza alcun gioco.
