Notices before purchasing:
- Canon STM series lenses don't work with our Canon EOS (EF / EF-S) D/SLR Lens adapters.

Quality build. Works great with most of my Canon lenses, except the nifty fifty, which only works in a quasi-lens whacking mode. Something about the alignment on the lens doesn't permit the focus ring to have an effect when attached to my G7. I've seen other reviews that say it works with their 50mm, others say it doesn't; I'm one of the unlucky ones. Still, well worth the price - it's quick to attach, solid, and feels like it will last a long time.EDIT 3/31/18: After toying around a bit, I've found a way to get this to work with my Canon 50mm. It involves attaching the lens to my T3i, obtaining focus, and then reattaching the lens to my G7. Sometimes the focus ring works, sometimes not, but after attaching the 50mm it will be in focus, though only at the exact focal distance (100mm for me due to 2x crop factor). I like this product enough that I ordered a few older Canon EF lenses, so I'm still a happy customer.

I got this adapter to use some semi-functional EF-mount lenses with my OM-D E-M5. I wasn't​ expecting​ this good an adapter for the price. Feels very solid, infinity is preserved and focus scales seem to still be accurate. Of course you don't get autofocus, but manual focus works perfectly well in most scenarios. In addition, there's no way to change the aperture with this adapter directly. Instead, you either have to use lenses wide open (which makes manual focusing a bit difficult) or attach a lens to an EOS camera, hold down your DoF preview button, and then take it off and put it on the adapter. This is a bit of a tricky process and certainly not suited to fast-paced professional shoots, but for landscapes or studio photography where nothing's moving very fast it's a great, inexpensive way to use nice lenses with alternate systems.

I bought this to use some of my Canon and 3rd party EF lenses on an Olympus E-M1 Mark II camera. As I have most general lenses for the E-M1 I really only needed it for 2 of the EF lenses, one a Tamron 150-600 and the other a Canon 100mm Macro. Both worked properly with this adapter and I was able to get good sharp and very usable photos with it. However there are some restrictions with this adapter that should be mentioned.One, this is a "dumb" adapter in that it has no electronic components and thus there is no communications between the lens and the camera. That means that auto-focus, aperture adjustment and lens stabilization will NOT work. If you need those you need to look for some of the more expensive converters that contain electrical connections.Two, your camera will not know a lens is attached so you need to make sure you can shoot "without a lens".Third, since your lens becomes a strictly manual lens you can not adjust the aperture from the camera and you will either end up shooting wide open or you will have to set the aperture of your lens with the native camera for the lens and then find a way to dismount the lens without resetting the aperture. I do this with the DOF button on my Canon.Lastly, you have to be prepared to focus manually. If your camera provides "focus peaking" you might want to use that to get your shots in proper focus.If you are prepared to use your camera with the above restrictions this is a great little adapter and I have been able to use my EF lenses to good advantage and been very please with the results. The adapter seems solid and well made, but comes without any case or end caps to keep it clean and undamaged. Mine came in a plastic bag and I now store it, in my camera bag, in that plastic bag or leave it attached to one of my EF lenses in the lens case. Since this adapter fits an EF lens on one side and a M4/3 camera on the other you probably can also buy an Olympus lens end cap and the Canon camera body cap. That is what I plan to do to keep this clean.

I bought this lens adapter to use my old Canon EF lenses on my LUMIX DMC-G7 camera. It fit the camera perfect and the EF lens also fit perfect. Nice and snug and absolutely no play. This is just an adapter and no electronics, so the lens just becomes manual focus which I knew that before purchasing. So it’s perfect for what I’m using it for. The camera will give a warning message that no lens is attached. I just had to change a setting on the camera to allow it to shoot without a lens. Now I have a good variety of older Canon lenses to use. I recommend this adapter!

This adapter is dumb, meaning it does not enable the electronics inside the Canon lens. I use this adapter to attach my old Canon lens to my Olympus camera. It works well in that regard and is a very solid piece of camera equipment. With the price being what it is, it's worth it if all you want to do is attach a lens. However, it lacks the ability to auto focus, which causes a problem especially with my prime lens. So this adapter, being a good price and designated functionality, is not actually that useful in my opinion. A smart adapter is about $200 more though so decide if this is what you want.

Great value for someone with a M43 and a EOS camera. As expected you must use manual focus and you cannot change amputure. Image is a little softer than when using it on a true EOS camera. I included a shot taken with a canon EF 75-300 1:4-5.5 III USM on the Panasonic lumix dmc-g7 mirrorless camera. No complaints about this adapter does everything as expected. Great if you want to use some cheaper used lenses. M43 lenses are pricey and some vintage lenses can come cheap, perfect temp solution while saving for a high end lens. Now my wife and I can share EOS lenses.

HabÃa leÃdo alguna crÃtica negativa y me hizo dudar. Tiene aspecto de buena calidad y funciona perfectamente. No he tenido problemas para ponerlo ni quitarlo. Va suave y parece quedar bien sujeto tanto en la cámara como en el objetivo. El enfoque está claro que tiene que hacerse de forma manual. He usado el focus peaking y no he tenido problemas al enfocar. No he notado pérdida de calidad óptica, puesto que no tiene lentes. La cámara no te permite modificar el diafragma, pero lo puedes hacer manualmente antes de montarlo. La medición de la exposición, no es del todo correcta, puesto que al no haber comunicación, la cámara desconoce el f que se está usando. Todos estos pequeños problemas, son lógicos al no haber comunicación y ya me los esperaba. Por tanto estoy contento con el producto y por ahora cumple con lo prometido.

Testato con successo su diverse camere M43: Panasonic GH5 & G9, Olympus E-M1 MKII, BMPCC 4K con diverse ottiche EOS e combinazioni più "esotiche" e adattatori intermedi. (foto: adattatore per LOMO OCT-18 -> EOS->M43)Baionetta solida e fluida in entrambi i "mount" nessun problema con le distanze minime e massime di messa a fuoco.Ovviamente è per ottiche manuali e non c'è nessun tipo di contatto per autofocus o altro

Ich bin überrascht und begeistert. Ich habe heute den K&F Adapter erhalten. Dieser ist vollständig aus Aluminium gefertigt, was bei diesem Preis echt klasse ist. Dies steht zwar in der Beschreibung drin, glauben konnte ich es aber nicht.Die Passgenauigkeit ist hervorragend, mein EF-s Objektiv aufgesetzt, dies rastet satt und ohne Kratzen ein. Dann die Kobination auf meine GX7 aufgesetzt, ebenfalls mit optimalem Widerstand und sauberes Einrasten.Der Rest ist bekannt. Da keine elektronische Verbindung vom Objektiv zur Kamera besteht, wird idealerweise an der Kamera das Av Programm gewählt, somit stellt die Kamera noch die Verschlusszeit und ISO-Wert automatisch ein und das Bild wird optimal belichtet. Aufgrund der fehlenden Blendensteuerung steht das Objektiv dauernd auf offener Blende. Mit der GX7 ist das aber kein Thema, da diese als kürzeste Verschlusszeit 1/8000s hat und so selbst bei hellem Tageslicht noch korrekt belichtet wird. Die Schärfe kann manuell scharf gestellt werden, wie gewohnt bei manueller Steuerung der Schärfe.Alles in allem spart man sich bei Brennweiten, die man wenig nutzt, einen Kauf im neuen Anschlusssystem, in meinem Fall ein Weitwinkelobjektiv. Einzig der Faktor ist im MFT-Format 2,0x, bei APS-C 1,6. So hat man noch 20mm (KB) statt 16mm (KB), wofür der Adapter aber nichts dafür kann ;-)

Se trata de un adaptador puro y duro. Un trozo de metal que hace de enlace entre una montura (Olympus micro 4/3) y un objetivo (Canon EOS), pienso que lo poco que puedes pedirle es que encaje bien y que sea robusto y estas cualidades las tiene. Siempre ten en cuenta que no vas a poder usar el AF ni controlar el diafragma del objetivo ya que no hay ninguna comunicación entre la cámara y el objetivo. En el caso de mi olympus como tiene focus peaking aproxima el enfoque, pero vamos, tampoco es la panacea.

Arrivato in tempi rapidissimi, costruzione buona, si adatta benissimo alla mia olympus m10 mkII e ai miei obiettivi EF-S e EF. Naturalmente non ci sono controlli elettronici ed il è fuoco manuale, ovvio. Non ho capito invece se il diaframma è sempre quello più aperto. In ogni caso un ottimo prodotto per il suo prezzo, posso usare il mio Lens Baby (che ha diaframmi meccanici) esattamente come sulla reflex
