As noted by the other reviewers, the aperture of the EF lens in use cannot be changed when the lens is mounted on the micro 4/3 camera body, you also lose autofocus capability and the image stabilization function of the EF lenses. Those are the downsides to this adapter. The upside is the ability to use a wide range of Canon EF lenses on you Olympus or Panasonic micro 4/3 bodies. The best benefit here is the use of the long lenses and EF tele-zooms. You get an effective doubling of the focal length with no loss of lens speed. My 70-200/2.8 EF lens is now the equivalent of a 140-400mm zoom with the same maximum aperture of f/2.8 when used on my Lumix G1. In addition, the minimum focus distance of the lens remains the same. Not a bad compromise, in my opinion. Of course, you have to be aware that this doubling of focal length effect also doubles the likelihood of camera shake when handholding. Consider a tripod or use a higher ISO.

I've only used this adapter a short time so I can't judge long-term function, however, it seems to work well with the EF lenses I've tried on it: 50/1.4, 85/1.8, 70/200/2.8, 400/5.6 and 100-300/4.5-5.6. I've not tried the trick of stopping down the lenses on an EOS body and using it at an aperture other than maximum. That seems a little too involved to me although I can see how it would be a benefit under some circumstances--high speed lens in full sunlight, for example. Since I've not used it a lot and don't know how well it will hold up long-term, I'll only give it 4 stars.

If for no other reason than to experiment and have some fun, I would recommend this adapter.

Do you have multiple Canon EF Lenses? How could you NOT buy this product? You paid too much NOT to be able to use them on your Micro 4/3rds body. Not to mention that other than the 20 f1.7 pancake, there really aren't many fast lenses available for micro 4/3. Now I can use my 50 f1.4, 100 f2.0, 135L f2.0, & 24-70L f2.8

Yes, yes...no Aperture control using the 4/3 body - you must set it to a certain F stop on your Canon Body and (while holding the 'depth of field preview' button) remove the lens.

(I shoot wide open most of the time anyway)

And, I'm sure you know, there will be no Auto Focus. That does suck, but it's to be expected.


In short, it's a want in my case not a need...but it sure is fun to be able to mix my current lens collection with my new GF1.

Build quality is above average, but is nothing to write home about. It works as advertised.

It seems the bad reviews on this product are a result of people not knowing that it does not allow you to change aperture, or the reviewers didn't know how the single mechanism on the device works. Fotodiox really should have included a simple one-step instruction with the product: to remove the adapter from the lens, pull the tab TOWARD the camera and rotate the adapter. You don't push the tab in, up or down, as we're used to doing with tabs/buttons. You pull it toward you/the camera. The Kippon adapter works the same way, which is why I knew to do it on this one.

Beyond that confusion, the adapter is fantastic! I honestly expected a piece of junk for this price, and I only needed it to get through one shoot. I was happily surprised to find that it's a solid piece of gear and fits perfectly on both the camera and lens. The Kippon adapter has some play to it, but this one is totally solid without being too tight to remove - really a perfect fit. The finish on it even matches Canon lenses, making it seamless. I tested it, and it worked without issue on all my Canon lenses: 16-35L, 24-105L, 70-200L, 100 Macro L, 50mm, 85mm.

If you need an adapter that allows you to change aperture, get the Kippon adapter for $200+ - beware though that the aperture is within the adapter, it's not using the actual lens aperture, and most people report serious vignetting halfway through the aperture range. Or you can wait until later in April 2011 when the Birger adapter (MSRP $700) is released. The Birger adapter will allow you to use the lens aperture, plus the OIS and auto-focus. This Fotodiox adapter only fits the bill if you're OK with manual-only focus and you're in an environment where you know you won't need to change aperture. I.e. I used it with my Panasonic AF100 on a shoot where I knew I would be shooting wide open the whole time, and I could make small adjustments with the camera's ISO settings to handle lighting variations. I brought along my Canon camera so that, if needed, I could put the lens on the Canon, change the aperture, and then put it back on the AF100. There's no way I'll do that long-term though, I'm buying the Birger the minute it's released.

As another reviewer has already mentioned, if you know that you have to shoot wide open and use manual focus then this is a pretty awesome addition to your camera gear. It instantly allowed me to use all of my older canon lens from the film days. For convenience, I leave it on my 50mm macro lens and use an existing 4/3 rear lens cap to cover the back. And just like that I have an additional macro lens for my GH2. The construction is solid and it fits the camera very tightly. Just a reminder, you have to set your camera to "Shoot w/o lens" in order for it to work.

I recently bought Olympus PEN E-PL2. I have been using Canon DSLR and had several nice lenses for it. This adapter lets me use my nice Canon lenses on my new PEN for less than $30. It was only logical to get it. I tried Canon EF 16-35L, 24-105L and 70-300. They all work great on E-PL2 through Fotodiox. The weight and size of those lenses eclipses the size advantage of E-PL2, but its FLM of 2 gives me interesting set of focal lengths, e.g. 600mm super-telephoto.
As other reviewers already mentioned, AF does not work. It is not a problem in my case, because E-PL2 allows me to MF easily and precisely. Lack of aperture control is a bit of problem. I just need to use it in the situations where fixed aperture is acceptable. The quality of the adapter is not great, but I think it is what I expect from $30 equipment. It is a relatively simple piece of hardware anyway.
I am not sure how practical it is to use a big EF lens on micro four-thirds, but it sure is fun to play with.

You have to work wide open. Thats kind of a bummer. I guess if the lens is sharp enough its ok.

It was really nice to find this adapter. We have a Canon lens that we need to fit on a Lumix camera. This adapter worked nicely. If you are looking for an adapter be sure to look closely at the specifications to choose the right sizes and types for the lens and camera, there are several options. When the shipment arrived the box was dented and damaged but the adapter was in working order and seems to work just fine. The price is certainly right.

The Fotodiox adapters make the cheepie Chinese knock-offs, look and perform like toys.
A very fair price for a well made product. Bravo Fotodiox!!
They're not quite Novoflex quality but they're not far off.
At Novoflex's price point, you'd think a team of over compensated German bankers were punching time clocks and sitting in front of lathes - cranking out lens adapters.

Lens adapter securely mounts Canon EOS lenses to my Panasonic GH2 with no problem at all. Easy to change lenses, nice piece of equipment.

An excellent adapter that allows one to use their Canon EOS lenses on Micro Four Third bodies, you obviosly lose AF which is known. The only thing is the adaptor release switch for EOS lens lock can be a lil stiff.
