The Fotodiox Canon EF Pro Lens Adapter with Built-In Iris Control for Micro Four Thirds Cameras is a high quality adapter that allows you to mount a Canon EF mount lens to a Micro Four Thirds camera body. It features a brass construction with a stainless steel finish as well as the ability to focus to infinity. This works with a leaf spring system for a secure attachment. Additionally, this lens features iris control from f/1.7 to f/22.

This adapter will not allow for electronic control over lens functions. In order to function with automatic metering you will need to place the camera in manual or aperture priority mode, where the camera will utilize stop-down metering to determine the appropriate shutter speed.

Note: This adapter will not fit the Olympus OM-D E-M1 Mirrorless Micro Four Thirds Camera.

    Canon EF Pro Lens Adapter with Built-In Iris Control for Micro Four Thirds Cameras is rated 3.7 out of 5 by 39.
    Rated 4 out of 5 by from Good for the price I bought this for my Blackmagic pocket cinema for use with Canon EF-lenses. For the price point, this little adapter offers quite a bit. Although not as fancy as higher-end speed boosters, this little adapter certainly does the job. Build quality is decent, and made completely of metal. The iris blades are crafted well enough to give you those nice circular bokkeh orbs, unlike other cheap adapters. My only gripe being the lens release switch. The sutble knob is not the most ergonomic, and digs into your flesh whenever you use it. The one drawback would be that there are no included caps for storage. I would recommend buying your own inorder to protect the iris blades, and keep some dust out.

    Rated 5 out of 5 by from Works well. Nice build quality I was pleasantly surprised with the build quality. The aperture blades form a nice bokeh, very round, lots of blades. I also like the ceclicked aperture ring and how smooth it operates. Fits nicely on my BMPCC and EF lenses. Solid fit. There is no optics in this so there's no quality loss whatsoever, just crop loss as is understood attaching EF lenses to Micro Four Thirds systems. Shipping was impeccably fast to Canada. I was seriously thinking it would take a little over a week, but got it in slightly over 2 days. This is my first purchase from B&H, I've always purchased these types of products either locally or if not available, through @. B&H has definitely won my business on this one.

    Rated 5 out of 5 by from Great Adapter! I bought this lens adapter to use EOS lenses on my Blackmagic Pocket Cinema Camera. I was interested in this model particularly because it has the manual iris built in. When using EOS lenses I am forced to set the aperture wide open on a Canon DSLR and have no way of stopping down. With this adapter I gain this function. The ring is smooth and easy to adjust and everything mounts solidly. Some people had complained about vignetting on their m43 cameras with this adapter but I have had 0 problems with that on the BMPCC. Its a great tool for someone who can't afford the high cost of the EOS to m43 Speedbooster with active mount, but still needs control over how much light is getting to the sensor (everyone).

    Rated 2 out of 5 by from The Jury is out Well I had high hopes for this as I am a Canon user with lots of Canon glass and recently purchased the GH4. My first impression is not a good one. I found it very difficult to get sharp focus using this adapter even when I was stopped down to f16 or f22! I was using my Canon 70-200mm L series II lens which is the sharpest lens I own. Anyway I haven't used it once since I tried it out. I'm not sure I will ever use it and that bums me out. I think I will just invest in new glass for micro 4/3's. I imagine others have had great luck with these adaptors but so far anyway my luck has not been so good. I haven't given up yet but I'm not excited about using it anymore.

    Rated 3 out of 5 by from A great idea w notable problems - vignetting/soft focus I purchased this specifically to use on my BMPCC. I shoot a fare amount of commercial work with it because of its small unobtrusive profile. As a stills shooter, I'm a Canon 5DmIII guy, so I have EF mounts and would rather get more use out of the glass I already have. I felt like Metabones was playing it fast and loose with the term affordable so I went this route.FIT: The fit was great. No play, no wiggle. Rock solid.EASE OF USE:I knew this was entirely manual going in. Shooting video, manual is king anyways, so while I list this as a con, it's only noted for the sake of reference for those slacking on their homework.The f-stop ring is like butter. It reminds me of a nice drag on a fluid head. It can also be utilized while shooting.IMAGE QUALITY:Here is where I ran into my major qualms. Soft Focus - Obviously glass has a bit to do with the image quality, but the focus was dramatically softened while using this adapter, even when I double checked it with the focus peaking on both the BMPCC and the field monitor. Using Canon L and Zeiss glass, pro grade lenses, not prosumer glass. The Zeiss 50mm 2.0 makro-planar in particular is TACK SHARP on the 5DmIII...not so here. (Image below)Vignetting - The Zeiss received no vignetting but the Canon 24-105L and 70-200L did. Wide open, the vignetting is far less, so you better have a variable ND filter with you. Stopped in the 20 range, you're going to look like an amateur with the sheer amount of vignetting from the BMPCC. See pics below.I guess I'm shelling out $ for the speed booster...

    Rated 2 out of 5 by from Not all I'd hoped it would be. This is a well-built, solid piece, and the aperture ring turns nicely. I have to pull an EOS lens off a powered mount wide open without powering down the camera to get the aperture to be open in on this adapter, but that seems to work. The real drawback is that I really bought it to use with a Tokina 11-16, and I don't get infinity focus at the wide end, and that's disappointing. The flip side is it can focus very close (which is of course not as useful). So I get some use out of this here and there, but it's not the solution I was hoping for. If I had it to do over again, I'd put the money into a 12mm mft prime.

    Rated 5 out of 5 by from Does what it says Works with all me EF lenses and allows me to mount them to my Panasonic GH4. No issues here.

    Rated 4 out of 5 by from Lacks Automatic Features, But You Ca Still Get Great Results I picked this up because I am starting to shoot 4k video on a Panasonic G7, yet I have some Canon lenses I do not want to let go of (ex: my Canon 50mm f1.8) I was worried after looking at the price and picking it up from the B&H superstore that it might be a little flimsy (it only came in a small cardboard box!!) However, once opening it up and further inspecting the adapter, I was surprised at how much weight it had and lost all worries about it's durability. When using this adapter, I first put on the lens I want to use, then attach the adapter (with lens) onto my camera. I've yet to have trouble with this method (knock on wood!) I keep my shutter speed at 1/50th for 24 fps (or 1/60 for 30 fps, respectively) Be Warned: The iris control is built into the adapter itself; it is separate from your lenses' aperture control, so your lens will stay open at it's widest aperture no matter what. I know it might sound crazy to some, but I originally thought that this adapter would control the aperture of my lens. However, this became a blessing for me, as I can set the adapter to a low aperture and still be able to get a shallow depth of field from my 50mm (see example photo.) Also, be ready to rely solely on using manual focus along with your camera's manual focus assist, as you will lose all autofocus capabilities when attaching this adapter (again, some might call this a no brainer, but I feel it's important to remind you.) I will admit, it has been a little bit of a challenge trying to properly focus my 50mm; I feel like that I will overcome it the more I use this adapter. Although this adapter lacks some features I usually find essential, for the price you cannot get a better deal. I feel it's an essential accessory to have in your basket if you own some great Canon lenses, but want to take advantage of the 4k capabilities Micro Four Thirds cameras currently offer.
