K&F Concept Lens Mount Adapter Compatible with Canon EOS (EF/EF-S) Mount Lens to M4/3 (Micro Four Thirds) MFT Olympus Pen and Panasonic Lumix Cameras

Well made and works great.

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!

Works great with an old EF lens I wanted to use with my M43 camera. Build quality is good but it is a bit tricky to screw on to the lens. Once on, it feels sturdy though. Note that there is no focusing or electronics pass through so you’ll need to manual focus - but for the price I can’t complain.

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.

Family had a bunch of Canon lenses for the photo camera we've had for years (even a cool fish-eye lens) and I just purchased a Panasonic Lumix G85 as a graduation gift. Wanted to find an affordable adapter so I could use the 7 different lenses and this works perfectly! I tested all of them and was so happy to have all these options instead of having to save up and purchase a bunch more lenses down the road. The AF is something I haven't figured out yet, the Panasonic AF is also a tough subject for me since I practically just got this camera. Maybe someone out there has advice, but for what I wanted, I definitely got it!

I bought this lens with looking at reviews for it saying it is amazing for the value and for DSLRS I believe it is. However for Blackmagic users, this adapter would only work if the lens has a manuel Iris ring (Rokinon, DN, etc). I had the expectation that my canon lenses would focus on my bmpcc4k with the manuel ring but the blackmagic cams dont have built in Iris control, it requires it from the lens itself, so I was disappointed. Again if theres anyone interested in buying this for the blackmagic cams its worth it only if the lens has a built in Iris/Aperture ring.

Don't be confused by what this adapter does and doesn't do. Many reviews and answered questions are misleading. Just to be absolutely clear, this adapter works with the Panasonic Lumix G7 body and Canon EF lenses, NOT Canon EF-s lenses. If your lenses have the RED dot, them this adapter will work for you. If they have the WHITE dot, then you will not be able to focus the lens when mounted and should not bother with it.K&F has a good product here. The ir build quality is very good and the adapter fits very snug on the camera and Canon lenses. K&F's description of the product is also accurate... it's for EF lenses. Just be advised that this is a mechanical adapter... it has NO electronics and your Lumix G7 will not be able to auto-focus an EF lens nor will it be able to adjust the aperture. Once an EF lens is mounted, you are on your own in the camera's manual mode only.Once you mount a lens on the G7, you will need to go into C mode (custom) on the settings dial and toggle down to turn ON the setting that allows the camera to operate without a lens. That will allow the shutter to operate. Unfortunately, the adapter does not come with instructions so this isn't obvious.Sadly, my EF-S lenses are the smaller ones that I wanted to use with the G7 and that is why I bought the adapter. Shame on me for not realizing that they are not what it was made for. Don't make the same mistake.

My buddy had one of these let me borrow it. After using it, I had to buy one of my own. What I especially like about this is the build quality - it's got a VERY satisfying feeling when connecting it to my MFT cameras. It's very sturdy holding the lens (I typically use a, admittedly light, 50-250mm EFS lens with it).This is a "dumb" lens mount. So your aperture is fixed at what you left it at, stabilization won't work, and you're stuck with manual focus only. This is cool as there's "smart" versions of these than I've read can mess up your camera. So I have peace of mind while using this. Just be sure to set your camera to work with "No Lens".I use this on an Olympus OM-D E-M10 m1 and a Panasonic G85 - works great on both.
