Pro Mount Adapter for Canon EF Lens to Micro Four Thirds Micro 4/3 M4/3 Panasonic Pen Olympus E-M1 II E-PL8 Pen-F E-M10 II E-M5 E-PL7 E-P5 E-PL6

Fits my Olympus PEN Epl-7 and Canon EF lenses perfectly, as well as my Rokinon manual Fisheye lens. Now I can use my Rockinon and Canon lenses on my PEN for special photography, without needing to re-buy separate lenses just for the PEN. I use it for these extra cases, I do not use it for everyday photography with the PEN. For that I use the standard lenses that came with it. But for that special fisheye shot, or the extra distance gained by attaching my 70-300mm on the smaller sensor PEN, it's perfect! I even attached my Canon lenses onto my macro tubes which attached to this adapter for the PEN camera and got some great flower shots! Be careful of the weight of the lenses as this point on your camera. Also be aware this converts any electronic lens to manual. My fisheye was already manual with an aperture ring, so this was perfect. However for the Canon lenses I do not have an aperture ring, therefore it is set at whatever aperture you choose before you attach the lens. You can set the aperture to whatever you please by attaching the lens to your Canon DSLR, setting the aperture on the camera body, pressing the preview button so the lens stops down, and then holding that button while you remove the lens. The lens should have that aperture held, even as you reattach it to the mount adapter. I personally have had no trouble attaching or removing lenses or macro tubes with this adapter. I would recommend it as a good adapter if looking to attach Canon EF lenses to an Olympus PEN Epl.

I say "inexpensive" rather than "cheap" because it is a really solid build. No IS, no AF, no speed boosting. 100% pure manual. But for the price? Seriously, if you have a MFT camera just go ahead and grab it as old Canon lenses can be found everywhere. I have it on a BMPCC4k and it works fine with some old lenses I have. Nice and solid connection. Only thing to remember is that a lot of modern lens CAN work in manual focus, but a lot of them don't have manual iris. But for the price and working with older lenses, it is inexpensive and works as expected with no wiggle or rattle.

Works great and at $12.58 USD it's priced right too. If you need autofocus though, use something else. I connect my 400mm f5.6 to a m4/3 body that has in body image stabilization for a super light, small, stabilized 800mm setup. It's a fun challenge to shoot birds in flight and other wildlife with this setup. When I get it right the results are outstanding. Like I said, you'll need to focus manually, but a lot of mirrorless cameras have focus peaking that tells you when your subject is in focus; it's fairly dummy proof. I have sold prints of photos that I took utilizing this adapter which says something. So if you don't absolutely need autofocus (didn't have it in the old days) this thing works fine.

Works great able to mount cannon lens on my Lumix G7 for Manual focus lens only..

I bough this to use with my Panasonic G7 and it works as expected. This is one of the better built and more sturdy of the cheap lens adapters.

Works perfectly! I'm using it for my Panasonic Lumix G7 connected with my Canon 50mm f/1.2 lens.
