Question: Works with EOS 70D?
Document: I bought this because I received as a gift an old Olympus OEM with one 50 mm prime lense and one 85 mm prime too. I wanted to be able to use both lenses in my Canon EOS, so I purchased this adapter. Since then, the 50mm has become my favorite lense.
works perfect and is sturdy. cant beat the price for the quality. i use it everyday for my job :)
Off course, you need to know how to shoot in manual, since you don't have automatic with OEM lenses, but that works for me.
It's just a little loose fitting on mycanon 60d.Most of the cheaper adapters are I'vebeen told.But it works just fine.
works great, now i can use my olympus lenses on my cannon camera. just need to work with it to find the propper settings and you're set !! !
This lens adapter does what it says. I can now use my marco olympus lens on my canon. SO HAPPY!It was a little tight to begin with. But now it works great.It's worth the $10
Mounts, and works perfectly with both Canon reduced frame, and full frame cameras. A small screw stops the lens down to the chosen aperture. Multi-segment metering works fine, and Olympus lenses focus to infinity.
This is a great fit. It works good with my Sigma OM, and 49mm OM lense. It has a slight mismatch with my doubler adapter, yet works good with some patient work. Comes off with ease as well. Good product and my lenses are both from 1983. Cheers.
I purchased this adapter and was fairly happy with it. I have several manual Olympus lenses including a Sigma 400MM lens that I wanted to use on my Canon 40D. It works good and takes great pictures. No problems so far.
To keep it simple, this works on my 50mm Olympus f1.8. I love that little lens, so naturally I had to get an adaptor. The adaptor slid on to the lens no problem, but is a little tight fitting on the body side. I ended up sanding the outer edge to get a better fit.
Answer: Yep this works with all Canon DSLRs with EF mounts
