Olympus MF-1 adapter

Product quality and build is what you expect from Olympus. Great! Packaging was a nice surprise as it came with it's own case and securely protected. Arrived on time and ask expected.

Glad I found Adorama

Third time was a charm. Got the right adapter and I can now use my old OM lenses on my new OM camera. P

Fits Exactly and Tight

Like most Olympus accessories, it's expensive but luxuriously made. You get what you pay for. It comes with a box with blue silky lining. The adapter has a heft to it. Well made and won't scratch or make your lens stuck, which could happen when I used a third-party option just because I didn't line up the dots properly (on the field, I was in a hurry to get the shot). There is no wobble between lens and mount. It is very tight initially, but will loosen up and become exact fit after a few use.

Rock Solid Adapter

I use this adapter with my 500mm f/8 Zuiko Reflex lens. It is a solid fit that locks in both to the camera body and the lens, but is easy to disconnect from both if you have other lenses to employ. It comes in a nice box that would be great for storage, but my MF-1 lives on my 500 all the time, so the box is in the drawer. :) Focusing manually can be a challenge without the viewfinder aids of an SLR camera, but with the bright viewfinder of the E-3 and practice, good focus can be achieved. And of course on image stabilized bodies, the IS can be activated and set manually for the lens focal length. Definitely worthwhile if you have OM lenses.

Works great!

I was delighted to find this product so that I can use my old OM lenses with my new E-410. No discernable loss of image quality, works with all my old lenses for my OM-1

Excellent investment

Zuiko film lenses are wonderful, and if you have any and want to use them with your E-series camera, then this is the least expensive way to continue to use your film investment. I've used it with the E-300 and the E-3, and it allows, with certain limitations, to use non-digital lenses.

Don't waste your money!

This adaptor extended my 500mm mirror lens to where it cannot focus at all in all planes. Either vertical lines focused or horizontal lines focused, but never did they both focus at the same time - save your money for new 4/3 lenses instead.

Expands the options for Olympus DSLR use

Having used Olympus SLR's for almost 30 years, I have a few lenses from that system. This allows me to add these to my digital system. I've used it with 50mm 1,4, 50mm 3.5 macro, and 300mm 4.5 mainly. But there are other lenses available on the used market to expand your options. I've been able to add my E1 to my T-mount telescope for some great moon shots.
