Perhaps a future sticky, centralizing the info for my sake and others'...

What M43 lens adapters do you have or have tried?

Vital info: adapting to what, brand, cost, build and mechanical quality, and have you noticed any problems in operating with certain lenses (focus range problems, aberrations of any sort) or verified that what you have works well with a particular lens

Contribute whatever you can. Thanks

This is what I use for my old Canon FD lenses on both my GH2 & AF101. They are the cheapest that I found on eBay but work great. There is an adjustable ring labelled Open/Close that allows you to adjust aperture smoothly without steps.

It is described as a "Canon FD lens to Olympus E-P1 E-P2 micro 4/3 Adapter"

I bought a Canon FD from JNFinance on ebay, and it basically worked and was cheap enough. If budget conscious, sure buy it... However, it had a split ring which if moved could inadvertently change your aperture, regardless of the setting on the lens itself. It also focused past infinity. I found I was missing wildlife shots because I could not just "roll to infinity" and start taping. Too much time was wasted fiddling with things.

While I hated to spend more on the adapter than most of my lenses each cost, it became necessary andi am happier with this kit.

Not likely to be a highly-sought-after item, but nonetheless...

Got a Olympus OM-m43 adapter by "Pixco." Got as part of a package deal second-hand, but can be found via eBay for ~$20. Completely average... clicks pleasingly solid onto body and lens, but there's a less-than-joyous amount of play between lens and adapter.
