K&F M12121 Canon EF Lenses to M43 MFT Lens Mount Adapter
Does the job
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.
