On my m4/3 system I am using a Fotasy brand, but I'm wondering if there is something better out there in the market. It's been a while since I've looked adapters in the mirrorless world, so I am not sure. I don't want to get something overly expensive, but do want something reasonably accurate. Thank you. BTW I will be using MD lenses. Edit: I just noticed that on ebay I can get from ebay seller ADPLO an adapter with a thumb grip for 21 shipped. Is that a good product/deal?
