Hey folks.
I've got an inexpensive (but well built) lens that is not even CLOSE to having its correct MFD.
The lens is an Oly 75-150 f/4. (I want a cheap, light-ish walk-around lens in this aprox FL)
It's listed as having a 5'2" MFD, and this was just confirmed by an FM'er.
I'm getting slightly over 8', and I've tried four different brands of EOS adapter.
This lens also focuses past infinity, though just a tad.
The adapter is probably too thin(to guarantee you can reach infinity with your lenses) so it focuses past infinity, the amount you need to turn the focus ring to get to get back to infinity is unfortunately lost at the MFD, infinity adjustment may or may not help.
Some adapters are screwed together, those can be taken apart and shimmed.
For one piece adapters, you are stuck, there are a few options, infinity adjustment of the lens, asking the adapter seller if they have any with the correct thickness, or in some cases you may be able to shim the lenses mount by removing the mount and adding a shim, just keep in mind that any modification to the lens will cause it's infinity to be unreachable on the proper mount(eg film body)
