I got my FD/FL adapter in the post last night, so I went out this morning to do some tests with it and my FL 28 mm f/3.5 lens. The results were horrible, awful; and I don't recall back in the film days, that this lens as all that bad. I'm pretty sure that much of this was a focus issue, and I use manual focus pretty successfully with both the kit lens and my 14-55 Mk I DSLR lens. But they both communicate quite a bit with the body. The bare bones FL lenses simply don't communicate. So how do YOU use the Canon adapters with an E-M10? Do you focus with the that open ring set to Open? Do you focus with the ring set to closed? I found focus peaking to be a bit unreliable with this lens. Is there a flow of work you guys use with legacy lenses?
