Hi, I recently swapped out my NEX 5 for an a6000. The camera is fantastic, but for some reason the MF assist won't activate when I have my Sony 75-300mm lens attached (I have a Sony LA-E2 adapter since the lens is not naturally an E mount). The MF assist works fine when my 18-55mm lens is attached, and the MF assist worked on my NEX 5 for both lenses. The MF assist is really important for me to get good crispness with the 300mm lens, so I'd greatly appreciate any suggestions to make it work. Thanks! P.S. I have doubled checked the MF assist is on, Peaking is off, and the auto focus will work so the camera is definitely reading the lens.
