If I were most interested in this focal length for portraits, I’d probably want the Zuiko Digital f/1.8; that field curvature will help throw everything other than the subject out of focus. For landscapes or architectural shooting, the flat field of the Panasonic f/1.7 would be an advantage.
You might ask the very pertinent question, “The MTF is higher away from the center at a different focus position than best center focus. What if I focus out on the edges”? Well, you’ll get a much sharper image. The lens is very sharp away from the center; it’s just that the sharp area is in a different focus plane. But we can graph the best MTF for each point and get something very different; a graph that shows how sharp the lens could be if you focus off-axis. We call this the BIF graph, for Best Individual Focus.
