It's such a small body that with larger lenses it becomes a hassle. Maybe an extra grip would help. The buttons back are nice but flushed with the body. It currently prevents me from going BBF. Planting a small ball of sugru on the AF-ON would work wonders I believe.On the GX80 ergos, is it the grip or control/layout? I added a fotodiox grip/plate and it feels pretty good. I think I'm going to add a thumb grip if I can figure out which one. I use back button focus so it may block it. 50/50 on that.
