Jason, what's the simple mode to replace the Kapture Group box? I have a GX80III with a P45+ and love it. However, it's a bit clunky and don't use it too much, but it is a work of art and craftsmanship and I'll never get rid of it. I'd like to get rid of the Kapture Group box though if there's something simpler.
In the end, I'd agree that it isn't practical for most people, but I really don't care because it has a special place in my heart that none of my other camera have.
