I'm also having this problem and it's really frustrating and hope someone has a fix soon

Anyone using any of these "D-Tap Battery Power adapters" for their GFX?  Are they worth it? Which one are you using. For example "Neewer VP-NPW235 to D Tap NP-W235 Dummy Battery" Thanks in advance, -Ken 

Hey guys I'm trying to adjust to this camera but it's driving me a little bit crazy because anytime I press the ISO button and adjust my ISO it flips to this ISO only screen and it's not showing me my metering.  I'm trying to adjust my exposure yet I can't see my light meter  when adjusting my ISO.  thoughts? I'm wondering if because it doesn't have a dedicated ISO dial that this is how it defaults and there's no fix. If so it's a bit of a dealbreaker for me. 

It might just be you need to get used to a different workflow with the new camera. It's bound to feel different with a new camera but that doesn't mean that it's not for you. 

The X-T5 does tend to show up any weaknesses with lenses especially the older ones.
