So, I have everything ready for the eclipse. I went out with my Solar Lens filter, X-T2, 100-400 lens and extender. I set the camera to f/8.0, 1/125th, ISO 200, manual focus, 3-shot AE bracket, CH, and handheld a few shots. What I discovered is that I can't determine the focus. The focus distance and DoF indicator is not visible in manual focus. I cannot use auto-focus, and I can't see anything on the sun to manual focus on. There is no distance scale on the 100-400. I'm only trying to get the focus set to infinity. How do I display the focus distance? I must be missing something. Do the rest of my settings sound reasonable?
