Is the laowa 6mm f 2 zero d mft hard to focus manually?
The Laowa 6mm f/2 Zero-D MFT is manual focus only, so you turn the ring yourself and there's no autofocus to fall back on. The good news is that it's very wide. On Micro Four Thirds it frames like 12mm on full frame, and f/2 gives about the depth of field of f/4, so you have more room for error than you would with a longer, faster lens.
If you'd rather not focus at all, zone focusing works well with a wide lens like this. Pick a distance, stop down a little, and let the depth of field cover your subject. The street guide walks through the method. You can see the full specs and the list of compatible cameras on the Laowa 6mm page.
