Well, first off - it feels like a noob asking this. But: Laowa lens is mounted, but my gfx100s doesn't seem to be satisfied with the settings, because it's not possible to take a photo.
Can't find any good info on installing a third party lens - so trying my luck in some assistance here at the forum! The thing i find most odd is the display showing F0, and i can't seem to change that setting. I must be missing something quite basic prob? Advice or experience in using a third party lens and some necessary setting adjustments would be more than welcome. Thanks in advance for your effort!
