Seeing the bridge at the 13 second mark startled me - Big River Beach - Mendocino CA. Damn. I stopped at Point Arena too. I was under that same bridge March 2023. I live 2 states north. I shoot the A7R3. Would you mind sharing the exact make/model of the adapters for the lens? I must Amazon as I think I have a couple of lenses of this mount I'd like to try. Thanks for the vid!
oh, and the Pentax to nex adapter is a Fotodiox that has a helicoid and accepts internal neutral density filters, but Pentax-NEX adapters are common enough I guess that you probably have one if you like adapted lenses.
