I forgot to add it has the standard lighten/darken control around the light sensor.
Only seven images including the ones in the video. I used three testing another camera.
It was super windy and the old 400mm definitely does not have image stabilization. I got lucky during a short lull.
Sony A7, Aperture Priority, 1/60 second, Fotodiox FD-E adapter, Prospec 400mm (FD) @ f8, Vivitar 2X Teleconverter
I’ll try some exposure stacking – bracketing gave me some good sky-dark mountains and the reverse.
