By pure chance I happened to walk across this scene on the other side at Feldberg, Ts. while I carried my EOS M50 (APSC) with a vintage 100/300mm (no IBIS) Ultrasonic Lens. Which in this combination calculates to 450mm viewing (due to the APSC Sensor). Nevertheless only short exposure (1/1000 to 1/2000) was able to handle the pics, handheld.
I was really happy with the result and the colours this vintage lens delivered!
