Thanks Chip and Akira.
This is from the "test roll" and the fine surprise is, that old FE is in perfect working order, especially the metering cell and the shutter.
Main challenge is the film itself : dust, damage (resulting in "bright pixels" or rather speckles). Not 100% satisfied with the lab, but I do not want to do the chemistry again.
Another shot from the 1st day, same FE + 50/1.8 AI; aperture was f/2.8 if memory serves. Man I love the texture of the HP5.
