Flash recommendation: it32 vs. Lux Junior II (Mirrorless-Lumix & Analogue Film Cameras)

Hi!

I'm looking for a run and gun little mini flash. I was really attracted to the Lux Junior II which is currently on presale, as it seemed to have all the features I am looking for. The IT32 is also very appealing, as it seems like a complete flash but much more compact.

I liked the idea of buying the im30 etc. but felt I wanted a little more functionality, and since I use a lot of very wide angle lenses, I was worried it might create that lens shadow (too low on the camera body).

I recently bought Panasonic Lumix S5 so would be looking to mount it on there, as well as my many various film cameras (Nikon F / Rollei 35 / etc). Are godox flashes compatible with film cameras?

I would appreciate anyone's thoughts and opinions on the matter!
