"Flim? You want flim?"
Sounds like you need a fast lens.
Decide on either 50 or 35, then I recommend one of: clean 50/1.4 Canon LTM, a CV Nokton 50/1.5, or a CV Nokton 35/1.4.
All outstanding fast lenses, that cost less than your budget. It does sound like spending less than 700 Euro will be welcome. 🙂
I recommend against the 35/1.2, due to size and viewfinder obstruction. Not exactly what Leicas were made for, IMO.

Great suggestions that I had in mind to suggest; also consider the Canon 35/2.0 LTM - my current favorite 35.
