You mind buying used?
Chances are we want you to buy a Fuji
But taking your budget in mind, I'd suggest the Sony a6000 again. The sheer amount of them on ebay simply makes them really cheap.
≈ 270€
For portraits, a 50mm M42/CanonFD/MinoltaMD lens. Vintage manual lenses (The Pentacon 50 1.8 says hi), can be found on ebay for dirt cheap.
Adapter ≈ 15€
Lens ≈ 40€
Wide angle lenses are kinda expensive, so maybe try a 25mm and see if you need something wider. I have a 12mm, but hardly ever use it.
The dirt cheap Neewer 25mm 1.8 I use alot as walk around lens is also available for sony e-mount
≈60€
For manual lenses in general, there is always the chinese. They have become really good. Just look around on Amazon for
7 Artisans and
Meike. Great little lenses if you don't mind manual focus. Only the wide angle will set you back more if you decide to get one (>150€ i'd say) Best thing I'd suggest you to do here, is to just use the kit lens the camera comes with, it's wide end will be just fine for starters.
There is so much shit you can buy for that kind of money though, see what
@s4tch comes up with.
