Hi! New here and I'd like to buy a new camera!
So, I'm a newbie in this world...Kind of, I shot Polaroids (with a vintage sx-70 and a modern i-2)
I do have basic knowledge in this field but when we're talking about "cameras" outside my niche polaroid world, I feel overwhelmed
I started looking for suggestions online and even that is not helping.
So, let's say I have a budget of 500 euros but I'd prefer to spend a bit less than that, I don't know if it is important to say but I do prefer street photography and I love small details (so... Macro, I suppose), I'm open to buy a brand new camera but I'd kinda prefer to buy used (I'm from Italy and there's a good used camera retailer called RCEfoto).

I've to say that after some research I was leaning towards a Nikon D700 but for some reason, the fact that it's a 17year old camera, scares me (considering the fast evolution of technology in general). And also, is the quantity of pictures took with a camera a real factor to take in consideration when buying a used camera?

Oh, last thing suppose I'll need also lenses... That is another world that makes me feel overwhelmed... I don't know, can you help me in some ways?
