Which beginner cam would you recommend?
Depends on what sum of money you are willing to spend @art-universe. If you do not want to spend much, probable choice would be one of Panasonic's Lumix cameras, or Sony A6xxx. Former has largest possible optics choice, latter has a better sensor.
Also, excellent choices would be Fuji X-T20, Canon M5 or Nikon D3300.
Hey @photo-trail - thanks for your respond. My budget limit is around 600-700 and I thought maybe a G70 body with some m42 lenses, because the cam would be also good for videos. What do you think? My dream would be a GH5 - but with a nice lens and a speedbooster it is quite a sum of money and too much for me.
