I think I will go with the Panasonic Lumix S5II. I own a nice 50mm Nikkor lens I could use for portraits or artistic video shots with the Lumix, I just need to buy an adaptor. Two questions: I own a Sony ZV-E10 with a Sigma 30mm. At this point, should I sell it or should I keep it? Also, which Zoom lens should I buy? Panasonic 24-105mm f/4 or Sigma 24-70mm f/2.8?
