Because some of the newer models are going for fire-sale prices lately, I must admit my interest in Samsung's NX series of cameras has been piqued. But can any NX owners and enthusiasts give me some basic information if I'm thinking of picking one up? Is there a particular model, even if not the latest, at which image quality goes to the next level? Is there a "just buy it" model? Is the 20-50mm lens better, worse or about the same as the 18-55mm? Of course, the 30mm f/2.0 is the lens to have eventually. How are Samsung's lenses overall? Does Samsung make them? How are the rear LCDs on the Samsungs in bright daylight? Is there a point in the model progression at which the LCD jumps to the next level? Any particular weakness or strengths to the entire line? I've been aware of Samsungs cameras for a long time but have never really bothered to pick one up and play with it at length. I am very curious but I'm also trying to keep costs down with any potential purchase.
