Nikon’s camera sensors come from Sony.
Really? Huh, always thought they made their sensors in-house.
Looked it up and apparently they did at some point, but seemingly only in their professional cameras (D2h, D3, D4). But Sony isn't their only supplier when it comes to sensors apparently.
I honestly don't think I would spot the issue he was talking about without comparing photos side-to-side; I'd probably be perfectly happy with a Sony alpha or something, but somehow I'm skewing more towards getting a Canon now.
