I thought I had my mind made up and I was getting the D50. I stumbled upon a new D70s. I was planning on getting the 18-70mm lens already. The D70s kit would save me about $200 which would be nice to put towards some more lenses. I am just a point and shooter right now. I have no idea what "noise" is or what it looks like. I have never post processed a picture, just used it as it is. My photos are for capturing family memories. How much bigger is the D70s compared to the D50?
