In the next few days I'm gonna buy a new DSLR...either the Sony Alpha A100 or the Nikon D80. Due to the price of the body and additional lenses (should I choose to get them anytime soon), I'm leaning towards the Sony. Their are two big differences I'm wondering about. 1. Image Stabilizer: Sony's is built into the camera where with Nikon you have to spend a few hundred extra per lens to have it. Advantage Sony. 2. Metering Thingies: I know the light meter is used to determine how to balance aperture, shutter speed, f/stops. Sony's has a 40 hexagon planar system, where Nikon has some sort of 3D system. Apparently the advantage goes to Nikon. I don't really have a question about the IS/VR stuff, but I do want to know what the advantage is to the 3D metering versus Sony's planar version. I've just figured out today what the light meter is used for, so I'm guessing having the Nikon over the Sony won't be such a huge deal for me personally...or will it? I know there's tons of variables when choosing a camera, but generally is the 3D metering so incredible that I should spend the extra money on it? I'm thinking no.
