Thanks everybody for the response. I had the chance to handle and shoot an 85 1.4G yesterday, and while the optics are absolutely superb, it did feel a bit like plastic on the outside. I guess I'm sort of hesitant that it's even a Magnesium alloy; it certainly doesn't feel like a D700 body. I don't really care in the long run, as long as it is durable. Any thoughts?
