Re: Nah
A few years ago I'd have agreed about Nikon, but they appear to be gasping in the diminishing pond. The only reason I don't think they are next is that Pentax have it worse. :-(
I dislike Sony as a company, not least for their frequently adversarial attitude to their own customers. They are having a lot of success with their full frame range though. If I ever opt for full frame it will probably be a used Sony.
