If you went from D70 (or equivalent) to D 1 / 2 series and you kept the smaller body, what is the USAGE ratio between two. I know it all depends what, how and when you shoot but if you have to provide general feedback, what would it be ? I'm thinking about D 2 series and I'm curious how long I would actually need the smaller brother to stick around. I really enjoy D70 b/c of Flash Sync Speed 1/500 and wireless TTL commander/remote mode. It is really useful in aquatic / fish photography. What were they thinking building D2X's with 1/250 ?. So, back to original question. Share your experience.
