My combination for this week will be the D300 and AF-S Nikkor 14-24/2.8G ED. It will be interesting to see what I can do with this lump of glass on DX. It might work well as I used to use a 20-35/2.8 in the F4 days and this gives approximately the same view.
If anyone else wants to shoot any single lens with me for a week, feel free to post what you get in this thread.
