Looking for some help. I want to upgrade my kit but not really sure what to get (or the best place to look!). I have a budget of £5000, but I dont really want to spend it all as I need a new laptop. Im a nikon user so has to be nikon, but that is the only stipulation. Im more or less decided on the d700, so its more ideas about lenses. Ive got the sigma 10-20 already, but thats probably the only one ive currently got worth keeping. Ill be shooting all sorts, so flexibility is the most important thing. Could also do with some sort of lighting. Any suggestions? Cheers, Will.
