My boss wants to get a "nicer" camera to take pictures of product. I can do these shots with my D90 just fine, but he wants one for the company, except the budget is a bit lower. He's forking out up to $600 for the rig. I run a 18-105VR and it works nicely for the shots I need to take, but is there a better lens for this type of work? Also, what camera would be ideal for this, given the budget? What kind of lighting is suggested? (I was thinking shop lights and white bed sheets (what I use at home) We'll also need a decent tripod. Any suggestions are appreciated, thanks!
