I'm getting a gig photographing the insides of manufacturing factories in other countries for a large company. Here's my current gear list. Nikon D300s AF NIKKOR 50mm f/1.8D AF-S VR Micro-NIKKOR 105mm f/2.8G IF-ED AF-S VR Zoom-NIKKOR 70-300mm f/4.5-5.6G IF-ED AF-S DX NIKKOR 18-55mm f/3.5-5.6G VR Tokina 11-16 f/2.8 IF DX ultra wide angle Nikon SB-600 Just wondering if anyone has ANY tips on cost-effective changes to this lineup...I'm not made of money, but I want to do a good job. I anticipate low light and cramped conditions...dark wedding style. If I had to, would it be more effective to sell my D300s and get a D700, or should I get some faster lenses? Thanks!
