Now through September 28, 2013 Nikon is offering 30 Nikkor lenses at up to $300 off with any DSLR purchase. The offer is combined with the current $200 instant rebate on the D800 body, making this the best time to buy a new Nikon camera. Two speedlights (SB-700 and SB-910) are available at a discount, as are the 1.4x and 1.7x teleconverters.
Some of the lens discounts on popular lenses include $100 off the 50mm 1.8G ($369), 85mm 1.8G ($396). Zoom lenses include $300 off the 24-120mm f/4 VR ($996), 70-200mm f/4 ($1096) and 70-200mm f/2.8G ($2096). And $200 off the 24-70mm f/2.8G ($1686). If you plan to buy a few lenses, you could essentially get one of the lower priced DSLR bodies (D3200 or D5200) for free.
