Windows 7-compatible versions of Nikon Transfer, Nikon ViewNX, Nikon Capture NX 2 and Nikon Camera Control Pro 2 are to be released, according to the document. Compatible digital SLRs include the D3 series, D2 series, D300 series, D700, D200, D100, D90, D80, D70 series, D60, D50, D40 series, D5000, and D3000. Supported cameras will include all Coolpix P-, S- and L-series models, as well as the Coolpix SQ, 995, 8800, 885, 8700, 8400, 7900, 775, 7600, 5900, 5700, 5600, 5400, 5200 (2), 5100, 5000, 4800, 4600, 4500, 4300, 4200 (2) , 4100, 3700, 3500, 3200, 3100, 2500, 2200, 2100, 2000. Most of these cameras will support USB transfer via both MTP / PTP and USB Mass Storage on most systems, but there are a few exceptions. The Coolpix L1 and 5200 will not work with PTP transfer on Windows 7, and will instead require use of USB Mass Storage transfer. The Coolpix 775, 885 and 995 will require a standard connection method, as they won't offer a choice of USB transfer protocol. The D1-series cameras will not be supported for image transfer in Windows 7, and will hence require use of a card reader to transfer images.
The company notes that it is currently testing compatibility of Windows 7 with certain other products, and doesn't state whether or not it intends to make them compatible. On the software side, these include Nikon Scan 4, NIK Color Efex Pro, my Picturetown Utility, WT-4 Setup Utility / Thumbnail Selector, WT-3 Setup Utility, Wireless Connection Utility and Image Authentication Software. Hardware currently in testing include the Super Coolscan 9000ED, 8000ED, 5000ED and 4000ED film scanners, and both the Coolscan V ED and IV ED film scanners.
Finally, the company has confirmed that certain products will not be compatible with Windows 7. For software, these include Picture Project, Capture NX v1.x, Camera Control Pro v1.x, Wireless Camera Setup Utility, Nikon Capture 4, Nikon View 6, Coolpix Remote Control, and DVD Show. Unsupported hardware on Windows 7 includes SCSI or serial-connected products, and obviously the applications for these products won't be compatible either.
