I still shoot film, so this tidbit that is mildly interesting... using the D850 as a film scanner, although it seems like the scanned image results in a jpeg file. I would have preferred that it generate a RAW image. In any case, I will likely be getting one by Q1 2018, depending on availability. I'd be interested to hear from early adopters. "Use the D850's 45.7 MP back illuminated sensor and Live View for Stills Mode as a negative film scanner with the new optional ES-2 Film Digitizing Adapter on a compatible Micro-NIKKOR lens. You can copy slides or negatives one at a time. Digitize the gems from your film days." "The ES-2 is a Film Digitizing Adapter that lets you easily convert your film images to digital. Taking advantage of the high-pixel count of the D850's 45.7 MP, the Film Digitizing Adapter lets you convert both 35mm slides and negatives to digital files. Using a lens such as the AF-S Micro NIKKOR 60mm f/2.8G ED attached to the D850, the camera's digitizing function automatically reverses the colors and stores them as JPEG images. This once time-consuming process involving a film scanner can be done much more quickly. For negative strips, use the FH-4 Strip Film Holder with the ES-2 and for slides, use the FH-5 Slide Mount Holder with the ES-2."
