Hello peoples... I am in the market for changing/upgrading my camera. I currently own a Nikon D600 with Tamron 24-70 f2.8, Nikkor 80-200 f2.8, Nikkor 50 f1.8, Samyang 14 f2.8 (manual focus) and Lensbaby Edge 80 with Composer Pro. I shoot as a hobby, so I don't want to go for the D800 or D810. I was thinking of upgrading to the D750, since I have invested in the lenses (the Samyang and the Lensbaby are recent purchases). However, the only thing stopping me is the weight of the camera, most of the times I don't bother carrying my camera because its too heavy to carry around for a night out with friends or family. I am looking at the Fujifilm X-Pro 2 but the only thing stopping me is the investment in lenses. So up until I end up with a couple of fujifilm lenses can I use my Nikon lenses with any adapter of sorts? If yes, what would be my best option?
