Thank you. I have the Novaflex adapter set as my choice if I go F mount. I shoot stills with Nikon and know down the road I may be using a Nikon for a B video camera (who knows with tech upgrades - maybe A?). I'd hate to be stuck with a lens that can't adapt. Great to hear about the solid mount with that adapter. Down the road I'd like see about getting Zeiss ZF.2 glass, but for now spent quite a bit on computer work station, lights, audio, rig, on camera monitor and next big bite of starter camera and Cine lenses. Not to mention the (if it is tested to be as advertised) the Atomos Shogun. No wonder a friend of mine in the industry laughed when I told him I was going to buy the gear for film making. Of couse he said just rent gear, but I want to learn and produce work on my (non rented) time and own gear. That was my approach to my now professional photography business and it has served me well.
