I use a F6 extensively for a couple of years. I bought it as a way to delay my entry (kicking and screaming) into digital. It replaced a F100 and F5. It was a wonderful camera and wonderful experience, but the inevitable happened and I bought a D200. In hindsight (except for the digital era learning curve and joy of using that camera) I should have kept the F100. It provided much of the same imaging benefits. You get many similar joy-of-use high-tech benefits of the F6 from a current DSLR.
Moving to the D200 from the F6 in a control sense was easy and my D700 now is my mental replacement for the F6. However, the pressure to go digital was just too great and the hassle of retraining anyone in my film workflow to meet the results I wanted was just too time consuming and I am now exclusively digital and overall happy that I've moved on from the F6.
Roger It's still, ISO, aperture and shutter-speed, right?
