Yes, it kinda makes me think my D810 is a small entry level camera in comparison!
The first thing I noticed after opening the package was the weight! I used to think the F801s and F100 were chunky cameras. If the finance Gods are nice, I may lash out on an F5 next, although a little scared about the sticky rubber issue, if it effects them in a similar way to the 80, 100 etc?
