Nikon f4s or F100

I own both, the F4s looks better on the shelf and is more impressive to "play" with, but the f100 is a better camera to use.

Also the f4's lcd screen is notoriously prone to bleeding. LCD technology was still fairly new when it was designed, the f100 does not have this issue.

If you like the feel of a heavy camera, you should also consider the f5--like the f4 it's a camera that "feels like you mean business." The only problem with it is the hard to make out focus point selection, which they fixed with the f100. Focus point is selection is not a problem with the f4, as it only has one focus point.

I've an F100, F4 and a FM3a and I can never decide which one I love the most!!
I just love Nikons!!

Save your cash and buy them both

I stayed away from the F4 because of the size. Other than that, I think it would be a nice complement to the F100 as a do anything body. I love my F100 though.
