Chris, best I can tell is that the f5 is alot heavier and with a factory addition I think you can then put on non-ai lenses. I have come so close many times getting an f100, if I could have found one like you, I would have gotten it just like you did. It's amazing to think that a wonderful camera such as yours basically sat on a shelf essentially since new......an amazing, amazing find.
I think the f100 also has better ergonomics as far as switches go also.
Plus I believe I can use the f5 as an attitude adjustment tool if the wife and/or kids get out of line.
Glad your happy with it....I know I would be too. I believe the D1 and the F5 are related as I recall an over simplification is that I thought I read somewhere the D1 was and F5 body with electronic guts.
I must say I do appreciate the light weight of my DSLR, but I rarely keep a camera on me all day. So I don't mind loading up one of my Nikons with all sorts of crap.....I especially feel good about life with a big Metz flash on any of my Nikons and a battery pack on my shoulder.....at least the P&S crowd know to keep quiet at gatherings unless they have a question!!
Here's a cool thing to try. In the custom setting menu, #4, set to "1" and #7, set to "1".
In the default position "0" for setting #4, a half push of the shutter button activates auto focus. When disabled, the AF button on the back becomes your focus activator. This allows you to focus then recompose and the shutter button won't try to refocus for you. A high tech version of manual focus.
This is a good idea. I have mine in default setup. Point to a subject and press the shutter half way. Re-compose.... then the camera often mistakes this to moving subject and refocuses. All 3 of my F100 does this. (my focus selector is set to S) It acts more like continuous focus than single focus. Very annoying. I'll have to try this.
Got out this morning and picked up a few rolls of HP5 from the Houston Camera Exchange. The first roll is in. I think I'm going to set up my beauty dish and Alien Bees and terrorize the dog for 36 exposures.
