Is the Canon 5d (original) a worthy upgrade to the Canon 50d? I mean can I expect a major improvement in DOF for portrait type shots and ISO performance? The 50d has a larger screen, weather sealing, live view and microadjustment; so is the later really worth it? Lasty, what program is used to check the shutter count on a 5d?
You cannot check the shutter on the 5D. Just estimations.
The 5D is definitely a nicer overall image producer in ISO, image quality, depth of field control, over the 50D for portraiture. The 50D is better for autofocus, burst shooting, etc, so it's more of an action camera, better suited for wildlife, sports, general shooting, etc. The 5D gives you a bit more edge for portrait specifically. It's a great way to get a taste of what full frame is like without going `all in' budget wise.
I shoot a 5D classic exclusively these days for portrait. I don't look at the LCD screen for anything other than the histogram. You can't tell if something is sharp or not on that screen, it's pathetic, definitely not a strong point. It has no live view, so you can't use that for anything useful. It's AF system is not robust, pretty basic, and it's center point while good, is it's only really useful AF point. The other points are pretty weak in my experience. But I shoot my 5D with manual lenses more often than with autofocus, because I'm simply better and more comfortable with manual focus while composing portraits (I don't have to focus, recompose). I use a precision matte screen EE-S with mine, so I focus via depth of field really, so it's easy as pie. I can focus in the dark with a wee bit of light really (so I can focus right through 6 stops of ND filters which I commonly do with this thing as I like shooting F1.4 in the bright sun with flash for some of my portrait work). The ISO grain of the 5D is more pleasing to me too, it has a film look. It's color and tones are also more pleasing to me. You don't get the 5D for advanced features.
When you look at a 5D today, you look at it as a great way to get a film-like ISO digital camera that is full frame, with tight depth of field control, precision matte screen capability for precision manual focus use. You do not get the 5D today for it's autofocus ability, it's LCD, it's resolution, or any other feature along those lines. It's why it's a portrait camera to me. Or a general walk around camera.
I use a more modern APS-C (several actually) for the non-portrait stuff.
