Im looking for a camera / lens that i could go out to use in a bunch of different scenarios like birding, low light photography especially in places like a club setting, or the sky/astrophotography to the extent where a long exposure to see the wide sky.

I've been eyeing the X2D2 as a potential BIFL, but was wondering if it would would work specifically in the setting of birding where things need to be quick, problem is that I see the lens catalogue doesn't quite have a calibre of zoom lens that I would be looking for.

So my question is this, is the X2D2 and the lens options that it has enough to satisfy what im trying to get out of it?
