hedwards: OTOH, the dragon fly picture earlier in the thread isn't one that I could have taken with my big camera, I just couldn't have gotten close enough.
Reveenka: I'm sure the equipment met your needs at some point, otherwise you probably wouldn't have gotten it. Are you looking to replace it now, though? If you like macro there are some really good lenses to choose between, but you'll still need that tripod.
If not macro, then the 85mm and 135mm would be excellent replacements. If you need a higher focal length, the 200mm is also pretty darn good, and both more compact and cheaper than the 70-200.
I'll be going back to my old equipment some day, and possibly throwing on a TC, right now I just needed something with reach that I could carry around with me. I ended up with the Canon Powershot SX40HS. Which is quite impressive for a P&S.
It's more a matter of having to live out of a suitcase and small backpack these days and not having physical space for all the gear. I ended up trading quality for a tremendous amount of flexibility.
hedwards: But, regardless of the lens I'm using I pretty much always use some sort of support because it makes the images that much more sharp and IS doesn't solve that problem.
Reveenka: I usually try to not use either (tripods because I can't run around with them - IS because it belongs to higher focal lengths) as my job requires me to be extremely flexible, and so far that has worked fine. I'm usually smack dab in the middle of whatever's going on, so if my wide-open wideangles can't do the job on their own, I have my trusty flash to help me out.
Learning how to use a flash properly is something everyone who owns one should learn. Most people use it to light up scenes that are too dark, but they're really meant to even out the lighting so you aren't stuck with really hard shadows and a contrast you can't even fix in Photoshop.
There are easy ways to remedy the "all the people in my photos look like deers in headlight"-situation. ;)
EDIT:
Also, Zeiss is fantastic, hands down. You have to not mind manual focus, but it's easy to get used to. Don't let that scare you off from Zeiss lenses.
I really should get an external flash. One of the nice things about this particular camera is that it has a hotshoe. It also happens to have a decent meter with interactive histogram. And when I use the Canon Hack Development Kit, it will show me when I'm composing what highlights have been blown.
overread: hedwards - have you considered looking at the new micro 4/3rds "hybrid" cameras? The likes of the Olympus EP series or OMD series or the Panasonic G1series give you a smaller camera, smaller sensor, but with the similar controls as a DSLR. They even include interchangable lenses and the Olympus OMD and Panasonic G1 series have viewfinders (electronic, but still viewfinder positions); whilst the EP series has a slip on attachment (you lose the hotshoe though).
4/3 was one of those things where I'd like to know what precisely they were thinking when they came up with that monstrosity. You get all of the disadvantages of a proper dSLR with the small sensor size of a P&S camera. Plus, I don't think you even get the option of professional glass either.
I'm sure there's a market for it, but then again, those people would be happy enough with a so called ZLR or bridge camera with proper controls.
overread: I've my eye on getting one for when I want a lighter, smaller and more portable camera - esp because the crop factor means that I can pack a light 70-300mm or even 70-200mm type lens and get an angle of view around double those focal lengths. Great for wildlife and similar situation grabshots which, with a DSLR simply requires my to carry way too much for a light trip or when doing things other than photography.
That's why I got my new camera late last year. It's light and features a damn long lens, it's not a real 840mm lens, but if you can ignore that, you can get some tight shots.
