File format
Do you find that you capture all photos as RAW and then when putting them on your PC you then process them all to JPG? Do you even convert them to JPG or just leave them RAW? Or do you instead find for the majority of pics you just capture them in JPG on the camera and shove them straight onto the PC unprocessed?

Anti-Shake
I'm trying to work out how useful the anti-shake built into cameras such as the A100 is. If I was to connect say a Sigma 70-300 APO Macro lens to a camera like a Nikon D80 (without a tripod etc), how much would it suffer from not having anti-shake for typical outdoor shooting?

it is easier to process from RAW rather than jpg and its harder to share with raw then jpeg due to size mainly and not many photo hosting taking raw pictures anyway.

image stbilization is better if its on the lens the A100 may not be effective thoughout all focal lengths. Generally the sigma lens is good but not as good as the lenses with IS, weather it be Sigma, nikon, canon etc..

But how important is IS on general hand-held day light photography? If you're using the longer reaches of that 70-300 lens (standard or Macro) hand-held, is it going to be OK, or is IS basically a must?
 
As far as IS goes then, there are two different paths then:-
1) Say an A100 with something like the Sigma 70-300 APO Macro lense.
2) A D80 with the 50-200mm VR DX lens, or the 70-300 VR ED lense.

The thing is of course you could get the A100 with the kit lens and a Sigma 70-300 APO for less money that the D80 with its 18-70mm kit lens, yet alone start talking about (for the Nikon) another £150 for the DX, or £300 for the ED telephoto lenses!

Likewise the Olympus 510 with its kit lenses (14-40 & 40-150) work out about the same as the D80 with just its 18-70mm lens!

I suppose being new to all this I'm wondering how much I have to be consider IS. I mean if I extended to the D80 with the 17-70mm lens and later wanted to put on the Sigma 70-300 APO Macro, is that a usable lense with that camera without IS/tripod (say upto 200mm)?

& IS built into the lens has a startup time (usually ~.75s) that in-body doesn't have & the extra optical elements often degrade image quality compared to the non-IS version.

At the end of the day they are 2 different solutions to the same problem, both work but have different pros & cons - & you are better with either than without if you frequently use long lenses or shoot in low light.

Well the Nikon 18-200 VR seems to produce nice quality pics :)
