Tripod advice

But what sort of non light demands 1/30s wide open WITH flash?

Sorry i just don't get people who want to put modern DSLRs with amazing iso performance and image stabilisation and all that on tripods.

I only really shoot primes and with a little practice i'm now able to hand hold down to a shutter speed about half my focal length and get pin sharp results. And thats without IS.

If I wanted sharp pictures with flat depth of field, I'd get a compact.
It's just not my style.
Apart from that, it depends what I need and what lens I'm using. And I tend to avoid flash, if it's not needed.
