Why not just give it a try with the old tripod first?
Do you have a legs/head combo, or are legs and head separate? I'd be cautious about using a light camera on a head that's designed for much heavier gear, so your 5 pounds on a head designed for 6.5 pounds may work out better than the same camera on a heavy-duty head made for a 20lbs camera. That is, assuming the legs are heavy and sturdy enough to hold everything in place.

I have a Sony Lightweight Tripod (http://www.sonystyle.com/webapp/wcs...151&langId=-1&productId=11037227&tab=Features).
I just don't think it's sturdy enough. It's never given me problems in the past... but I just don't know.
I have exactly that tripod and it works fine with my Z1, I wouldn't want to use anything heavier on it though...

As far as sturdyness goes, you are of course correct. However, good tripod heads have a counter-weight (usually through a spring in the head) that stabilizes the camera as it is being tilted, and that spring or counter-weight must match the camera weidht to work well. Good tripod heads have an adjustable counter-weight, but only within a certain range. This is where it can hurt to have a head that's designed for a heavier load than what you actually mount on it.That makes no sense. Something designed for heavier camera have havier duty components. Someting with max capacity of 20 pounds can support 0 to 20 pounds, and will be more sturdy than something with max capacity of 6 pounds.
