Godfrey, this time I am thinking more about a reduced circle lens, such 
as Tamron 18-200, or 18-250 or even Sigma 18-200...

That Nikon lens - it did not appear bulky at all. It is of course less 
bulky that any 3-4 zoom lens solution that I have right now - 18-35, 43 
mm or 28-75/2.8, and 80-200 or 80-320. The last one is really bulky, by 
the way.

But I see your point.

I must also add that an idea of lossy compression of RAW files did not 
occur to me indeed. I find that impossible to imagine.
