>Moral; If top quality "optics" isn't your priority, you don't need the manufacturers best lenses.

True, but your lenses are not bad either. I would recommend your lens kit (except I don't know the Tamron 90mm) to anyone who looks at weight and tighter budget. Actually I would love the 70-200mm f/4 if it had IS.

The new 70-300 DO IS lens could be my travel kit lens.

Again, you have to know yourself.

I wanted to explain why having lenses from Canon/Nikon may not mean too much (as in my case).
