It's a bit more complicated than that...
I bought the 320mm zoom yesterday. It's a bit plastic, but seems solidly built and to be giving sharp results. @User has also kindly lent me his mirror lens, which is giving gobsmacking close-ups.
Unfortunately this laptop seems to be moaning when I ask it to read SD cards, so I'll have to try again with a different PC.
