Blimey Rob - do you work shifts or something? Yes, your right about primes, it's an odd feeling again. Do you know, I'm seriously thinking about buying a 14-54 f2.8 tomorrow to complement the Sigma. I'd made up my mind that the 12-60 was the way forward but the older lens is half the price and from what I can gather is not that much different. I'll be bloody glad when this next weekend is over
