Thanks David. I must admit I had discounted the 14-54 as a potential purchase since I assumed the 12-60 was the way forward. I'd also read many people who talked about bad iq and had to send the 14-54 lens back to Oly. Having done more research I think it is safe to assume that both lenses are excellent but that the 12-60 is slightly better. Whether the 'slightly' justifies an extra Ł300 is the bit I'm struggling with
