'I've seen reviews of the f/2.8 'pro-spec' lenses from Olympus and Panasonic that claim, in terms of image quality, they are somewhat similar to other slower zooms and suffer in comparison with primes. I'll be discussing that in more depth in a later article, but in terms of the Olympus m.Zuiko 7-14mm f/2.8, I don't think thats true at all. In fact, I think it's a rather good lens.'
