It’s a great review and the conclusion does back up the general agreement that a prime lens will always be sharper than a zoom, I guess we have to decide if the sacrifice is worth the versatility that the zoom will give.
One thing I would like to ask is about your shutter speeds, If these were all shot of a tripod with mirror lock up I guess it wouldn't matter so much, but you say shot 'hand held' and that could introduce an amount of blur depending on the shutter speed.
On this occasion it appears the results have been unaffected though.
