Hi guys
Was just wondering for the same range of lenses of different make (eg Canon 24-70 f/2.8, Tamron 28-75 f/2.8, Sigma 24-70 f/2.8), why are the filter size, weight, etc different despite having the same f stop?
Was thinking of bring one of these lens for travelling and now, the Tamron lens seems to win hands down in terms of weight and size.
