Query: Excellent, but 72mm filters not 77

I chose this lens over the costlier/heavier 70-200mm f.8 L zoom due to the fact this it is roughly one third the weight and one third the cost of the zoom.So far I'm very pleased with the lens and for my purposes I don't miss the zoom option. My only complaint is that the lens takes a 72 inch filter, rather than the 77 inch filter which I had read was standard across the L family lenses. I'm posting this review to point this out to others who might have the same wrong impression.
