I understand where you are coming from
lets look at it from the dollar perspective then. We can take the 70-200mm f4 as the benchmark so the L-glass will cost about S$1300. Typically IS will command another S$400-S$800 so we take the average at S$600. Therefore, you will get 1300 + 600 = S$1900 of tangible benefits and another S$200+ worth of intangible benefits like its uniqueness (since we dont have choice wat, who ask you to choose Canon!?), then the price is almost there already liao
