The Canon IS are not very popular. Serious birdies tend to go for Swarovski, the most popular, then Leica. I tested loads of pairs and found that the Hawke Frontier ED 8x43 performed as well as the Swarovski at about 20% of the price. Quite remarkable for a company whose other products were not noteworthy - they got it right for this model.
