Hi, I am looking for a L Series lens for my Canon... the one which seems to fit my budget is this one:
Canon EF 100-400mm f4.5-5.6L IS USM http://www.amazon.com/Canon-100-400mm-f4-5-5-6L-Telephoto-Cameras/dp/B00007GQLS/ any first hand opinions ?... is this significantly better than a good Sigma lens ? ashok
