For years I have been dreaming about getting Canon’s first super-telephoto zoom lens, the 200-400mm f/4 with 1.4x extender. This is the ultimate field sports and wildlife lens which can potentially replace two of my current lenses (or so I tell myself to justify the purchase). With a retail price of $11,799 I have thus far been reluctant to take the plunge. I have been on the look out for a good used copy since its introduction but almost nobody who has one of these bad boys is interesting in letting it go. When I happened on a sale for a new one that was below the current market price for a used one in excellent condition, I jumped at the deal. It is due to arrive on Wednesday and I am already starting to plan a few national park excursions to put it to good use.
