I've had two different customers come in to our shop int he last two days with the best whoppers I've ever heard about a camera. The first- the "associate" selling him the d40 told him his battery would not last more than 30 minutes without recharging, but that he could sell him a couple of battery packs that would last at least 2 hours...... The second- That the 70-300 USM IS they had was some special lens with "dual stabilizers". I'm aware of the dual mode that some IS units have, but this one was told that one was able to stop shake, and the other motion blurr. Do they not even TRY to train there associates. Beginner beware.....if it sounds stupid coming from a best buy, count on it being a sales pitch.
