I bought Pentax's cameras. AA batteries are one of the important reasons ! I hate to bring serveral chargers for the same make of cameras. IT is NOT earth friendly and is just another trick to make money. Canon, Nikon, Olympus, Panasonic have "dozens" of batteries which are totally imcompatible with each other. Are such batteries technologicial better ?? Of course NOT ! Pentax is the only of the few companies using AA batteries as a standard option . They should be proud of their contribution to protect the earth. Not only the performace is better, it does good to our luggage (without some proprietary chargers!!) I suggest the consumer protection should look into this matter seriouly ! I see no point in having different batteris for Canon 5D series. It is a scam.....Pentax does a great job and should keep it up !
Loren3: I'd like to see it compared to the SX20 (which I own) and the 30, in IQ and dimension. The SX20 is the max size I'm willing to carry for mountaineering, but its IQ outside bright light is not acceptable to me.
Why didn't Canon use the energizer ? It gives the users only inconvenience and nothing else. Should you carry a charger with extra battery ? No, get one which you can use the most available battery and forget Canon !
