I just purchased a Canon SX260 HS, and I've been researching AC adapters for it (Canon's model ACK-DC40, or equivalent, to be specific). It appears (confirmed by a lengthy discussion with Canon tech support), that the camera battery must be removed and replaced with the DC coupler included in the AC adapter kit. This is the only way that you can actually plug the power supply into the camera - there's actually no input plug on the camera itself. It also appears that this is Canon's preferred method for many (if not all) of their camera models.
I find this extremely inconvenient. It means that when I transfer images to my computer, or view them with my TV (things I would prefer to do without depleting the battery), I lose the ability to set my camera upright on a flat surface, or on some tripods. Not to mention unnecessary wear and tear on the flimsy battery door and rubber cover.
I like the camera, but I doubt that I would have purchased it had I known this (yeah, I know, my fault for not researching the AC adapter in advance, but who does that?). I own Olympus and Panasonic digital cameras (along with their associated AC adapters), and they do not require removal of the battery (although I wish they would allow in-camera battery charging).
Is it just me, or do others question the rationale for this design? I'd have returned the camera by now (it's still within the store's return period) but for the fact that after many weeks of looking at reviews and reading specs, I haven't found a replacement that performs as well.
OK, end of rant. Sorry to have taken your time.
