#3. "RE: D40 battery grips?" In response to Reply # 2
I don't know anything about the battery grip you're referring to, but I would strongly urge you to rethink whether you really want a battery grip for the D40.
1. It sort of defeats the purpose of this purposefully small, light, camera, doesn't it? 2. The battery life of the D40 battery is excellent by all accounts, so if you must, just by an extra battery. 3. With a camera this small a vertical grip is not really necessary, even for the smallest hands. 4. Finally, I can tell you from experience that third party battery grips are generally poorly made with serious fit and compatibility problems. For the vertical shutter release to operate, they usually require some sort of infrared connection to the AF illuminator, because the electronics will not synch with Nikon's proprietary system. Thus you lose the use of the AF illuminator which can be a serious loss because this camera is such a terrific lowlight performer.
