In this category you'll find auto winders and motor drives for automatic film advance with many 35mm SLR cameras. Plus, there'll occasionally be battery packs and other types of grip for AF or digital cameras. An auto winder is ideal for fast moving subjects such as sports, children and even portraits where you want to take another picture quickly as the subject changes expression. It also means you don't need to take the camera away from your eye to wind on – especially useful for people who use their left eye for viewing. Motor drives perform a similar function, but usually offer faster continuous shooting. Choose from the individual products below, with the latest additions and updates shown first.
