In the past, many professional photographers have shied away from auto-focus cameras, complaining that the slow speed of the auto-focus let valuable shots slip away. Quite often it was simply quicker, not to mention more reliable, to focus manually. The H1, however, offers lightning fast, super-accurate focusing under almost any conditions, guaranteeing that even the most fleeting of instants can be frozen accurately and clearly. And the auto-focus features an instant override function, enabling easy access to manual focusing without leaving the auto-focus mode.The H1's central lens shutter design enables virtually vibration-free exposures at even the longest shutter speeds and makes the H1 capable of flash-synchronization at all shutter speeds, up to 1/800 of a second.The advanced auto functions of the H1 take the guesswork out of your photography, allowing even the most spontaneous of shots to be perfectly focused and exposed. In addition, the H1 can be customized to suit your individual needs. The H1 allows you to save specific setting groups as so called profiles so you can then instantly access a whole range of pre-determined options at a press of a button. This extremely useful feature enables the H1 to adapt to your specific work method or style, not the other way around. But even when changing settings manually, the H1's ergonomic design and intuitive user interface enable you to make fast, easy adjustments without removing your eye from the viewfinder
