High-Speed, High-Precision Autofocus

Thanks to a newly developed TTL phase-contrast detection system , the E-1 is able to perform high-speed, high-precision auto focus under a wide range of conditions from 0EV to 19EV (with ISO 100).

If insufficient light is available, you can light the AF illuminator. You can also choose whether to use release-priority AF or focus-priority AF. To focus on moving subjects, the continuous AF estimates the subject’s next position. The camera automatically selects the most suitable focusing area from the three areas, or you can select the focusing area manually.

Focus can also be locked when necessary by pressing down the shutter button halfway or by pressing the AE lock button (when the function has been changed from AE lock to AF lock).

Of course, a focus ring is also provided for manual focus, as well as for manually fine-tuning focus after auto focus is complete. You can set the focus ring’s rotation direction to right or left as you prefer.
