The successor to the EOS-1 and the new top-of-the-line EOS camera. With a cross-type BASIS for the AF sensor, the camera offers five focusing points which can be selected automatically or manually. The wide focusing area makes it easier to focus track moving subjects in the predictive AI Servo AF mode. The camera matches well with super telephoto lenses having a built-in USM (Ultrasonic Motor) for silent and fast operation. Exposures can be compensated in 1/2-stop or 1/3-stop increments for higher precision. The EOS-1N is highly rated by pro photographers. Very reliable and durable with a lifespan of 100,000 shutter cycles. The mechanical operation has also been refined for silent operation.
