Honeywell settled patent infringement cases with seven camera makers that it had accused of using its patented technology for autofocus lenses.

The F series were autofocus lenses.

Moreover, autofocus lenses have the annoying habit of frequently being confused by the aquarium glass, resulting in out of focus photographs.

The autofocus lenses contained a motor, and electrical contacts in the lens mount connected this motor to the camera's circuits.

These autofocus lenses were rather heavy and depended upon their own large, lens-mounted motors.

The new camera has three megapixels for an improvement in detail and color accuracy, as well as an autofocus lens for much-improved sharpness.

The 35 mm-70 mm AF Zoom was not the first autofocus lens of any kind to reach consumers.

It was the first camera in Canon's new EOS series, which was designed from scratch to support autofocus lenses.

Hasselblad moved away from the traditional 6x6 format to 6x4.5 cm, and included autofocus lenses.

The main disadavantage of using adapted lenses however, is that focus is manual even with natively autofocus lenses.
