1. Pwodwi souview

Its compact design is achieved through five zoom groups, resulting in a length of only 4.8 inches (121.5mm). The lens features a rear focusing system, which ensures that the lens length does not change and the front element does not rotate during focusing. This design maintains the integrity of any attached filters and contributes to quick and quiet autofocusing.

Focusing Modes (AF/MF):

This lens supports both autofocus (AF) and manual focus (MF). A switch on the side of the lens allows you to select the desired mode.

• AF (Otofokus): Set the switch to 'AF'. The camera will automatically focus when the shutter button is pressed halfway. The Ring-type USM provides fast and quiet autofocus performance.
• MF (Fokus Manyèl): Set the switch to 'MF'. Rotate the focusing ring on the lens to adjust focus manually. This lens also features full-time manual focus, allowing you to fine-tune focus manually even when in AF mode, without needing to switch modes.

Zoom:

To change the focal length, rotate the zoom ring on the lens. The lens offers a zoom range from 100mm (wide telephoto) to 300mm (super telephoto). The current focal length is indicated on the lens barrel.

Kontwòl Ouverture:

The aperture (f/4.5-5.6) is controlled electronically by the camera. Select your desired shooting mode (e.g., Aperture-priority AE, Manual) on your camera to adjust the aperture setting.

Sèvi ak filtè:

The front of the lens is threaded to accept screw-in filters. Since the lens uses a rear focusing system, the front element does not rotate during focusing, which is beneficial when using polarizing or graduated neutral density filters.
