The Canon EF 85mm f/1.8 USM Medium Telephoto Lens is designed for Canon SLR cameras, offering a fixed 85mm focal length and a wide f/1.8 maximum aperture. This lens is highly practical for various applications, including portraiture, due to its ability to perform well in low-light conditions and create a shallow depth of field for artistic background blur. It features a Ring-type Ultrasonic Motor (USM) for fast, smooth, and quiet autofocus operation.
The lens is compact, measuring approximately 3 inches in diameter and 2.8 inches long, and weighs about 15 ounces. It is not a zoom lens, meaning the focal length is fixed at 85mm.

3.1 Focus Mode Switch
The lens features an AF/MF switch on its side. This switch allows you to select between autofocus (AF) and manual focus (MF) modes.
- AF (Mkazo otomatiki): For automatic focusing. The Ring-type USM ensures fast, smooth, and quiet AF action.
- MF (Mkazo wa Mwongozo): For manual focusing. Turn the focusing ring on the lens to adjust focus.
3.2 Aperture and Depth of Field
With a maximum aperture of f/1.8, this lens excels in low-light conditions, allowing more light to reach the camera sensor. The wide aperture also enables a shallow depth of field, which is ideal for isolating your subject from the background, creating a pleasing blur (bokeh). This characteristic makes it particularly suitable for portrait photography.
3.3 Fixed Focal Length
This is a fixed focal length (prime) lens at 85mm. It does not have a zoom function. To change your framing or perspective, you will need to physically move closer to or further from your subject.
3.4 Umbali wa Kiwango cha Chini cha Kuzingatia
The closest focusing distance for this lens is 2.8 feet (0.85 meters), allowing for relatively close-up shots while maintaining subject isolation.
