Glossary Of Photography Terms [1]

Slow Lens In photography, a "slow lens" refers to a lens with a relatively small maximum aperture, which limits its ability to gather light and control depth of field compared to lenses with larger maximum apertures. Slow lenses are typically characterized by higher f-stop numbers, such as f/3.5, f/5.6, or higher, indicating smaller maximum apertures.
The smaller maximum aperture of a slow lens restricts the amount of light that can pass through the lens to the camera's image sensor, requiring longer exposure times to achieve proper exposure in low-light conditions. This can result in slower shutter speeds, increased risk of motion blur, and the need for higher ISO sensitivity settings to compensate for reduced light-gathering capability.

While slow lenses may have limitations in low-light situations and may not offer the same degree of control over depth of field as faster lenses, they are often more compact, lightweight, and affordable, making them popular choices for casual photographers, beginners, and photographers on a budget.
Photographers using slow lenses may need to employ techniques such as image stabilization, tripod usage, or external lighting to overcome the challenges associated with slower apertures and achieve optimal image quality in various shooting conditions.
