Prime Lenses
Prime lenses are typically sharper, lighter, and can work in lower lighting conditions than zoom lenses.
Less compromises are involved when a lens can be designed for optimal performance for a specific focal length.
They don't have to overcome all of the additional problems encountered with the extra glass and mechanics required to zoom.
With their typically faster (wider) maximum apertures and fewer lens elements, primes can also gather and pass through more light.
As a result, even in poor lighting conditions, you can generally get better quality images and videos.
Additionally, due to their smaller size and weight, they are perfect for travel, and stealthy street shooting.
