Multi-coated lenses have several benefits in photography, including:

Improved Contrast: Multi-coating reduces the amount of light reflection and scattering in the lens, which results in better contrast and clearer images.

Reduced Flare: Flare occurs when light bounces off the lens elements and creates unwanted reflections in the image. Multi-coated lenses reduce the amount of flare, resulting in better image quality.

Increased Durability: Multi-coating makes the lens more resistant to scratches and damage from environmental factors such as dust, dirt, and moisture.

Better Color Accuracy: Multi-coating helps to maintain the true colors of the subject by minimizing the effect of unwanted color casts caused by light reflection.

Improved Light Transmission: Multi-coating allows more light to pass through the lens, resulting in brighter and sharper images.

Multi-coated lenses provide significant benefits that help to enhance the quality of images, reduce the need for post-processing, and increase the lifespan of the lens.
