Manual focus in cameras has changed the way photographers visualize and play with their creativity.  
Uses of Manual Focus Lens
The best manual focus lenses in the market are usually those that have a variety of options of features so that you can adapt to every environment with ease. Keeping in mind the following points that describe the uses of a manual focus camera:
Aperture 
Aperture, which is simply the amount of light that passes through your lens and is expressed in f-numbers (f/3, f/6, and so on). On your manual focus slr lens, you can twist the dial to either allow or restrict the light from passing through. Through this, you can even adjust your depth of field to deliver sharp or blurred images. 
MF lenses help you alter the image as per your preference. Especially when the lighting conditions are bleak, this feature helps you create the perfect conditions to capture the shot. 
Depth of Field
The depth of field helps you to adjust the focal length to give you your desired look. A thin depth of field helps you achieve a shallow focus look that keeps the subject in focus while blurring the background. A large aperture makes this possible. 
On the other hand, a deep depth of field will help you capture sharp and defined images that show the true image. Keeping your aperture small will ensure that this can be achieved with ease. When you want your subject in focus, you can use your manual focus DSLR to adjust accordingly and vice-versa.
Street Photography
Most manual focus camera’s come with a preset setting so that when you want to go out and capture pictures on the street, you don’t even have to look into the viewfinder to adjust the settings. When you want to explore this kind of photography, it is often important to be able to capture moments without worrying about the lighting or the depth of field. This is where a manual focus lens comes in handy.
While it is not for everyone, but in a professional setting, knowing the usage of a manual focus DSLR is important.
Manual lenses help the photographer customize their product while capturing it. It is used to save time in editing while experimenting with different ways a shot can be taken.
