Pros:

Jack of all traits , Master of NONE, what I meant is it can be mounted to Sony , Canon ,and Nikon

Open aperture of 1.4, you can capture photos focusing on your subject at a much more desirable degree

Splash and Dust proof, making it almost maintenance free

Cons:

You can’t zoom and zoom out from your subjects , it will be constantly be at 105mm unlike other lenses that could go from 18mm to 200mm

You’ll have to be as far away from your subject as possible to fit them inside the frame causing other variables to pass inbetween of you and your subject when shooting in an open crowded place
