Opteka OPTM3517O 35mm
The bright f/1.7 aperture and 9-blade diaphragm on this 35mm prime produce smooth background blur, aided by HD anti-reflection coatings and one ED element for controlled aberrations. Its compact 204g all-metal build and manual focus design offer a tactile, deliberate shooting experience at a budget-friendly price. This lens is best for Micro Four Thirds photographers learning manual focus portraiture or street photography who prioritize shallow depth of field over autofocus convenience.
