Bower SLY1620OD
Its f/2.0 maximum aperture and 13-element optical design with two aspherical lenses deliver sharp images with controlled aberrations on the Four Thirds system. The 32mm equivalent focal length and multi-coated optics provide a natural perspective with reduced ghosting, making it a solid manual-focus prime for its class. This lens is best for portrait and close-up photographers on the Four Thirds mount who prioritize a fast aperture and precise manual control over autofocus convenience.
