OM System M.Zuiko Digital ED 12-40mm f/2.8 PRO II - Micro Four Thirds Mount

The OM System M.Zuiko Digital ED 12-40mm f/2.8 PRO II is an updated version of the classic professional standard zoom. It features a constant f/2.8 aperture throughout the 24-80mm equivalent range and carries an improved IP53 weather-resistance rating. The optical design includes advanced coatings to further reduce ghosting and flare, maintaining excellent sharpness from corner to corner. Check the manual focus clutch mechanism by sliding the focus ring back and forth to ensure it engages correctly. SDS inspects the zoom action for any gritty feeling or uneven resistance. The front element should be clear of scratches, and the metal barrel should be checked for impact marks. Ensure the weather sealing at the mount is pliable and undamaged, as this is a key feature of the PRO II designation.
