Olympus teleconverter MC-14

Ideal for getting extra close to your subjects beyond your lens's capability. The MC-14's splashproof, dustproof and freezeproof all metal construction is compatible with the M.Zuiko ED 40-150mm f/2.8 PRO and the M.Zuiko ED 300mm f/4.0 PRO.By placing this teleconverter between the camera body and lens, you can increase the magnification of your subject up to 0.6× (equiv. 35mm) and extend the focal length by a factor of 1.4× (40% more reach). When coupled with the M.Zuiko ED 40-150mm f/2.8 PRO lens, a maximum focal length of 210mm (420mm equiv. 35mm) can be achieved. Macro shooting is possible at a working distance of 50 cm.When coupled with the M.Zuiko ED 300mm f/4.0 IS PRO lens, a maximum focal length of 420mm (840mm equiv. 35mm) is achieved.Please note: When using a 1.4× teleconverter, you lose 1 stop of light, so for example, when using an f/2.8 lens, the widest aperture you can use the lens at is f/4.0.
