OLYMPUS OM SYSTEM MC-14 1.4X Teleconverter for the M40-150mm and 300mm f4.0 PRO Lenses (Black)

This is a great addition to the 40-150 f2.8 PRO lens.

Bought this tc1.4 to extend focal reach of my Olympus Lens 100-400mm to now 140-560mm. Works beautifully and enjoying it.

Great product. I have used on a number of occasions and feel the quality of image is great and the tele-converter well-built.

Crazy fast shipping (2 days) and product is perfect. Used for a trip to Australia to shoot wildlife and an equestrian competition, never took it off. Photos are super sharp and autofocus speed had no issues keeping up with running horses.

An excellent addition to the Olympus 40-150mm f/2.8 Pro lens (it also works with the 300mm f/4 Pro lens, but no others). Images remain quite sharp, and convert the zoom to a 56-210mm f/4 lens, an excellent solution for e.g. bird photography. (I haven't tried it with the 300mm f/4, which would be converted to a 420mm f/5.6). These are micro-4/3 focal lengths: on a full frame camera you'd need to double the focal length to get the equivalent field of view, at a corresponding penalty in system size, weight, and price. As an extra bonus when using the MC-14 with the zoom, near-macro shots can be taken (the smallest subject width at the long end is about 55mm, or 2.2"). In this near-macro mode, images are sharp and working distance is comfortable, but due to 210mm focal length the depth of field is very shallow. The MC-14 does double duty for near and far subjects at much smaller size and weight penalty than a second lens. On the negative side (reducing the score to 4 stars) is its relatively high price. It seems to be offered only separately in the U.S. although lens+teleconverter bundles could be attractive.
