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

Excellent value, OM system rocks!

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.

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.

This is a well made TC, tops in fit and function and let me tell you, used with my Oly. E-M1 and 40-150mm f2.8 PRO lens, is as sharp and crisp as you're gunna get! "Tack Sharp from center to all 4 corners!" If it scopes out as good with the New-Up and coming soon, Oly. 300mm f4 PRO, I will have a double hitter! Expensive, YES! But so is all my Nikon gear, and is my wife of 48 years!! Just get one, it is a keeper that you will not regret! Oh, by the way, the MC-14 1.4 will only work with the Olympus 40-150 f2.8 PRO and the New Olympus 300mm f4 PRO lenses, to date! At 1.4X the 40-150 becomes a 56-210 and @ the 2X 35mm crop factor, it is a 112-420mm. The 300mm at 1.4X becomes a 420 and @ the 2X 35mm crop factor, it is a 840mm!!! If all holds true to form as Olympus has, and everything stays sharp, crisp and true to color, what else can I say? :-) The two shots were taken at sundown with my E-M1, MC-14 and Oly 40-150mm f2.8 (f4) same subject at 150 yards and zoom set at 56mm, 1/125, ISO 250 and at 210mm, 1/250, ISO 1250! Both hand held with 5 axis stabilization on etc... R/ The PhotogDog
