Review: Love this - Excellent value, OM system rocks!
Review: An excellent companion to Olympus 40-150mm f/2.8 or 300mm f/4 Pro lenses - 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.

## Questions & Answers

**Q: Would this work with a Zuiko 4/3 50-200mm 2.8-3.5 WITH a 4/3 to M4/3 adapter? (on a M4/3 camera)**
A: No, this converter is designed to work with two lenses, the 40-150 pro f2,8 and the yet to be released 300 f4

**Q: its works for olympus digital 40-150?**
A: Hello Marco, the MC-14 will work with the Olympus 40-150mm f/2.8, but not with the Olympus 40-150mm f/4-5.6.  The MC-14 also works with the Olympus 300mm f/4.0.I use the MC-14 with the Olympus 40-150mm f/2.8 and am very pleased with the results.  All the best.

**Q: Would this lens work with the m. zuiko ed 12-40 mm f2.8 pro lens?**
A: No, it does not work with the 12-40mm. I have both, and this teleconverter protrudes into the lens and is only compatible with lenses with a recessed rear element. On the 12-40mm, the rear element is flush with the lens mount, and the teleconverter cannot be attached. It will work with the 40-150mm PRO and the new 300mm PRO. I've also used it with an old Nikon 300mm with an adapter, and it may work with some other lenses not acknowledged by Olympus. But be careful, you don't want to damage your lens.Note, the other replies are referring to a different teleconverter from the one shown here, made for a different mount.

**Q: Does this come with a manufacturer’s warranty?**
A: I believe it is one year if purchased new from an authorized vendor.  It can be extended four years if your purchase an extended warranty within the original warranty period. If you are in the US, I have heard that products purchased from international vendors may come with a warranty but may be difficult to enforce if a problem develops.

### ⭐⭐⭐⭐⭐ Want the best TC to go with the best lenses ever (40-150mm f2.8 and 300mm f4 Pro's) "Get the MC14 1.4X
*by P***G on March 27, 2015*

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
