OM System OLYMPUS M.Zuiko Digital MC-20, 2X Teleconverter

I added this to my OLYMPUS OM-D E-M1X and OLYMPUS 150-400MM F/4.5 TC 1.25 IS PRO LENS, which gives me the equivalent of 2000mm, handheld. The clarity of my photos is amazing, especially on the feather detail in bird photos taken at about 30 ft. It is terrific for photographing birds 100-200 ft. distant. I even use it to identify distant birds that are beyond the range of my 10X binoculars. Although there may be a slight speed reduction, it is not significant. I thought at first that I would have to take it off if I wanted to shoot photos at 150 mm, but I found the only ones I couldn't focus on were birds less than about 10 ft. from me, so it is simpler just to leave it connected always. I do find that I need to use my zoom much more than previously, in order to find the bird at lower magnification and then zoom into it at highest magnification.

It works brilliantly with both the 40-150mm f2.8 and 300mm f4 Pro lenses, providing clarity and contrast at near native-lens levels. Obviously there is a loss of light (putting the lenses maximum aperture to f5.6 and f8 respectively) and an accompanying slight loss in autofocus speed and accuracy, but this is an impressive little piece of glass. Anyone familiar with the MC14 1.4x teleconverter will be right at home with this. A word of caution: the 300/4 lens becomes a 600mm lens with this, or 1200mm in full-frame camera terms. If you have not used a lens in this range before, it takes a lot of adjustment to being able to find your subject. The field of view is so narrow that significant practice is necessary to be able to sight your target. But I did get a picture of Jupiter this evening with bands of cloud and the great red spot visible... handheld.

Took a bit to get the settings just so, but worked nicely with 300F4pro lens for either stills or using the pro capture mode on an Olympus OM1 four thirds micro frame. With the teleconverter the enlargement is the same as 1200mm with a full frame. For the flying trumpeter swans they nearly filled the frame, but images were still sharp.

I have the 1.4 and got the 2.0 for big reach with 40-150, 300mm, and 150-600. Of course it is not as sharp as the 1.4, but sometimes you just need big reach. Videos look pretty good which is what I mostly shoot, photos a little soft, but we're talking about monster reach.

I have paired this with the 300 f/4 pro and the OM-D E-M1 iii exclusively this far but also have the 40-150 f/2.8 to use with it. The build quality is Olympus pro quality and the image quality is incredible. It does limit you to f/8 with the 300, but the bokeh and background separation are still excellent. The images are crisp and I have not noticed any image quality degradation, which is stunning, but hear it can occur with images very far off in the distance (mostly atmospheric influences I suspect). Comparatively, in my opinion better quality than cropping. I have no problems hand holding and even shoot at shutter speeds as low as 1/200 with this combo. It even works well with HHHR. All in all, definitely worth the cost and even more so when compared to the 1.4x which I also own. If you want more samples check GreinerStudio on facebook.

The part sticking out of the front is quite fat and does not fit any of my telephoto lenses. Specifically the Panasonic 45 - 200 mm which I purchased it for. The listing mentions the M.Zuiko Digital ED 40-150mm F2.8 PRO and M.Zuiko Digital ED 300mm F4.0 IS PRO so if you don't have one of those you will probably be disappointed and have to return it like I did.

The questions that must be entered to get to this point may not be applicable since this is Teleconverter. I use it on a Olympus Pen 8 MT (100-400mm) Lens . It is a precision fit. The images of a hawks nest with youngsters was very sharp. The 100-400mm lens was adequate but using the Teleconverter made the original better for enlarging the image to an 8x10. The image was very sharp.. I would buy again. It is expensive but worth the money. I am an experienced photographer but I just judge a product by "did it do what I wanted". The answer is yes.

Excelente teleconvertidor. Usado para fotografiar deportes y vida silvestre.

A very good product. It works well with my new 40-150mm f2.8 Zuiko lens. Can't fault it or the service I received from the seller.

Excellent, looks good and fits perfectly! Recommended for extending the reach of your Oly zoom. Only works on 40-150m and 300mm. Sharp results. Use it more often than the MC 14.

I use compatible lenses, happy to get it then the price went down 41% the next day 600 to 400.... Pissed off, don't pay more than 450. With the right lenses it's a good product.

This 2x teleconverter is a lightweight solution to extend the reach of Olympus 100-400mm to 200-800mm. However, I used it only when lighting is good and the subject is beyond the reach of 400mm, as the largest aperture becomes f13. Focusing is still quite fast and accurate on EM1 mkii which I am using, even in indoor lighting.
