Olympus MC-20 M.Zuiko Digital 2X Teleconverter

I pair this teleconverter with the Olympus 100-400/5-6.3 lens, and I get good results. You have to be aware that atmospheric haze/distortions come into play when your subject is far away, so set you expectations accordingly. I find that I really like using it to make small, close subjects larger(macro/semi-macro shots). All three pics on this review were shot with the OM-1, 100-400, and MC-20.Moon800mm, f/13, 1/2000th sec, iso 1600Caterpillar800mm, f/13, 1/640th sec, iso 800Blackbird800mm, f/13, 1/1000th sec, iso 800

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.

Works well with the 300mm f4.0 and the 70 to 140mm f2.8 zoom.

Received in good shape. Got couple of decent photos of wildlife.

Any converter adds a step to setting up, lowers the light coming in, exposes the camera body to one more chance of collecting dust inside. This one is no exception, but it does a very good job in maintaining the quality of the lens you attach it to.I bought it to wait for the next large zoom coming out, but at over 7k for that zoom I might be happy with this setup ( I use it with my 300mm fixed and my 40-150mm zoom) for quite a while longer.

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.

Like new! Worked . . . BUT MUST FIRST Update camera firmware!!

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.
