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.

I was amazed at how sharp this teleconverter is!! There is a slight lag in acquiring focus, but especially in good lighting it’s barely noticeable. Image quality is outstanding paired with the m.zuiko 300mm f/4 lens. I have used teleconverters on my full frame camera that didn’t come anywhere near the quality of this. Both images were shot handheld. My only regret is that I waited so long to purchase this.

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.

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.

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.

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