Pros: Quality, Weight & Size

Cons: It costs less than the competition, but still a lot

Opinion: For a 2x (top quality) it's pretty small and light. The main issue is that there are only two lenses in the entire Olympus/Omsystem lens range that can afford to mount it, namely the 300 Pro and the 40-150 2.8 Pro. All the other compatible lenses, which are few (150-400, 150-600 and 100-400) do not hold it, and lose sharpness in a very conspicuous way, in practice the 2x on these lenses is totally useless. Even the 150-400 doesn't hold it. If you own one of these three telephoto lenses, avoid spending 350 euros, it will be money totally thrown in the bin. To photograph distant birds it is absolutely useless, it damages the quality in a conspicuous way and makes the autofocus lose a lot of precision. It's always best to use smooth lenses and then crop. Conversely, if you own the 40-150 2.8 you will be able to use this 2x with satisfaction, the optical quality remains high, excellent closing to F7.1 and the autofocus remains very fast, even if it loses a bit of precision in very dynamic situations. Same goes for the 300 Pro.. the quality remains excellent at full aperture, there is just a slight tarnishing of the quality at full aperture and some slight aberration, while at F10 everything is fantastic again. Unfortunately, however, the continuous autofocus loses a lot of precision and becomes practically unusable for birds in flight. No problem for perched birds and wildlife. The stabilization of the lenses remains phenomenal, as if they were smooth.

Pros: Quality construction - Economical compared to 2x teleconverters of other brands (Nikon/Canon/Sony)

Cons: Nobody

Opinion: I have been using this teleconverter on various Olympus telephoto lenses for a year and I must say that it gratifies me more than the 1.4x (MC-14). In some ways the photographic yield is even better mostly when used on the top-of-the-range M.Zuiko 150-400mm f/4.5 tele. Precisely on this lens the 2x can be combined with or without the built-in 1.25x teleconverter reaching double focal lengths, from 300 to 1000mm (600mm and 2,000mm if we compare it to full frame). The photographic results are excellent and sometimes it is surprising to see the sharpness with the 2x combined with an OM-1. Used on other lenses such as the 40-150 f/2.8 or on the 300 f/4 the MC-20 teleconverter returns excellent photos. Suffering if combined with the M.Zuiko 100-400 especially at the maximum focal length (400mm f / 6.3) which becomes an 800mm f / 13 (with the 100-400 is to be used only in case of emergency on very distant subjects). Highly recommended in the m4/3 field for those who do nature photography and use M.Zuiko telephoto lenses.

Pros: Well built, small, tropicalized

Cons: Nothing except that I had to update the 40-150 f2.8 on which I intended to use it

Opinion: Now with a contained expense (I found an excellent opportunity) I find myself with a 160-600 mm f 5.6 equivalent, of small size and weight, high image quality, fast autofocus, sometimes undecided but nothing serious for me I went a little beyond the weights and dimensions to which I was accustomed with the micro 4/3 but it was worth it.

Pros: Optical quality is constructive, tropicalized, compact.

Cons: nothing

Opinion: I have always been restìo to use the multipliers as little satisfied previously with the 2x on the white 70-200 Canon. But reading on the net positive opinions I decided to buy it to use it with the 40-150 f2.8 Pro. Well, I am very satisfied. The image quality is still high and the autofocus loses a little speed but nothing striking. I would definitely say better than the two Tamron 150-600 (the G1 and the G2) I've had previously on the D7200 and the 90D. And this is no small thing with half the weight and easily usable freehand. Crazy to get to 600 equivalents at just over a kg. Price in line with the quality it offers. Ps. You have to update the firmware on the 40-150 f2.8 Pro (1.3) otherwise it does not go. This is done from Olympus Workspace and takes a few minutes.

Pros: Build quality, top image quality also at TA, tropicalization

Cons: the same as every 2x, trivially you lose 2 stops

Opinion: Simply fantastic MC20 multiplier. As always, Zuiko multipliers already make the most of TA, since the optics are also designed to work at their best at TA. As a result you can double the 300/4 and use it as a 600/8 without necessarily having to close it. The same with the 40-150 2.8 which becomes an 80-300 5.6. NOTE: I happened to have a specimen of the mc14 a little soft, as soon as the mc20 arrived I noticed that the latter is a blade. Comparing them properly I realized that the screws of the mc14 had loosened over time, compromising the correct slow alignment of the machine body. It was enough to tighten them with a screwdriver to make the MC14 a blade like the mc20.
