Sold all my Canon stuff for olympus M5 mark3.Started building another setup. Bought the 2x converter for the 40x150 pro lens. One of the best things I ever bought.B&H has the stuff you need. Shipping fast.Today I ordered a new camera case. It has already shipped. Can't beet that.

This increased the zoom to 300 mm, or 666 mm full frame equivalent. Although there is a slight reduction, I feel, in sharpness, the extra reach allows you to get images that otherwise would be highly cropped from the frame, thus losing even more definition.The photo of a dog being walked was shot at ISO 6400, f/5.6 (2x f/2.8, 1/1600, pretty much the extreme conditions one would one to shoot at.

I got this MC-20 2x Teleconverter with my M.Zuiko 40-150mm f/2.8 PRO Lens. While the 150mm on the lens is good, this teleconverters lets me double the focal length with only a little loss of lens aperture. The optics are clean and precise. The teleconverter attaches easily. As an added bonus, this MC-20 Teleconverter works on the M.Zuiko 90mm f/3.5 Macro Lens as well. Now I can take that lens out to 180mm and also increase magnification to 4x! I'm not sure I'm ready to try that yet, but I know it'll work. For now the TC spends almost all of it's time on the 40-150mm.

I use this with the Olympus 300mm prime lens and - - well, basically, it works. You get 600mm magnification and the images are still clear and beautiful. You lose a F stop so shooting at twilight might be an issue - - haven't specifically tested that.What astonished me is that I still do not need a tripod. Basically point, shoot, and get a super clear image. This is with the Olympus E-PL7 camera, which plays a major role in the image stabilization.Note that your camera may need to have its firmware brought up to date to accommodate the MC-20. It's free and takes 10 minutes, but you have to do it.
Pros: It works and gives a good image when used with the 300mm f4 PRO lens (I don't have the 40-150 f2.8 PRO so haven't tried it with that). The camera notes that the converter is attached in the EXIF data.Cons: Long lens technique becomes very important with the lens attached, so you have to be careful if you want sharp images, even with Sync-IS. My own recommendation is that 1/1000 sec is best for this, but maybe with practice I will get that down. Given that the converter means f8, it is easiest on a bright day, assuming you will want to crop (as is usually the case with small birds). It is not a cheap lens, but is probably what you would expect a teleconverter of this quality to be. It might does reduce the image quality a bit, but I suspect the effects of ...

A teleconverter is always a compromise. It's a way to transform a lens into something more than it was designed to be. This 2x teleconverter transforms an Olympus 40x150mm lens into an 80x300mm lens. It does the same for the Olympus 300mm lens, making it a 600mm lens. Or the 100-400mm lens into a 200-800mm lens! But the compromise occurs because these lenses were not designed for those focal lengths and adding more lens elements to the path of the light while at the same time moving the lens farther away from the image sensor reduces the aperture (which reduces the amount of light entering the camera) and reduces the portion of the original optical image circle that exposes the image sensor (thereby reducing the optical resolution).

I've used some 2x teleconverters (like a Tamron model that came with a 500mm catadioptric lens, converting it into a 1000mm lens) that are horrible. The Tamron teleconverter softens the image so much and flattens the contrast so you're almost better off just using the lens without the teleconverter and enlarging the image digitally in Adobe Photoshop or Topaz Lab's Gigapixel AI. But Olympus stands apart. The quality of its teleconverters (both this 2x MC-20 and their 1.4x MC-14) are top quality and work better than any other teleconverters that I'veever used. So, I'm very happy with the results I get with my Olympus MC-20 teleconverter and I highly recommend it. If you understand the tradeoffs that they impose and those tradeoffs are tolerable in order to increase the reach of your lenses, then they can serve a valuable niche in your arsenal of photographic gear. Just remember: You cannot cheat physics. Because a teleconverter (all teleconverters) reduce the light, enlarge the image circle and introduce more lens elements, you will need your scene to be better lit, your autofocus will be a little slower, the range of your in-camera image stabilization will be reduced a little and your images will be a tiny bit less sharp. But, because Olympus has made its teleconveters (like the MC-20) to its Pro-series standard, they are among the best teleconverters on the market and they are fully weather-sealed.
I rented an E-M1 mkIII and an Olympus 300mm f/4 lens for birding, along with this and the MC-14 1.4x teleconverter to test out for birding.It's very small, engineered well, attaches and detaches from the body and lens fine, and didn't affect the handling of the whole rig.The issue I had is that even though it magnified the image 200%, the loss of light/depth of field and the quality degradation made it more of a liability than anything.In field and studio testing, I found that the image quality with the teleconverter was worse than if I shot without it and cropped in to match the framing. With the E-M1, you can use a digital teleconverter which magnifies your view in the EVF 200% so you can check for focus (it still captures the whole 300mm FoV, not the magnified ...

The Olympus 40-150 PRO lens is my favorite lens I've ever shot with - small and light for the range and aperture, fast-focusing, and sharp throughout the range.I've owned and loved the Olympus 1.4 teleconverter from the beginning, and it certainly helps in adding range to the excellent lens, but it's still a little short for small critters and birds. This new 2x teleconverter addresses that issue with aplomb, and with almost no downside. Yes, focusing might be a little slower depending on light, and there might be a small hit in sharpness, but nothing to really complain about for such a small, handy bit of kit.The MC-20 turns the 40-150 into the most versatile, packable wildlife lens you can find.

It's long enough for reasonable bird photography (more range is always welcome, of course, but you'll pay dearly for it on any system), but also, because of the 40-150's amazing close-focus capability, gives you outstanding .84x magnification for macro photography. Nothing else offers this combination - I spent a couple hours wandering around my back yard after receiving the MC-20, shooting anything that caught my eye - birds, bugs, flowers - and got great results all around.Coupled with the excellent updates in the latest firmware for the E-M1 Mark II, this has helped bring the majority of my personal shooting back to my Olympus gear from my still much-loved Sony RX-10 IV - no small feat!
I wasn't sure if this converter was going to be useful for my photographic needs. I've had a Canon 2X for my 500 f/4 for years and absolutely hate it. It's not sharp enough, it really slowed focusing, etc. The Olympus MC-20 is REALLY good on the 40-150 f/2.8 pro lens. Provides a useful range of focal lengths and focuses very fast (nearly as fast as with the 1.4 or no converter). Image quality is superb. On the 300mm f/4 you'll notice a slow down in AF acquisition. Not surprising since you're now at f/8. Image quality is still very good in good light. In low light the focusing will struggle more and consequently image quality is more hit and miss based on the focus acquisition. Still works far better than my other system. In good light, this is a no brainer. ... MoreI wasn't sure if this converter was going to be useful for my photographic needs. I've had a Canon 2X for my 500 f/4 for years and absolutely hate it.

I am using the mc-20 with the 40-150/2.8 zoom and a Panasonic GX8. Wide open, the combination is soft (and less contrasty) at distance, and my subjective impression is it is softer at the wide end of the zoom range. Stopped down 1 or 2 stops, the performance is very impressive. Beyond that things begin to soften, probably due to diffraction. While the GX8 has in body stabilization, at the long end (600mm equivalent), a tripod is needed under most lighting conditions unless one is willing to use high ISO. Unfortunately, unless one is desperate image quality isn't especially good wide open (even with a solid tripod mount) - unfortunate because that is exactly the primary use case for a long telephoto. But, I am keeping the mc-20 because of the high image quality ... MoreI am using the mc-20 with the 40-150/2.8 zoom and a Panasonic GX8.

I can't speak to performance with the 300. Amazingly, one very good use case for this combination is close up photography.
