Mcoplus EXT-M3/4-M 10mm 16mm Automatic Extension Tube For Olympus Panasonic Micro 4/3 system Camera

Great bit of kit,I can now take close-ups with auto focus working. Understand that the auto focus will only work if you are close to the subject. The picture was taken at Aperture priority set at F22. Duration was auto at 1/30 sec, ISO 200 with the lens set at 134mm and flash GN10. Distance to target approx 12 inch. Picture quality will depend on the lens and camera sensor as opposed to only adding magnifying 'filters' to the front of the lens.

Two tube rings which can be stacked offering 10mm, 16mm or 26mm of offset between lens and camera body. They work well for reducing the lens minimum focus point and allowing macrophotography. If you have choices of lens as well as these tubes it takes some experimentation to know how to position for a given subject and works best with a very stable camera set up. As claimed they pass data between camera body and your lens so that autofocus and exposure still work but only once you have subject and camera within the new working distance range.They fit well with my MFT body and lenses. So far they seem to be a good quality product and hence good value compared to some of the other much more expensive equivalents.

Good value for money, seems well made and robust. My camera (Olympus omd eM1 ii) which has class leading auto focus, struggles to focus with any of the tubes on. This is probably to be expected as I’m using the tubes with a 60mm macro lens so the focus distance is small and dept of field is paper thin at this magnification. I find the best method is to use manual focus, and move the camera back and forth.

A good addition to the kit for a low price. Does very good job and very easy to use. Most versatile extension lengths provided.ProsLightweightNice fit in camera and for lensCheap addition to get decent close up shotsConsWorst packaging when shippedHunts a bit even in good lightThe lens release clip are tight and looks flimsy

It fit my olympus OM-D M5 Mkiii without any problems at all. Autofocus and appature fuctions worked fine with these fitted. Useful for macro shots . good vlue when compated with other items.

For the price these are a really fun addition. Be aware that as they are simply extenders you will find image quality suffers. chromatic abberation and vignetting will increase regardless of the quality of your lens as it isn't designed to have this massive gap. The fit is OK but has a slight wobble, which may be disconcerting with any heavy lenses. I compared using these with a rather large telephoto zoom lens to my 60mm macro lens, and whilst the image quality simply couldn't match, for the price you can't really go try. A good way to explore macrophotography without spending a load.

I wasn't expecting much from these tubes as they were cheap, however I thought it was a good starting point for my journey into the world of macro photography.How I was wrong!These tubes are fantastic, I use them with a 45mm 1.8 to gain close up images of bugs, the detail, the colour, the AF is spot on! They are a little tricky to use with such narrow DOF but they are perfect.Would totally recommend them.

works with my Zuiko 75-150 zoom and OM-D-e-M10. ; experimenting with closeups
