FocusFotoPro Automatic Electronic Macro AF Auto Focus Extension Tube DG Set 10mm + 16mm for Olympus Panasonic Micro Four Thirds M4/3 Mount GH3 GH4 GH5 GX85 E-PL8 E-PL7 E-M5 E-M10 Mark II III Cameras

Defective product; Defective design: The connections on the side supposed to be flat are sticking above the surface as a result when attaching to other ring or camera, there is a cogwheel like effect and not smooth as it should be. likely to damage camera connections after a few uses. plus the risk of metal shavings falling into camera chamber can cause damage to the sensor as well as other moving parts. Do not buy. Will discard. Not worth the trouble of returning, paying with time and shipping.

Thank you! the spacers that where sent had issues. Corrected problem. It was awesome how fast i received another set. Awesome product!

These do not work on some Olympus cameras. I tried them on E-M1X, E-M1 mk II, E-M1 mk III, and E-M5 mk III and all I got was a black screen. However, they did work on an Olympus E-PL6 and E-PM2, as well as a Panasonic GH4 and GH5. Yes, I have all of these cameras. And I have Pixco and Kenko tubes that work on all of them.

Panasonic's Micro-4/3 42.5mm f1.7 is egg-sized, famously sharp, weighs only 4.6oz = 115g, and autofocuses to about a foot = 30cm, about 0.4x life-size., which was nice, but for this pussy willow bud, I wanted to get closer, almost life-size. This set's 16mm extension tube between camera and lens quickly did the job. It connects the lens and camera electronics, preserving automated focusing, exposure, and lens & body integration of image stabilization, a major Panasonic advantage. I like tubes better than closeup lenses, which degrade the image optically as well as via added dirt and reflections from two or more additional surfaces and can shatter when dropped.

Man I thought these were tires one night but they are amazing still
