Review on 📸 Movo Photo AF Macro Extension Tube Set for Micro 4/3 Mount Mirrorless Camera System (Compatible with Olympus Pen, Panasonic Lumix, Blackmagic Cinema Camera) - 10mm, 16mm, and 21mm Tubes by Jessie Burgos

They are excellent. They work with my gh4 and 14-140mm lens and I can get really close. They are also automatic or usually work in manual mode. They allow you to take very close shots. They work with all three of my lenses. Panasonic 14-140mm Olympus 75mm and Panasonic 25mm. I tried them at 25mm first and it was a bit frustrating to find the focus on auto, I switched to 14-140mm and it was like night and day. Just a tip I didn't know if you've never used them before, moving the lens an inch closer or an inch back makes a world of difference :) They get used a lot.
