JJC Micro 4/3 Auto Focus Macro Extension Tube Set for Olympus OM-3 OM-1II OM-5 OM-D E-M1 III E-M5 E-M10 III E-M1X Pen E-PL10, Panasonic Lumix G9 II G7 G85 G95 GX85 GX9 GX8 GH7 GH6 GH5 GH5S GH4 & More

This set of macro extenders is constructed well. The extenders have metal connectors. They are easy to install and disconnect. The images I am getting with them are excellent. I am attaching some of the images I got with these extenders.

Initially, I ordered another brand from a reputable (?) photo source and it was described as an extension ring with metal mount. To my greatest surprise, it was actually a nicely painted cheesy plastic mount. I returned it. I abondoned the photographic source and I stared searching Amazon. What a great source to find things that you need! The JJC extention rings for Nikon Z mount lenses were exactly the opposite of what the other ones were not! Both sides of the extension ring mounts (camera and lens) were made of metal (aluminium and brass, respectively), nicely machined and great copper contacts. It worked well and precisely. When you mount both rings there is a sligth play between the two rings what for me is expected. You can't completely eliminated the play less you play the game that the ring can get stuck on the camera or lens. Also, it comes with a really nice bag where you can store it safely and cleanly. Thanks Amazon for the variety of products you offer and JJC!

Pretty good over all, but it's slightly loose. Using with A9iii and GMaster lens, it's not quite up to Sony's quality, although it is usable.

I just received my extension tube set. The mount coupling is a little sloppy, but the contacts do whatever they need to do. I tested it out on my Canon R5 Mark II with both the Canon RF 24-105mm f/4 IS USM and my Canon RF 70-200 f/2.8 IS USM lenses. If you're planning to shoot nature stuff but don't want to put out the $$$ it's well worth the price. The extension tubes hooked up perfectly to my lenses and the auto focus worked well. Of course, moving the camera back and forth to get a rough idea of your (very narrow) focusing range is a learning experience.I've enclosed some quick shots taken to check the sharpness. Note I'm primarily using this for nature stuff, so my main concern is sharpness at the focal point. These shots were taken at maximum aperture and extreme ASA/ISOs (10000-128000) except the Canon Len Hood ("only" 6400).

Had a difficult time auto focusing and even when I went manual focus, the results were less than spectacular. Shot with Canon 5D Mark II 50mm 1.4 lens at f 4.0. Tried both auto focus and manual focus. First pic with the extender, second pic without. Glad these were inexpensive. The quality of the product also felt cheap. Not the sturdy stuff I'm used to. If I decide I really need an extender, I'm sticking with Canon product.

Did not fit for my camera. Seems nice though

The media could not be loaded. Works perfectly and it also came with a nice bag. The bag was too nice for the extension tube so I use the bag with my nifty 50. Great product and I would buy again.

Set of two (10mm and 16mm) JJC extension rings arrived yesterday. Metal construction; solid lockup, no wiggle. No problem with focus and aperture etc. signals between camera and lens. Bought them to play on my Pana GX85 with the kit lenses; first camera with interchangeable lenses.Looked at several sets on Amazon, picked this JJC set as having decent reviews and being a bit above average in price range. (Yes, you can pay too much and get trash, but rarely get satisfactory quality without paying for it.)The 16mm is too much extension for the 12-32mm lens. The 10 and 16mm rings, singly or in tandem, work well on the 45-150mm lens. Have done some macro pics with single lens cameras, but camera is so close and blocks even lighting. Extension ring on the long lens gives a very tight angle of view from several feet back. No camera shadow.
