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

Used with my macro lens that was only 1.5x. Stacked both together (27mm) and increased maginifcaiton to 1.78x. Decreased the minimum focusing distance from 10.5" to 5.5". Maintained continuous AF. Very happy with the product.

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.

I know. I know. Don't expect auto-focus from a third-party extension tube. Except, this brand claimed it would auto-focus with my Canon brand lens and camera body combination. Didn't happen. I have experience with macro images and extension tubes that date back to my neophyte film photographer days in the early 1970's. I'm seriously considering sending them back to Amazon (for the lack of auto-focus). I can compensate manual focus because, well, you almost always need to manually with extension tubes. They seem to be well made. They came in a nice cushioned pouch. They have metal flanges like a more expensive lens to mate with the camera body. There are brass or gold-plated pins that mate with the camera body (so you'd think auto-focus would work). I did not test the camera's ability to adjust or control lens aperture when the lens and an extension tube are used together. I took a decent handheld picture with the largest extension tube in place with an older kit lens (18-55mm AF but not IS). The image was exactly as I expected in terms of magnification. I will retest with much more direct light on my subject but I'm fairly certain there was sufficient light and contrast that auto-focus should have worked. I have several accessories from JJC that's why I bought their product. I haven't reached out to the Seller's customer support (not JJC it's Top Foto).

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).

These aren't the cheapest, in price, but they sure are in quality.They rotate with a clicking sound, and they also shift side to side with an additional second sound.Two axis motion or slop, between expensive camera and lenses cheapens the entire system.They are of course also electrically conductive, and I wouldnt trust that the contact pins are not going to short across the closely spaced corresponding electrical pads given the impressive amount of mechanical slop.Lest you think that the problem is my lens or camera, they are equally sloppy between each other. I have an R5II and 28to70mm f2Overall, very poor quality, and potentially a concern for camera damage.I'll go with OEM Cannon-- after many thousands for a body and lenses, why go cheap on the accessories that connect the two?

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.

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!
