JJC Auto Focus Macro Extension Tube Set for Nikon F Mount D850 D780 D750 D3500 D3400 D5600 D7500 D7200 D7100 D7000 D5600 D5500 D5300 D5000 D3300 D800 D810 D700 D600 D500 DSLR Cameras

Extension tubes are a good option for taking occasional close-ups of subjects. Initially when I fitted both tubes to my camera the autofocus did not work, but after swapping the combination around, and refitting the lens the autofocus worked well, it may have been a sticky contact. The extension tubes fit snugly onto mu Fuji X-T20, and I've tested these with the Fuji 18-55mm kit lenses, the 16-80mm f/4, and the 35mm f/2 lens. I obtained the best results with the 35mm prime lens, and you can see from these un-cropped images the close focusing of the bear, first with just the 35mm lens, then with both extension tubes fitted you can get very close to your subject. For best results use manual focus, I would have liked to have a sample of a focus stacked image, but my X-T3 is away for repair. The extension tubes are well-made, sturdy, and come in a little storage pouch, I'm very pleased

I've liked JJC's innovative and clever products ever since buying their automatically opening lens cap for my Ricoh GX200 camera, many years ago.This set of two macro extension tubes are a real steal for the price in my view. Because there's no additional lens involved, the camera sensor sees a completely undistorted image. The correct electrical contacts are built in to both tubes, so that all the camera's automatic lens functions work as normal. The tubes fit between lens and camera body. They connect in the normal way with a standard M4/3 bayonet fitting.The smaller tube adds 10mm to the length, the larger one 16mm. I can add both together on my Panasonic camera body but it asks me to set it to "shoot w/o lens" if I do. The lens still works though.I know that extension tubes can introduce distortion, especially at the edges, and they cut down the light reaching the sensor. But by leaving the camera on its automatic or Programme mode it will compensate for this if enough light is available.This set is a great way for converting a lens for macro shots cheaply. For some the results won't be good enough for exhibition shots, but for me it's an economical way to see whether an investment in an expensive macro-dedicated lens is worthwhile. I attach a couple of shots of household objects as examples (these have been taken using my camera's automated focus stacking for extra clarity - but that's not necessary to get results).The quality of manufacture is very good, with the tubes mating with lens and camera with no play in the fitting observed. A lens cap and a body cap are included, plus a soft pouch to store the tubes in (with drawstring closure and a sturdy attachment clip).For the price, compared to much more expensive camera accessories, the value is excellent. The tubes work as described and involve no lengthy setup. Recommended with enthusiasm. I tested the Micro 4/3 version.

Fit very well with G9 & Olympus 60 macro.

Didn't work well with zoom lens. Motor really rattled. Bad connection or something loose.

Quite hard brittle plastic but once you play around with them they do work

Used with Olympus M1 ii and various lenses. Can't fault image quality, but aperture data is way off. Not a deal breaker for me, but a bit frustrating

bought for the son in law as it is 'macro season'. he has already used the items and submitted them to various websitesin the hope they will sell

All working as it should great for the price
