MK-N-AF1-A

There was a bit of a learning curve since I'm never attempted macro photography, but after getting used to these tubes, they're perfect. This is a set of 3, by mixing them, you'll find you have different focal lengths. FYI, they are tubes...no glass, I knew this going in, but if you're not familiar with them it may be a surprise to you. If you are new to macro, as I am, start out with the thinnest one to get used to how they work, I kept all of them together and thought something was wrong. This set has the contacts to use the auto-focus on your camera...they worked perfect on my D-7500 and D-7200 and the pictures I had taken...after learning...were perfect. I was a bit concerned, the mount on the camera body was tight but they did work out nicely...good picture quality and they feel as if they'll hold up quite nice. I'm thinking about getting another set to change up the focal lengths.

MEIKE MK-N-AF1-A Macro Auto Focus Extension Tubes In short, these three tubes worked absolutely fine, with no problems in every combination I tried them with three Nikon bodies and two Nikon and one Tamron lens. They each fit one another, and the three cameras and three lenses I tried with them snugly, but not the crazy-tight connection some have reported with extension tubes. Attachments are smooth, firm, and lock with a satisfying click. The set I received looks great, had good quality control, and work in all ways tested for me with several cameras and lenses. My set is just what I hoped for. I sincerely hope other buyers have the good luck I had with my set of Meike Nikon AF macro extension tubes. I ordered from this particular Amazon page because it lists the extension tubes part number as MK-N-AF1-A. This set, the ones shown here and that I received, have chromed metal surfaces where each tube attaches to the camera body, or one another, and also the chromed metal surfaces on the lens attaching ends of ALL three tubes in this set. The bodies of these extension tubes are all plastic. The good quality, high-impact plastic that is sturdy and strong, but still plastic and NOT metal. Only the six tube ends are chromed metal where attachments are made. As best I can tell, Meike makes as set of extension tubes much like this where the end that attaches to a camera mount or other tube is plastic, with no chromed metal surface, while the lens ends of those tubes are metal. I specifically wanted the Meike extension tube set for nikon with metal surfaces on both ends of all tubes, and the electrical contacts and screw drive autofocus mechanisms. I have a Nikon D750 and access to my daughters' Nikon D3200 and D90 cameras. This set of tubes worked, one at a time, with my D750 and the Nikon 50mm f/1.8G lens. Autofocus and aperture changes worked fine with each extension tube up to and including all three of them stacked. This set of tubes worked, one at a time, with my D750 and a Tamron SP Di AF 90mm f/2.8 screw mount lens. Autofocus and aperture changes worked fine with each extension tube up to and including all three of them stacked. I was really impressed that the AF worked with all the tubes stacked though I use manual focus with macro pretty much exclusively. Having the tubes working as advertised, even with an older, third party screw drive AF lens was a good test of these tubes workmanship and alighnment. I used the tubes with one daughters Nikon D90, the same Tamron 90mm Macro screw drive AF lens as described above and a Nikon 18-55mm kit lens. All combinations worked, even the Tamron, since the D90 has screw drive AF capability. Controlling the apertures and the focus on the kit zoom and the Tamron Macro worked without problems for me. I used the tubes with my other daughter's Nikon D3200, a Nikon 18-55mm kit lens and the Nikon 50mm f/1.8G lens. All combinations worked, with the D3200, the various Meike tubes, the kit 18-55mm zome, and the 50mm f/1.8G, in controlling the apertures and the focus. I would absolutely love for Nikon to make a fully metal set of AF extension tubes, but then they'd probably charge $150US for each, and $400US for all three as a set. Since I won't be using these daily, these $50 Meike extension tubes have alread exceeded my expectations, and I've already been having fun trying to determine some fun, neat, repeatable setups for some in home macro work. Health problems keeps me inside more than I'd like, and these tubes add more macro options to my kit than just my Tamron 90mm Macro. With all three of these tubes stacked, and using my Tamron 90mm 1:1 macro on my D750, I get a magnification of 1.64, well over half again the subject's original size. Sweet.

First set was defective. Replacement set was replaced fast and working well. Thanks

Theses work perfectly; autofocus works on all my lenses from old 'D' type (mechanical screw drive), AF-S (ultrasonic) and the latest AF-P (stepper motor). They are well baffled for stray light inside, and have solid bayonet mounts. The body is light plastic, but seems sturdy enough for moderate use, but do lack weather sealing. So, obviously not pro gear, but great for the price. I already have a good 1:1 macro lens (micro nikkor 105/2.8), but wanted the tubes for traveling light to leave the macro at home, and also to use with super telephoto lenses to reduce minimum focus distance for small skittish subjects, like hummingbirds. The few bad reviews seem to be due to people not understanding how macro and AF works. When you push the lens away from the sensor to focus closer, the working f# increases over the lens native f# (bellows effect). Entry level cameras only autofocus uo to f/5.6. if you're using a kit lens at f/5.6 with an extention tube, you will predictably have problems. Higher end cameras will autofocus up to f/8, and lower f# lenses, like a f1.8 prime, will keep the working f# reasonable.

One of the adapters won't disengage without sliding a screw driver into the mechanism. The other two work fine but am a little skeptical for how long. They are fairly inexpensive which is nice and are working fine other than the release button on one of them.

I have had a few of these extension tubes, some good, some not so good. Mostly constructed of metal or an alloy of some sort. However these are injected of a high quality plastic, but please do not let that that deter you. This product has been the best set that I have come across yet. They work with auto focus so that is a plus over many extension tubes in this price range. Some tubes will have a connectivity issue now and then, but I've never had an issue with these. And the support is second to none if your were to have a question or have any unforseen issue, so this is an excellent company to purchase from. A product you cannot go wrong with for close up photography without the cost of an expensive prime lens.

Let me first start off by saying these are great. I just recently got into macro photography, I'm not working with anything special just a 40mm Nikkor DX lens, so I need all the help I can get to get closer to my subjects (on a budget). I find with the two smallest tubes, 12mm and the 20mm separately, I can get up to two times closer and snag some more detail which is great. The 36mm doesn't gel with my rig as there is no more room to move in after 32mm (the 12 and 20 combined). I was worried the auto focus wouldn't work (I'm using a D7500) however it worked flawlessly (plug and play). I really apperciate the build quality of these, you can tell when you try to separate these tubes from a lens or each other they're built tough, you can trust these not to fumble your gear, especially with the metal connectors.

Works, and has given me good pictures While obviously we want lenses and adaptors fit snug without play ... and these do that, and I am not complaining about the bayonet mounting tighness per say, the latch release can be a bit stubborn . Otherwise, it's hard to fail on a lense free ring, except auto-focus which does work, though it is advised you follow their 'sequence' and make absolutely sure the ring is fully, fully set .
