Mcoplus Extnp Auto Focus Macro Extension Tube Set (12mm 20mm 36mm) for Nikon AF AF-S DX FX SLR Cameras

UPDATE:I am changing my rating to 5. The picture of the grasshopper was taken in the wild with all three tubes on a Nikon D810 with a Nikon 80-400mm lens on manual focus. These tunes are sturdy and supports my heavy lens just fine.For the price they are great. They work. However you need to learn how to use them if you have not used extension tubes before.The BAD:- The 12mm tube is broken. Amazon promptly replaced the set. Now everything works.***AMAZON REPLACED THEM WITH NO QUESTIONS ASKED. THE NEW TUBES WORKS FINE.- When I use more than one tube the autofocus does not work. It searches and on rare occasions will lock on but the shutter will not release.*** DON'T USE AUTOFOCUS. IN TIME IT WILL ANNOY YOU SO BAD. MANUALL FOCUS IS MORE RELIABLE EVEN ON A MACRO LENS THAT HAS AUTOFOCUS.The build quality:They do not feel cheap to me. But they are plastic with metal bits that connect them together. I have one pretty heavy lens and I support the camera by the lens just to be safe. Dropping a $100.00 lens is not funny and I am not going to take that chance. However these extension tubes do feel pretty solid.THEY EASILY SUPPORTS A 3+ POUND LENS. I HAVE BEEN USING IT ALL TAY AND I HAD NO ISSUES.The good:- That price. Yep that price and that they work really well except the do not autofocus w\as promised.- Image quality. Judge for yourself. This is what I got. Your experience may differ depending on a lot of factors.- Build quality. For plastic they are solid and holds even my heavy 80-400mm lens. However I do support the camera by the lens because the lens is heavy.Final thoughts: You really don't want to use autofocus when doing macro photography. So manual focus is better. therefore I really cannot find any real fault with these extension tubes.

Excelente extensión macro!

Over a period of time, I have found these rings to be very serviceable. After initial stiffness got worked through, they have been easy to mount and dismount from the camera. I am able to make closeups of areas about the size of a fingernail, and of course larger.The directions were not very useful, being a mix of very general warnings and highly technical notes. Fortunately, the situation is simple enough that trial and error was a good approach.I didn't try the automatic focus. I expect that most people who are getting this technical with their photography would prefer manual focus anyway.

12mm and 20mm tubes worked great, autofocus worked on my nikon d90 and lens release/lockup was fine. The 36mm tube evidently got the least amount of work. I couldn't get my lens unstuck until I searched through these reviews and read a note directed to another unfortunate buyer from the seller to "use a screwdriver". I did the same thing and realized the release tab doesn't depress the lens latches enough. Additionally, any AF lens couldn't connect to the 36mm completely and would instead spin the motor endlessly and "click" like it was stuck. AF lenses would not even shutter when set to manual. I strongly recommend a different set of tubes. They will all work the exact same, hopefully a different seller has better quality control.

Good product. Great intro to macro photography. Feels a little cheap but have had no issues with attachment. I swap them out a lot when trying for different magnification levels and they seem like they will hold up. I have not tried other brands but at this price point I assume they are all about the same. They work fine with AF/metering on my D7000 even when using all 3 and I have not had any weird behavior so far. Definitely get a set like this one that has the AF/metering connections. With this set and a standard 50mm prime lens you can get some very close shots. You can also use these with a dedicated macro lens to get even more magnification.A couple tips for this setup: You will move the camera instead of the focus ring in order to change focus so manual focus mode is recommended. Depth of field is extremely shallow - a tripod is very helpful unless you have very stable hands. For static subjects it helps to have a focusing rail, otherwise you can just move the camera slightly and take a bunch of shots. "Live View" mode is very helpful in focusing since you can set the aperture high and still see your DoF/focus on the screen. If you are going for a "budget macro" photo setup, I'd recommend you also pick up a reversing ring and aperture control set for another 30 bucks or so. For extreme close-ups you may need to use "focus stacking" software like Zerene Stacker to produce the images you want. This is a solid alternative to an expensive dedicated macro lens and I am very happy with it.

I've been experimenting with these extension tubes for a couple of weeks now, and in my experience, they work as expected when used individually. However, once you start stacking them, there is a pronounced "hot spot" in the center of the resulting images. Some creative side lighting can help mitigate this, but there is clearly some internal reflection at work here. It's quite disappointing actually...to the point that I would like to return them.
