I thought, "Hey it's just a simple extension tube with a Nikon mount. No moving parts. And it's cheap! Why spend more?"I should've spent more and so should you! DO NOT BUY THIS! YOU WILL REGRET IT!It connected to the camera just fine. The connection was difficult at the lens. After some fiddling, it seemed OK, but after I moved the focus ring and took a couple more shots, the lens fell off the extension tube. I removed the extension tube and reconnected the lens direct to the camera to assess the damage. It will not autofocus anymore and the aperture is forever at f/32.This cheap piece of junk extension tube turned my favorite macro lens to a piece of junk. Hundreds to repair it or more hundreds to replace it.Let my experience save you! DO NOT BUY THIS!

Conforme à mes attentes photos nikel tout manuel Resultat probant

works as expected!

Nice quality, fits the camera and lens properly, threads between sections well machined and clean.Exactly what I was looking for to photograph printed circuit boards.

Sem queixas.

at the beganing i didn't understand how to use it after that i found how to use it it realy macro perfect product put need light to be close of the item

The macro extension tubes gives anyone a good level of freedom to shoot very close to the subject and thus fill in the entire frame. For any non-macro lens we all know that the higher the focal length, longer the subject distance (in other words 'minimum focus distance') has to be else the pictures will be all blurry. This is due to the basic principles of the optics which we cannot beat in order to take macro shots. However by increasing the distance of the lens with the camera sensor, we can decrease the minimum focus length. So in short any lens can be become a 'macro lens' if you can mount it a few millimeters away from the camera sensor. We should note that higher the distance of the lens from the sensor, higher will be the magnification ratio. To achieve this there are several products in the market such as bellows tube and extension rings. Again there are two kinds of extension rings, one which can let you autofocus on the subject and second which cannot autofocus.This product we are talking about basically is a set of rings of varying sizes and will not autofocus on any lens or body. The zoom, the focus all has to be manually set. If you are pretty comfortable with manual lens and has lots of patience to shoot macro, you may want to try with this cheap alternative before you buy an expensive set. Trust me, this is well worth the cost and a good product to start with. Since, it is manual we cannot change the aperture on certain lens such as Nikon G lens. With Nikon D or lower lenses, it will work great as you can now change the aperture manually if in case required. Note that, with G lenses the aperture will be wide opened as soon as you mount it on the tube as they got a small latch to do that.I tried it with all the ring for the largest magnification with a 50mm prime lens and discovered that the distance to the subject has to be very small, around a few inches and manual focus is a big pain. You will have to play a lot in order to get the perfect shot, however the magnification was seriously high. Then I tried with Nikon 10-140mm G lens. As soon as I mount the lens, I could see the aperture wide opened giving me the maximum amount of light. With the extension tubes on, now the minimum focus distance decreased to a few inches with the ability to zoom in or out. Put the lens in manual focus and now you can adjust the focus with both zoom as well as focus ring. The depth of field was just perfect like a dedicated macro lens. The magnification was too much with all the rings, set; so I tried removing the longest one. You may have to try different combinations of rings to get the magnification you are looking for. The only drawback I could see is, as you stack the rings, there will be a decrease in the light by around 2 stops. Therefore you definitely want a Speedlight flash or just shoot outdoor with plenty of light. The lens can be demount easily by pulling the metal screw back and unscrewing the lens in an usual way.I took several pictures with this zoom lens and have posted the pictures at the link: I would definitely welcome any kind of comment or suggestion.[...]Note: not all of the pictures are taken with the extension rings.The shipment arrived on time and was well packed. Now I have given up the idea of buying a dedicated macro lens since they cost a lot, instead I have ordered the Autofocus extension rings. I hope this review have been informative to you, if it was please if this review was useful on the amazon link. Thanks for reading and happy shooting.

I bought this item after reading all the reviews. I don't ordinarily submit reviews, but so many of the reviews I read for this product struck me as bogus that I felt compelled to write a review in this case.First of all: if you're looking to puchase extension tubes as an inexpensive way to take closeup (or even macro) photos - please, do all of us a favor and read up on them first. Think about what sort of lens you're going to use them with.If you're seeking to couple extension tubes with a Nikkor G-type lens (look at the lens: does it have a "G" at the end of its designation?), and you really want to retain the ability to autofocus, these are NOT the extension tubes for you. (But ask yourself why you think you need to retain the ability to autofocus? It's virtually useless with macro or closeup photography). Not only will you be unable to autofocus (because these extension tubes don't enable communication between the lens and the camera - what do you expect for $8???), BUT as others have noted, you will find the scene very dark (as the aperture will be stopped down). If you insist on using extension tubes with a Nikkor G-type lens, please get a set of extension tubes that allows communication between the lens and the body. And be prepared to pay a lot more money.If you're trying to couple it to a relatively short lens, be prepared to need to get within an inch or two of the subject before you can focus on it.Be advised with all extension tubes that you may lose the ability to focus on infinity. Also recognize that extension tubes will rob you of some light. This is true of all extension tubes. You just can't break the laws of physics.If, on the other hand, you have an old manual focus lens, or even an autofocus lens with an aperture ring (you know, the thing that allows you to set the aperture manually?), then this is a handy addition to your kit for very little money. To be sure, the threads are thin, and the set is lightweight, so I'd think twice before coupling this to a heavy lens. (All of my heavy lenses are G-type lenses, so I won't even try mounting this set to them). Still: you gain a lot of versatility for very little cash outlay if your lenses are relatively light in weight.I bought this to go with some old manual focus lenses I've recently purchased (a Russian Helios 58mm f/2 lens and an East German Meyer-Optik Gorlitz Trioplan 100mm f/2.8 - check out the latter group on Flickr). I didn't have any trouble attaching or detaching the extension tubes to the lenses; having read the reviews on Amazon, I knew not to bother trying to turn the knurled knob on the ring that connects to the lens, but simply to pull it back toward the camera body to release the lens. Piece of cake.I played with the extension tubes with the Trioplan lens last night. I'd discovered that the minimum focusing distance on this lens without any extension tubes was about 40 inches. A bit of a bummer as I'd bought it because of its wonderful bokeh, and I was hoping to use it for closeup shots of flowers (among other things). But by adding just the 7 mm extension tube, I could get the minimum focusing distance down to 18 inches - enough to allow me to fill the frame this morning with a Lenten rose, with wonderful background bokeh. (And next time I'll use the tripod that hadn't yet arrived in the mail).Why pay more? Sure, it's lightweight, but photography is an expensive hobby, and I don't mind saving on things like this where the build quality has absolutely no impact on the image quality. It'll allow me to buy that next lens (or monopod head, or neutral density filter) all the sooner.
