Lens Extender Auto Focus Close up Macro Extension Tube for Canon EOS Cameras Rebel t6, t6i, 80d, t7i, 5d Mark iv,6d Mark ii

For the price, these are okay. I used them on a Canon 70D with a 50mm f/1.8 STM, 100mm f/2.8L Macro, and 18-135mm f/3.5-5.6. They are very fun to take macro shots with (when they work). If youi want to get good macro at around 1:1 on a budget, these paired with the Canon 50mm f/1.8 STM is excellent. Image quality isn't much worse than the 100mm f/2/8L.Pros:- They feel sturdy enough. I'm not worried about using all 3 tubes with my 100mm f/2.8L lens falling off.- Work as any extension tubes would.- Cheap compared to other extension tubes with electronic connections.Cons:- There is a bit of play when connected together. If you twist the tubes, the lens often loses connection with the camera body and throws errors. This can get really frustrating at times.If you're on a tight budget or don't know if you will use macro tubes enough to justify spending $100+, go ahead and get these. Otherwise I'd highly reccommend spending the extra money to get Kenko or Canon tubes.Images taken with all 3 tubes on Canon 100mm f/2.8L Macro.

So far, I've used this set only for digitizing film slides with my EOS Rebel T6i. I've used the 13 and 21 mm tubes (separately) with either a Canon EFS 18-55 mm or my old 28mm Pentax Takumar. Works pretty well, and I've had no problem with the EF or stabilizer functions. The connections between tube and body and tube and lens are pretty smooth, although the metal tabs on the tubes are not as easy to use as the big button on the camera body. It's actually the connections between adjacent tubes that are a little stiff. The metal tab on the tube closest to the camera body interferes slightly with the big lens release button on the camera body, but it's only a problem for the 13 mm tube and not a large problem even then.Since I've only used one tube at a time, I can't comment on the electrical integrity of 2 or all 3 stacked. I'll just say you should inspect the contacts closely when you open the package. Mine showed just a few small incursions of plastic over the edges of the gold on the back side of one tube. If your incursions are worse than mine, you could have trouble.They included an extra mating set of front and back covers, in addition to the set that was installed and included on the tube stack. Not expected, but useful, thanks, especially if you want to store the not-in-current-use tubes separately. The microfiber cloth seems nowadays to be a standard "extra" to throw in with any camera accessory purchase, but this one is particularly good, and all are handy. There is also a nice velvet drawstring. bag to keep the whole thing in. All very nice touches.All in all, it's a good set. Why not 5 stars? Because I still haven't tried extreme closeups with the full stack of 3, let alone a ring flash powered through the contacts. Stay tuned.***Update*** This evening I had occasion to use all 3 tubes to magnify a small portion of one of the slides I was digitizing. The connections worked fine to drive the EF function, although I can't say about the stabilization function since my SOP is to immobilize the camera relative to the subject in such cases. Additionally, the stacked unit felt solid and there was no hint that any of the 3 would wiggle loose. BTW the red rings, which comprise the engagement mechanisms and seating surfaces front and back, seem to be made of a good quality aircraft aluminum, definitely not plastic. The black tube material may be plastic, but could be carbon fiber material; I'm not sure.I still think I will withhold the last star until I have a little more experience.

These rock. My former tubes required me to mount the lens and shutter-press to close the aperture to where I wanted it (yup, I'm a Canon shooter), then manually focus once I had remounted the tube and lens combination. This is so nice to be able to do macro work with full control of auto-focus and aperture. While they are a plastic body, these tubes have metal mounts (yea!!) which fit better, have less wiggle, and will last longer. Sizing is correct for length (some cheaper tubes vary significantly from the tube size printed on the tube) which allows me to better predict which tube I will need based on the magnification I want. I would recommend these (and have) to anyone looking to play with macro-photography. I don't do that much and thus really can't justify $150+ for a high-quality set of tubes. These are perfect!

I love these extenders. I have a Canon T6i and this fits without any issues. As per operation, your lens will have a limitation of a total distance you can actually extend it. If the camera cannot focus, there are two things that may happen(which was quite odd) 1. You may receive a false reading that your battery is dead.2. You will get a red error screen. This will let you know you have exceeded the maximum range for your lense. Since this is definitely after market, you have to find what combinations work with each lens, that will allow your camera to function properly.For sub-15 dollars, I cannot complain about build quality. It's steardy, and tight(but not too tight) fitting, and leaves you knowing that your equipment will not detatch.I say it's perfect for what I wanted it for. It hits the spot for quality/price ratio.

I picked this set up for fun basically and as a means to expand my creative toolkit in photography. I popped one on, went outside and with 5 minutes of trial and error started to get some pretty cool shots. I couldn't ask for much more than that.They are well made and have worked perfectly with my Canon 60D camera. I've used them so far with my two Canon EF auto-focus lenses (a 24mm prime and a 50mm prime), but I intend to try out my larger collection of Rokinon primes too when I get the time. Taking these extenders either on or off posed no problem, and all the functionality (other than lens distortion correction) you'd normally get with just the lens was there.All in all, this set seriously seems like a bargain for the price. Though some of the inner components may be plastic, everything on the outside is anodized aluminium and very well constructed.

Compre el producto con una expectativa baja y me sorprendió, mi cámara es una Canon T6 y funciona el autofocus conectando los 3 tubos, con un pequeño falso de repente, conectando dos está de lujo y pues uno lo ideal para las fotos que tomo (dentales). Buena compra y claro que me compraría otro y lo recomendaría, no se que diferencias hay entre los otros, el pro y este, pero este me funciono super bien

Very very angry! The first lens is currently stuck on my 18-55mm lens. It can not be removed while the other two are working well. I will have to go see a specialist to try to recover my lens which will cost me more than this purchase. Who will pay me back?Très très faché! La première lentille est actuellement bloqué sur ma lentille 18-55mm. Impossible de l'enlever alors que les deux autres fonctionnent bien. Je vais devoir aller voir un spécialiste pour tenter de récupérer ma lentille ce qui va me couter plus cher que cet achat. Qui va me rembourser?

Excelente producto, el material es metal y plástico, la rosca queda perfecto en el lente y en la montura de cámara (a diferencia de otros adaptadores y lentes mal echos), sólo he probado el anillo más pequeño y da resultados muy nítidos...Lo probé en Panasonic GH4, GH5 con metabones speedboster y Canon T5i, funciona bien el autofoco y la apertura.Venía con una tapa extra de cámara y lente.

Un extra que ayuda mucho si te inicias en fotografía macro y tienes un presupuesto ajustado, el anillo funciona muy bien hay transferencia de datos del lente a la cámara solo un detalle cuando colocas los tres juntos dado su diseño y material aveces hace falso contacto y reinicia la conexión. funciona en mi cámara eos T5

Cheap materials (20% aluminum, 80% plastic). Hard to clip on, release is difficult to depress and feels flimsy at best. When installing the 13mm extension tube closest to the camera body, the tube release hinders the operation of the body's release button (see picture and video). Coupling doesn't line up properly when combining tubes and when you twist the tubes to the lens or body, you can hear and feel the grinding of the contacts against each other. This might damage the camera or lens contacts with time. Markings for lining up on the tube body are unclear: makes It difficult to line up and couple. The combination of unclear markings and relative play within the screw system can cause It to be misaligned and can get wedged inadvertently together.It does function properly and serves its purpose. Contacts transmit signals properly and camera functions working without a problem as shown in the attached pictures.Build quality is horrendously poor and I do recommend paying a little more to get a better build quality, but as a small budget alternative to a high end extension tube, it serves its purpose.
