JJC EF & EF-S Mount Auto Focus Extension Tube Set for Canon EOS 90D 80D 70D 60D 77D Rebel T6 T7 T5 T8i T7i T6i T6s T5i T4i SL3 SL2 EOS 6D Mark II 7D Mark II 5D Mark IV III 5Ds R 1Dx Mark II and More

This product is great and is extremely affordable! The only thing that is a bit of a negative with the product is that it takes a bit of force to mount it to the lens, a little more that I’m super comfortable with, but it fits snug and I haven’t feared I’m going to hurt my camera or anything. The photo shows some 1:12 scale (6”) figure photography I took with the 20mm extension and a 18-55 mm kit lens.

- Full autofocus, electronic manual focus, exposure, and aperture control.- Easy to install; mounts to body just like any other lens, and lenses can be mounted as if it were a body. To remove lenses, just need to pull back tab in the adapters. The adapters connect to each other just like lens and body.- Feels sturdy, both adapters appear to be strong plastic with metal face- Uploaded examples using 25mm lens with the 10mm adapter, and then using both 10+16mm adapters

Works great on my OM-1.Couldn't find out a lot about these so I just picked them up on a whim. My 12-40 f/2.8 lens is practically useless with both tubes attached as it places the focus plane practically inside the front element of the lens.Conversely, my 40-150 f/2.8 works fantastic. Around 70mm I can place the front of the lens a good six inches away from the subject. Basically, the zoom works as the rough focus, and the focus works for very fine focus.Definitely cheaper than a 90mm macro lens, but the usability is nowhere near a dedicated macro lens. Worth the $40, easily, especially if you aren't doing serious macro work and just wanna mess around.Attached is a roughly 40% crop of a photo taken around 70mm @ f/2.8 of the mesh on top of my microphone, SOOC large jpeg set to fine+neutral.

Initially, I ordered another brand from a reputable (?) photo source and it was described as an extension ring with metal mount. To my greatest surprise, it was actually a nicely painted cheesy plastic mount. I returned it. I abondoned the photographic source and I stared searching Amazon. What a great source to find things that you need! The JJC extention rings for Nikon Z mount lenses were exactly the opposite of what the other ones were not! Both sides of the extension ring mounts (camera and lens) were made of metal (aluminium and brass, respectively), nicely machined and great copper contacts. It worked well and precisely. When you mount both rings there is a sligth play between the two rings what for me is expected. You can't completely eliminated the play less you play the game that the ring can get stuck on the camera or lens. Also, it comes with a really nice bag where you can store it safely and cleanly. Thanks Amazon for the variety of products you offer and JJC!

Autofocus does not work with them at all on either Nikon D3500 or D7500, tried all three individually, and all combinations. Cheaply made and feels like they could break easily just by mounting them to the body of the camera or mounting a lens on them. While one feels loose, one feels too tight mounting, and one seemed ok. Returning asap.

These feel extremely cheap when installing, but the work perfectly fine. I probably wouldn’t buy them again, but I’ll use them until they break ✌️

Work on Nikon camera

Ok

Bought these extension tubes to try out macro with my R50. They've been holding up well after a month of daily use and swaps. There's some play between the tubes, but it's nowhere near enough to lose connection to the lens. Overall, they're a great option for anyone looking to try macro on RF mount without diving into buying a full macro lens.

Because there is no glass and because this is basically a spacer between the lens and camera body, I could not justify spending 4x more for the Fuji brand. All three work smoothly without issue so far. I only need them occasionally so I’ll have to see how long they last. So far so good.

De extras: bolsa protectora acojinada, con clip para colgar de la bolsa de la cámara, y tapas delantera y trasera.Como dice el título: muy buen maquinado y perfecta transmisión de la conexión entre el lente y la cámara, ambos anillos o los dos en conjunto. Ambos apilados permiten acercar un tele corto a solo milímetros del sujeto. De 35mm hacia atrás solo se puede usar uno de los dos anillos o casi se hará contacto con el frente del lente.La sujeción (montaje) es firme pero fácil de accionar y de liberar.El uso de anillos de extensión logran una calidad de imagen casi como de un verdadero macro y desde luego muy superior a un lente de aumento de +1 o +2 dioptrías, ni decir más.Siempre he quedado muy satisfecho con los artículos de la marca JJC, son, por lo general innovadores o copias perfectas del original y de muy buena calidad sin pagar precios de marca.En este caso, los recomiendo, de nuevo, ampliamente y sin reservas.

Funciona muy bien y la cámara canon con las que la use la función de auto enfoque y apertura del diafragma funciono correctamente y sin problemas, use un lente RF estabilizado con enfoque electrónico y todo funciono muy bien, es una de las pocas piezas que funciona con montura RF. La calidad de materiales se siente muy bien. totalmente satisfecho con la compra (Canon EOS RP). Incluso use un lente montura EF con el adaptador a RF original de Canon y estos extensiones macro y enfoque automatico funciono bien al igual que el diafragma y la cámara reconoció todo. Me importaba mucho el auto enfoque para poder hacer con la camara el focusstaking que tiene la camara. recomendado

I already have glass at various focal lengths and never could justify the hundreds of dollars to get a dedicated macro lens. These extension tubes are the perfect solution and I can enjoy the same optical quality I expect from my existing glass.Autofocus works great and it literally transformed my existing lenses into macro ones. Super compact too, a great accessory to keep in the bag
