Best Extension Tubes of 2026

Three tubes rather than two is the first thing that separates the Viltrox kit: 12mm, 20mm and 36mm in a 68mm barrel built for Canon's EF mount. That long tube is the real difference. Where a 10/16mm pair tops out at 26mm of extension, 36mm will push a 100mm lens into genuinely tight close-ups, and the shorter rings give you a graduated set of magnifications to work through instead of one big jump.

The contacts are the second thing. On an EF body they keep autofocus and automatic exposure working, which is more than a passive metal ring can offer and a real convenience when you are chasing a moving subject with one hand.

Our advice is to start with a single ring. Viltrox's own note is the most useful line in the listing: one ring, and autofocus is easy; two or three stacked behind a lens shorter than 70mm, and you are fighting the camera for a lock. That matches how the set behaves — the long tube on a 100mm is a pleasure, the same tube on a 35mm is an exercise in frustration. There is also a jump in price over the manual EF sets, and what you are buying with it is electronics and the 36mm, nothing else.

Where it makes least sense is on a crop body with a slow kit zoom. EF-S lenses mount fine, but an 18-55 has little light to spare once you have added extension, and no tube can put back what the aperture takes away. Pair it with a fast prime or a macro-ish telephoto and it does everything the spec sheet promises.

Buy this one for the mount as much as for the tubes. Canon's RF system is still short of cheap third-party macro hardware, and a 13mm-plus-18mm set that keeps autofocus and exposure talking to an R-series body is the shortest route from the camera you own to a real close-up.

Both tubes are metal at the mount and sit flush against the body, so a single ring reads as a slightly deeper lens rather than a stack of spacers. Used alone or together they give you 13mm, 18mm or 31mm of extension, and the full-frame coverage means an RF 50mm or 85mm behaves the way you expect it to. Macro capability is the point, and it delivers without an adapter in the way.

The lock is the thing to check. On some copies the mount stops short of its locking point, which leaves the lens loose and can cost you digital control and autofocus along with it. Click every ring home with the lens in your hand before you hang the camera off a strap, and give a heavy zoom a hand underneath while you are at it.

Adapted glass is the quiet bonus. EF lenses on an EF-EOS R adapter pass straight through the same contacts, so the tube behaves as if it were behind a native lens — useful if you are mid-migration and half your bag is still EF. RF owners pay a premium here for the mount rather than for the tubes, and that is the cost of being early to a system.

The Fotodiox set is the cheapest way into macro in this group, and for a lot of Canon DSLR shooters it is the first tube they ever mount: plain metal rings, no glass, no electronics, and a price that makes the whole experiment easy to justify.

We treat it as a deliberate manual tool rather than a compromised one. With no contacts, an EF lens cannot be told to stop down, so the diaphragm stays wide open and your depth of field collapses to a sliver. That is the deal you are taking, and for a fraction of the cost of an autofocus set it is a fair one, as long as you know it going in.

The workaround is to shoot on its terms: focus by moving the camera rather than turning the ring, light the subject hard enough to hold a fast shutter, and treat the razor-thin plane of focus as the look rather than the fault. If you need to stop down, you need a lens with an aperture ring on an adapter, because native EF glass gives you no lever to turn.

What it does well is the thing that matters most. With no glass in the path there is nothing to soften the frame but your own focusing, and the detail it pulls out of a still subject holds up. Anything that moves is a different proposition — with a millimetre of focus and no way to close the aperture, a bee is a gamble.

Nikon's lens lineup is where a passive tube really hurts. Most AF-S and G glass has no aperture ring, so a tube without contacts leaves you wide open with no autofocus at all — which is why the Extnp set's electronics are the whole point of buying it rather than a plain metal ring.

Three tubes, 12mm, 20mm and 36mm, in a 69mm barrel, used singly or stacked. The maker is refreshingly blunt about the limits: autofocus needs a narrow band of subject distance to lock, and with all three rings on they suggest switching to manual. That is honest, and it matches the optics — every millimetre of extension makes the lens work harder and the camera's job greyer.

Our read is that this is the Nikon set to start with, because the alternatives either cost more or drop the contacts entirely. The build is the trade: the tubes feel light and plasticky in the hand, and a long lens on the end of a stack deserves support underneath rather than hanging off the mount.

Used at its best, it turns a 50mm prime into a close-up lens for the price of a decent filter — the classic first macro rig, and still a good one. DX or FX, the story is the same: longer lenses gain more, wide lenses gain almost nothing, and a tripod makes all of it easier.

Micro Four Thirds gets the lightest set here: the 10mm tube weighs about 21g and the 16mm about 27g, both barely bigger than a body cap. On a small MFT body that matters more than the numbers suggest — the reason to shoot this system is a kit you will actually carry, and a tube that adds nothing to the bag fits that logic.

Autofocus works through the electronic contacts and it holds up: this is the set in the group we have had the least trouble with on that front. Part of that is the tubes and part is the format — at the same framing the smaller sensor gives you more depth of field, so the camera has a wider sliver of the subject to lock onto.

The crop helps on the other side too. A 2x sensor puts more of the frame on your subject for the same extension, so 10mm behind a 25mm or 45mm prime fills the frame faster than the equivalent tube on full frame. Compatibility is broad: Panasonic's 12-60 and Olympus's 40-150 both take it, and a 12-40 zoom on an OM-D body is a well-worn pairing.

Where it runs out is at the wide end, as all tubes do: screw it onto a wide prime and you will be nearly touching the subject. Otherwise this is the least complicated way for an MFT shooter to find out whether macro is for them, and the small outlay makes that an easy experiment to run.
