Förvånad över hur bra dom fungerar. Billigt och bra i kombination med mitt Sigma 105mm....och mitt tålamod.

Ces bagues s'adaptent parfaitement à mon CANON EOS 250D / Objectif EF-S.La mise au point automatique est fonctionnelle, mais nécessite une tenue stable de l'appareil. Comme attendue, la profondeur de champ est limitée.La construction est robuste, l'assemblage sur l'appareil ne présente pas de jeu.En conclusion, c'est un bon achat pour un prix acceptable compte tenu de la qualité du produit.

I am very pleased with these extension tubes for my Canon 90D. They are built solid, feel like great quality, and do an amazing job!

An extension tube set can be a very useful accessory for going beyond mere close-ups and entering the domain of macro photography for a DSLR owner. Kenko’s manufacturing quality and pricing levels provide a useful alternative to similar products from camera OEMs. This product has performed wonderfully and for many can bridge the gap between a standard or standard-zoom lens and a macro lens. The Canon EF mount of the Kenko set serves EF-S and EF mount Canon cameras and lenses equally well.

These have a nice heft to them. They are just empty tubes, so there is no effect on image quality, but understand that these are for macro photography and you will lose the ability to focus at infinity. The most important thing with this type of extension tube is having the electronics from your lenses working through them without problems. I tried the 3 tubes in different combinations and had no issues whatsoever. They mount to the camera with a solid feel and have no play. They are substantial enough in construction that I have no fears of a heavy lens breaking them. You get a set of 3 tubes for what you would pay for 1 Canon tube.

I tubi sono solidi e non restituiscono quella sensazione plasticosa che si può provare con altri prodotti più economici. Ciò che importa per un prodotto del genere di fatto è che sostengano l'ottica evitando che cada a terra e finisca in mille pezzi, e con questi tubi direi di stare tranquillo.Sono presenti i contatti, quindi mantengono gli automatismi per autofocus e diaframma, e consentono un buon aumento dell'ingrandimento.Unico neo secondo me è il prezzo, poiché parliamo di un prodotto al cui interno non c'è assolutamente nulla (nessun elemento ottico) e potrebbe costare qualcosina di meno, però credo che per chi cerca questo tipo di accessorio questa sia una delle scelte migliori in assoluto.

I wasn't real sure how these were going to work out....Gotta say that I'm well pleased with this set.I don't shoot a lot of macro...certainly not enough to justify a dedicated macro lens.But I figured adding some extension tubes to my bag might give me a couple more options when needed...Just before I almost purchased the OEM tubes...I figured, "What the heck...these are cheap & seem to be well regarded...worst case; they dont work and I'll send 'em back."Well I'm happy to say that they work GREAT.I can maitain AF for the most part and exposure is a no-brainer.They attach nicely and generally feel solid. Not up to Canon feel & weight (or build)...but certainly acceptable for my use.The electronics work just fine.The caps are fairly cheap so I replaced those with Canon caps because they're a bit more robust. Though the ones provided are probably more than adequate. That's just me.Like I said, I don't shoot a lot of macro stuff...but just the other day needed to shoot a couple of watches...These worked a treat and the watches are gone (sold)...so the set is more or less paid for. Score.And it was only after I started looking that I discovered that Kenko has been around since like 1957. O_oI guess I never caught on that Kenko is Kenko Tokina...and they own several other companies like Slik & Tasco...such it the way of things when one is focused on only a few brands. Now I know.Regardless, these are well worth considering.

These feel sturdy and release/engage well. I agree with some of the other reviewers, not sure i'll ever use the largest tube. On an 80d it completely messes with the auto focus and live preview, but despite that the shots come out well. For studio photography these plus a 50mm lens work good for photographing jewelry. In the real world where speed was an issue, I suspect a dedicated macro would be needed.

I don't write reviews, this will be my first. But this is one product I feel deserves one. In short, just buy it. You won't regret it for one second, and it's worth every penny to me.Build quality of the Kenko is excellent, feels very solid. The hinges of each tube engage very well, feels secure, and releases cleanly every time. The electrical contacts work exactly like they should, and in all combinations, unlike some others that have contact issues with one, two or all three tubes used together.I've used this on my EFS 60mm F2.8 Macro and my EF 50mm F1.4, and both feel secure and work perfectly with this. I even tried it on my EF 70-200 F4L and it works perfectly fine. The autofocus hunts if you don't have adequate light, as the falloff is about two stops with all 3 tubes together. But since I use it with my Macro lenses, I rarely use autofocus.Reading some of the reviews, I went into this purchase expecting this extension tube set to be perfect. I got perfection. And don't worry about it being compatible with only EF or EFS. The tube ordered from this page is compatible with both.

I am sure that once you decide to journey into the world of professional macro photography you will probably want to go ahead and invest in something a little more permanent than these Kenko extension tubes, however for the amateur like myself these Kenko extension tubes are a great starting point.When you pop these out of the box, your first thought may be "Why the heck do they cost over a hundred bucks?" and honestly I think it'd be a fair question. Other than the fact that it seems like all items having to do with photography come with huge price tags, I'm not really sure. The body of the extension tubes are mostly plastic with metal rings and screws at the end caps - that's really about it. I will say that the machining of each piece is very precise, I had no flash or bits of plastic left over on the edges anywhere and the contacts for the auto-focus connections were flawless and worked perfectly. But when it's all over and done with, these are pretty much just plastic tubes with circuit contacts.But are they worth it?Well, when the other option is to go out and buy hundreds (thousands) of dollars worth of macro-specific lenses in order to dabble in macro photography, then yes. And if the only other option is to buy a single "name brand" extension tube which costs as much as this set of three, then yes. There is nothing wrong with these Kenko extension tubes and I will admit to having a lot of fun when using them and they work great, but there are a couple of things to keep in mind...1 - Do you really need the auto focus to work while working with macro photography?I sort of regret paying for the extra autofocus feature on these tubes because honestly, you're probably doing most of your focusing manually. "Fast" and "handheld" usually does not go together in the same sentence as "macro photography". Now having said that, two of my customer example photos were taken by hand - but they were also taken in burst mode and I had at least ten to fifteen rejected shots before I found a nice sharply focused shot that I liked.2 - Are you going to get serious about photography? (Or are you in a class?)These extension tubes will literally "extend" the usefulness of your basic lens set, but they are not a replacement for a good macro-capable lens. If you're thinking that you're going to do a lot of macro photography or that you'll upgrade to a full macro lens in the future, you may want to skip the tubes altogether and save up for the glass instead.Now, if you're an amateur like me who likes to dabble in photography and likes to play with toys, then absolutely - get these extension tubes. They're a heck of a lot of fun and allow you to take those really awesome close up shots without having to spend hundreds of dollars buying macro-specific glass. If you want to save even more money I think the non-autofocus enabled versions are worth a serious consideration.
