Commlite CM-EF-EOS R lens mount adapter

I bought this adapter simply because the original Canon adapter is out of stock from all the places (no idea why is that, I searched over 2 months for the original Canon adapter without success). The adapter works great, the quality feels good and I have no complains at all.

Initially I wanted the official canon adapter, however these were out of stock with no date for restocking so I bought this instead. Although I can’t compare this generic item to the branded Canon adapter, I have to say that so far I have been really impressed with what it does. All my EF lenses (Canon 100-400l mk2, Canon 100 macro, Sigma 150-600, Sigma 150 macro) work perfectly with all functions operating as I would expect. At at least half the price of the Canon adapter, I have no hesitation in recommending this item.

Bought this during lockdown to use my Canon EF lenses with an R series camera. Canon UK and every camera shop in UK were out of stock. Even now 10/2 they are predicting a mid march date for the Canon equivalent. So took a gamble and bought this. It is well made, was sell packaged and, so far has worked well. If you have a new Canon R seies camera and want to use your EF lenses, give it a go. So far so good!

Used to put old Nikon digital wide angle zoom lens without aperture ring onto Sony A7 R2 and works very well even at full uncropped sensor size. Used manual focus and exposure. I can select aperture via the f stop ring on adapter, very useful adapter. The focus ring on lens is corrected so infinity setting is maintained. Supplied in a very useful strong plastic box, has a good strong connection of lens and camera body and fitted tripod mount foot.

On receipt I attached my lens and found the autofocus didn't work.

High quality, feels solid, works perfectly with my auto focus lenses.

I bought this with the aim of having a cheap adapter option to put as permanent appendage to a couple of my cheaper lenses. Similar size to the official Canon control ring adapter. The Tripod adapter comes off easily but when fitted is not square with the body, it's about 5-10 degrees off kilter. It fits all my lenses but does not work with all of them.: Canon 100-400mm F4.5-5.6 EF L (mk 1) - AF working OK but it's giving a strange humming sound, as if it is hammering the IS... Canon 50mm F1.8 - Working without issue. Sigma 150mm APO Macro DG HSM - Working without issue Sigma 18-300 F3.5-6.3 DC - AF hunting and never locks, Heavy fringing at 18mm , small fringing at 300mm. So the more expensive the lens the more likely it is to work, which is counter productive for me for not spending the extra 40 quid for the official adapter.... So I will keep it and leave on my Macro lens, but I will have to use an official Canon one to leave on my 18-300 lens or the 100-400.

I bought this due to non availability of the canon adapter. It was OoK to start with although occasional glitches in connection. Connection problem got progressively worse when using it with the 100-400 mk ii. The connection plates came loose and despite screwing them in, connection was unreliable. I think it is just not up to the job when used with heavier lenses. Have since found a source for the canon adapter. I advise caution using this adapter with heavy lenses.

正直純正品ではないので、本当に大丈夫かと半信半疑で購入してみましたが、全く問題ありません。ガタとか接触不良なども今のところ皆無で満足してます。

値段が安いからあまり期待しなかったが、いい意味で裏切られました。工作精度は非常によくてレンズ側とボディ側ともにバックラッシュや不快な遊びもなくしっかり装着できます。きつくもなくゆるくもない。唯一の欠点は少し重いことですが、しっかりした素材が使われていると思えばいいです。

Acheté pour mon Canon R5 pour monter mon parc objectif EF-S. Fait très bien le travail. Satisfait.

Wer sich eine Sony Kamera kauft (und von Nikon kommt) kennt das Problem: es gibt entweder nur sauteure oder sehr unzufriedenstellende Linsen. Mit diesem Adapter steht aber die gesamte Welt der Nikon Objektiven offen. Ich hab die Bilder oben mit einem Nikon 35mm f 1.8 geschossen. Man sieht dabei, dass es gestochen scharfe Bilder sind - der Adapter funktioniert also bestens. Objektiv und Kamera sitzen bombenfest, nix wackelt. Eine kleine Herausforderung ist die Blendenverstellung. Hier gibts einen Ring, der mit Blendennummern nummeriert ist (das war für mich ein Hauptkaufgrund). Andere Adapter haben zwar auch einen manuellen Blendenring, aber ohne Nummerierung. Wie geht man also vor? Man stellt am Ring eine Blende ein und tastet sich heran. Das hat man ziemlich schnell im Gefühl - die Nummerierung am Ring hilft bei der Orientierung. Falls sich Qualitätsmässig noch etwas ändern sollte im Laufe der Verwendung, werde ich die Review anpassen. Kann ich mir aber derzeit nicht vorstellen, weil der Adapter gut verarbeitet ist (metall) und ja keine optischen oder elektronischen Teile vorhanden sind.

Correcte à l'usage. Il faut bien savoir que l'ouverture ne s'affiche pas. Il y a forcément une déperdition, même si les photos restent convenables. Sur les a7, vous pouvez vous aider du “focus peaking“ du boitier pour la mise au point. Bref il n'y a pas de miracle, mais concernant ce produit, son prix, il n'y a pas à être déçu. J'utilise un voitlander Ultron 40mm 2 et un 28mm 2,8 (monture AIs). C'était évidemment mieux sur mon boitier Nikon. Aucun reproche à faire à ce produit.
