This is my 2nd product I've purchased from Viltrox. The first one was for their EF to EF-M speedbooster. This one was for my EFS to EFM use. Way cheaper than the Canon version, and works great. No problems at all with mounting and AF.

I bought this for my Canon EFS 17-55 mm f/2.8 IS USM. I am still using it on the same lens and is doing a very good job without distorting or altering the images. Great stuff

This fit my 18-55mm EFS Canon lens just fine. Seems to do what its supposed to. Good price, fit, and quality.

Used this adapter with several different lenses of mine and a friends and it works perfectly with all of them. This adapter allows you to use EF or EFS lenses easily on the Canon RP.

Works great when using EF lenses for my Canon M50.

Works as advertised. The elastic strap for the lens body tube fits both of my Canon Lenses, EFS 55-250mm and EFS 18-135mm. The adhering pad for the lens cap works best on the smooth surface edge where there is no logo underneath.

Works perfectly on my Canon T5i with the base EFS 18-55mm lens. Worked so well that I ordered another for the EFS 55-250mm lens I also have. No problems whatsoever with either lens.

Received my Canon EOS Rebel T3 about two weeks ago. I bought the kit with the EFS 18-55 lens & the EFS 55-250 zoom lens. Great camera, simple & fun to use especially for a novice. This camera is light weight but still feels solid even with the 55-250 lens attached.Wow is the T3 easy to just pick up & start shooting pictures. Excellence entry level DSLR camera for an amateur/novice photographer, good balance of ease of use, quality & price. Great purchase!This camera was rejuvenated my old photography hobby. Thanks Canon.
