This allows me to use my older vintage lenses in my canon 200d. Works great and fits the camera body perfectly

Sustainability at its finest. This is how you can make something new out of old. Works perfectly

This adapter works exactly as it should. All old Canon FD lenses work on my 80 D.Bin very happy with it.

Fits. Perfect.

With regard to the adapters from various manufacturers, which were often not exactly positive and the mostly positive voices about this product, I was very curious how the adapter would interact with my old lenses and the EOS 600 D from Canon.
I tested the adapter with old original Canon lenses:

1. Macro lens 35mm - Various plant motifs were photographed and the result was impressive. The objects to be photographed were also displayed on the camera's fold-out screen. In some cases, however, I had the impression that the light sensitivity setting was not reproduced faithfully on the screen. But after I experimented a bit with it, it worked satisfactorily.
2. Zoom lens 70 - 210 mm - The zoom lens can be focused without any problems even with the largest zoom factor (which has been criticized with many other adapters. The images in the viewfinder are displayed correctly on the camera screen. And the resulting images are flawless.

The The adapter itself can be easily attached to the camera and does not come loose when changing the lens. The two lenses used could also be attached to the adapter without any problems and are firmly in place.

Overall I am totally satisfied with the adapter. I do not know if a professional would do the same would see, but for me the resulting images are really good, especially when you consider how much money you save by using the old lenses.

It's great that I can use older lenses on my EOS with the adapter.
We recommend

I've read through many product reviews here, where it said you should keep your hands off it, rather grab a more expensive product (> 50 €). That's why I didn't have such high expectations of the adapter, if necessary I would have returned it.

But here one must say unequivocally that the product has far exceeded my expectations. I don't have expensive FD lenses myself. The most expensive one I own is the 50mm 1.8. I get very good pictures with all FD lenses. Of course, the best way to focus manually is to use a tripod or photograph fixed objects. With playing children or animals it is of course more difficult.

I am completely enthusiastic about this and can only recommend this adapter. Compared to "normal" Canon lenses like the 55-250 IS, a 200mm FD lens with an adapter and manual focusing can really keep up in terms of image quality. For proof I've attached pictures I took with a 2x teleconverter and a 200 Carenar 3.5 at f/5.6. My camera is a 1200D.

This is the second time I have ordered from K&F Concept and for the second time I am extremely satisfied. The quality is worth the price. I have the adapter for my new (actually old) 28mm Canon FD optics. The attachment of the adapter is easy, the construction is stable and the quality of the images is impeccable. Thanks!

The adapter works. I purchased for my Canon EOS 80d, to try using 2 of my father’s old FD lenses, a 35mm lens and a telephoto. The adapter does its job fine. There is a flare/glare as others have noted but im a novice and that doesnt bother me. I just adjust my angle slightly away from the flare but i can see how professionals wouldnt like it. Also, you will lose several f-stops and will have to compensate with your cameras settings otherwise your photos get overexposed. I had to adjust my shutter speed so slow just to compensate to the point where i couldnt see the photo on the LCD screen, I had to wait for the photo preview to see how the exposure turned out, then readjust until i got what i was happy with.
Turns out my old lenses werent that great and in the end some old lenses may not be worth trying to use. Make sure your old lenses are worth the trouble.
Id say if you have expensive, good quality lenses and you want to try it out, for the $55 CAD i paid, im happy i tried it out.
Otherwise, you may just end up buying new lenses.

I got the old lenses from CANON as a gift for an AE1. Why not use them when there is this helpful adapter. It fits in my new EOS and saves me buying an expensive Canon lens. I use the old ones. Perfect. And for me as an "occasional snapper" a great solution. Recommendation. MK
