Canon Ef 50Mm 1 1.8

[Bayonet] I bought this for my Canon EF 50mm f/1.8 STM and it fits firmly. Feels well built and the release button works well too.

[Metal] I use this to attach a Canon EF 70-200mm f/2.8 L II and a Canon EF 50mm f/1.8 STM to a Canon M6 Mark ii, and so far the results have been outstanding. Also it's a much more economic alternative to the much more expensive Canon adapter.

[Aluminum] I lost the lens cap to my Canon EF 50mm f/1.8 STM Lens and needed a new one so purchased this replacement cap. It fits perfectly!

[4 x 4 x 3.25"] Fits the Canon EF 50mm f/1.8 STM Lens perfect! (great lens, by the way)

[Close-Up] I bought this to use with a Canon EF 50mm 1.8 lens and it works wonderfully for macro photography. Image quality does not change with adding this lens and maintains its sharp details. Works best with manual focus and tripod but that's true with any macro lens

[0.475 lb] I’m using this adapter to adapt my Canon EF 50mm 1.8 and more specifically my Helios 44-2. Both work great on this adapter and especially on the Helios. It lets me see the full image projection which allows for the special “swirly bokeh” the Helios is known for. It’s a pretty basic adapter but it’s exactly what I needed and quite a bit cheaper than the alternatives. It’s manual focus of course but with all the focus assist tools on the X-T5 I have had zero issues getting focus. I would recommend!

[3.6 x 3 x 1.4"] Great addition to the Canon 50mm EF little lens.

[0.01 lb] I use it on my nifty fifty and my ef-s 24mm. I put a 67mm ND fader on it. You can really touch the quality. It's not a cheap metal ring. It has texture. So, it is easier to put screw in and out. Note that the smallish focus ring of the 50mm 1.8 II is hard to handle with the ring on. Autofocus will be your only solution for certain situations. That problem will not occur for other lenses (or the newest 50mm 1.8) where the focus ring is not on the very end of the lens.

[Bayonet] I bought for my Canon EF 85 mm f/1.8. I wish Canon could sell the lens with the hood.

[0.3 lb] Just the tweak I needed with my Canon 1.8 50mm lens. Great price too!
