I was unsure if this would fit the Sony FE 50mm F1.8 lens… fits perfectly and appears to be the exact same lens cap model that lens comes with!

Very sturdy even with a DSLR and 18-135mm telephoto lens. Folds nicely to a compact light weight size. Some parts are light weight plastic but as long as you don't overtighten they should be fine. A good compromise between weight and durability. Well worth every penny. A must buy.

Pros:For the price, it's absolutely worth it. I got my 80D with the 18-135mm kit lens. Compared to that this 50mm picture quality is much better (sharper, less grainy, better with low light situations). The bokeh effect and blurred backgrounds are easy to capture. Good introductory prime lens.Cons:Sure the build is mostly plastic, but that doesn't bother me.At f/1.8 it's hard to keep things in focus, as it constantly needs to refocus as you or the subject moves. This may just be an issue with the wider aperture. Shooting at around f/2.8 helps.

I'm a huge fan of prime lens and 50mm is one of those sweet spot focal lengths that should be in every camera bag, if not on the camera itself! Canon produced a massive hit with the affordable f1.8 50mm, dubbed the nifty-fifty. It was succeeded by the II, which sadly saw some corners cut in build quality with the transition to a plastic base. (While I have commented in prior reviews that I challenge the "need" for metal mounts in smaller, lighter lenses, I can't help but admit that I prefer a metal mount.). This latest iteration of the venerable "nifty-fifty" sees the return of the metal mount and upgrades the focus mechanism to the silently speedy STM stepping motor!OpticsWhat's not to love about a f1.8 lens? The optics are excellent as you would expect from the reputation of its prior versions. Talk about a fast lens, you can take some pretty incredible shots in poor light conditions with this. Beautiful bokeh! It provides excellent separation of your subject from the background, as if they jump out of the picture. I was very pleased with my results on a recent flower viewing trip. Terrific color representation, minimal chromatic aberration and distortion. It will not disappoint!Focus mechanismIf you haven't tried STM yet, prepare to be amazed. Fast and quiet! Great for video work too. I'm very happy with the Canon STM lineup.Build QualityAs mentioned previously, the metal mount has returned. (I can hear the cheering!). The barrel feels a little less sturdy than the 24mm and 40mm pancakes, but all in all, it's an improvement over the prior version. Considering its price, it is quite an impressive piece of work.PriceCheap, it would be hard to imagine anyone not happy with the priceMy recommendation is to run outside right now and buy this lens. You won't be disappointed.5 stars. Thank you Canon!

I bought this to go along with my 24mm stm pancake, 18-135mm kit lens and my sigma 18-35mm art lens. For $125 you really can't go wrong. The stm focus is loud especially compared to the kit lens which is basically silent. I paired it up with a JJC LH-68 hood and the whole package is light and small. Not sure if I need the 24mm pancake now.

I have been using my 50mm f1.8 canon lens for about a month now. Love the clear sharp images it gives! So glad I made the decision to purchase it.

The lens fits perfectly on my Canon 50mm f1.8 lens. No complaints here.

It's a lens cap. The correct, OEM lens cap. There's not much more to say about it. I needed one for my 50 f1.8 so I can sell it properly. This is it.
