Easy to mount, the picture quality is very good w/o any fisheye. I would like to see an option that would go from panoramic to more of a subject orientation.

Not always easy to get the function light to activate. Fisheye lens is much better at a distance of more than 10 feet. Bumper case doesn't allow light to show.

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!

Does all the basic stuff pretty well. Lens is quite cheap I get distortion (fisheye) which is annoying as I'm recording tennis matches and the baseline does a shallow smile. Will go for a better camera with more "true" lens

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.

Easy to use, got two lens for the price of one and the new pics are much sharper and more stuff in the pictures without that fisheye deformation from the standard glamour shot lens Apple supplies. I liked the whole usb card thing with the instruction video. Nice touch.
