I keep this filter on my main 18-55mm lens on my Sony NEX-5R. I have never had any issues with it. I've taken out in the snow, rain, and dirt/dust. It has never scratched and has been great for protecting my camera and enhancing my photos. I have a pack of these threaded filters and can only stack two before the vignetting gets too severe.This is definitely essential camera gear to have!

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!

Fits perfectly on my Sony full frame 50mm f1.8. So satisfying to replace a missing lens cap!

f1.8という絞りで、ピンポイントでビシッとピントが決まり、前後が綺麗にボケてくれます。ポートレートの表現力を高めてくれました。

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!

Fits nicely into my Sony 55mm lens. Love the variable filter and the photo quality is very good.

you get what you paid for. It's not a product like B&W.Wonderful for sony zeiss 55 1.8. I touched the glassed in the lens and made some scratch and then decide to get this one. This filter can really protect the lens from unintentional touch.

This is a great tool assuming you have the Sony FE 14mm F1.8 GM Lens. If you *do* have this wide angle Sony lens, this will allow you to use both 1.1mm thick and 2mm thick filters in the 100mm Kase system. This is just the filter holder kit for the aforementioned lens--you'll also need a magnetic 90mm CPL filter. Excellent product for the specific lens/use case.
