This thing screwed on perfectly to the Sony 35mm 1.8. No complaints. Also have this on my 50mm 1.8L Canon.

Im using it on my Nikon 28mm f/1.8 and Nikon 85mm f/1.8. Same diameter on both lenses.

Hey, I'm PercyI'm a YouTuber (Gogglez Enraged) that does reviews, tips, recommendations, and top gears to get.Build quality of the 50 f/1.8 is very cheap (as you might expect). This lens feels more like a toy than a piece of optics. It utilizes plastic construction right down to the lens mount (the lenses are glass of course). This light material combined with the small size (2.7" x 1.6"/68.2mm x 41.0mm - WxL) puts this lens in the featherweight class - 4.6 oz (130g). The 50 f/1.8 is currently Canon's lightest. It was also Canon's shortest EOS-mount lens until the Canon EF 40mm f/2.8 STM Lens was introduced. The Canon EF 50mm f/1.8 II Lens delivers very sharp images as inexpensively as Canon lenses get.The 50 f/1./8 bears a plastic lens mount. Considering how light the 50 f/1.8 II lens is, the plastic lens mount seems adequate from a strength perspective. You might get more wear than you wish if you are changing the lens frequently.Autofocus is driven by a micro motor. Focus speed is not stellar, but fine in good light with subjects that are not moving too quickly. The 50 f/1.8 II is one of Canon's louder/buzzier lenses - you know when it is focusing. But this is not a wildlife lens - and the noise probably won't bother most people. I suppose a positive aspect of the sound is that you know when it is working - and when it is finished working - when focus is locked. FTM (Full Time Manual) focusing is not included. The 50 f/1.8 extends up to 5/16" during focusing - the very small 52mm filter does not rotate.All in all, I truly enjoy using this lens for my B-roll for my Youtube channel and the webpage. As well as having those awesome blur shot background. i highly recommend purchase this lens cause its inexpensive and a good lens to have around because of its size and the picture quality.

Inexpensive filter protection for my 85mm lens. Fits perfectly!!!

Amazing colors and smooth picture quality with the Sony a7iii and Sony 85mm f/1.8 lens

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.

update:using the eos m3 i compared the images from this lens to a few i just took with the older canon 85mm 1.8 lens. even though the 85mm cost like nearly 3 times more. the 50mm 1.8 STM in my opinion had both sharper image quality and much better coloring. side by side the 85mm 1.8 seemed washed out, so much that i went back to redo a set a photos i just took with the 50mm 1.8 instead. If you have a newer canon digital camera like the eos m3 , i would highly recommend the 50mm 1.8 , not only will you save money but overall much better image quality and usability as you dont have to step back so far, but still looking very nice![older review:]I was a bit hesitent to buy this lens as i already had the 50mm 1.4 USM which is a great lens but the one i had started having some sluggish autofocusing issues and in some points simply would not autofocus right (more so if the image was fully blurry and you were trying to focus on something sometimes it just would not focus) But i just bought the Canon EOS M3 (on ebay) and decided since it was a nicer faster camera then the M1 maybe it would be worth trying out the 50mm 1.8 STM as i hear it was faster in focusing and lighter weight too and even a bit sharper wide open. After tryng it out i must say it really is very nice VERY fast autofocus compared to the 50mm 1.4 in my opinion. Sharp and produces nice blurry backgrounds. Does not feel cheap. I mean it def doesnt feel "pro like" BUT it doesnt feel like a toy in my opinion just about the "Right" quality for something like this.For non full frame cameras this likely is the BEST Option you can get for starting out with wanting to take more photos of people. as cropped sensors make it more like a 85mm lens so you get a nice flattened image of the person without having to stand too far back (which can be better in many situations).I think after years of trying diffrent things ive found the best solution for photos of people is this lens + the canon eos m3 (with adapter) so that you have a nice compatish camera that is not too heavy or bulky and very fast and sharp!My issue with the 50mm 1.4 was that sometimes inside it didnt "grab" the image good or it took too long or it wasnt quite as sharp or whatever. Much like the EOS-M 22mm 2.0 lens which is a great value for the price, this is as well (if not more so since you really can use this better for pictures of people).If your a bit new to photography and want to take images to stand out vs all these "cell phone selfies" Just get one of these you'll be amazed at the quality and the possibilities it opens up for a great build and price! I liked it so much i put the box for the 50mm 1.4 in my drawer and proudly put the box for the 50mm 1.8 STM on my dresser because i think for now ive found it is the BEST Lens canon has for the price and what it can do to make great photos of people. Cant wait to use it even more!
