Must not be missing in any photo backpack. I am very spoiled by my L lenses, e.g. 100mm 2.8 L IS USM, 70-200mm 2.8 L IS USM II. The 50mm can keep up well from aperture 2.8, it is really depth-of-field from aperture 5.6 to 11. Aperture 1.4 makes no sense at all , the center is not big. Optics 5 stars, AF USM 5 stars, performance 5 stars. You should order the lens hood at the same time, you need it anyway. To avoid damage to the focus, you can simply leave the lens hood on at all times. I also tested the plastic cup 50mm 1.8. I wasn't happy with that (optics 0 stars, AF 0 stars, performance 3 stars). It's better to save money and buy the 1.4 right away, that's a lot more fun.

ABSOLUTE BUY RECOMMENDATION!!!!!

For beginners, the price is unbelievable and you also get a lens hood that costs more from Canon's original than this whole set would take in its place immediately

I'm really happy that this filter can be screwed onto my Nikkor Z 24-70 f/4 S with the lens hood in place. Obviously I need to reach into the lens hood to adjust the filter, but that's ok. No vignetting that I can see.
The filter works great, nice smooth action and a great range of density.

Works very well, I only recommend buying an additional lens hood because if there is backlight in the picture, it looks purple in the picture. Nevertheless, I am very satisfied, it does what it is supposed to do, I can't complain

Best cheap functional lens cap

I use the 67mm version of this filter. Since there are no external threads to mount a hood (I use this with a stepup ring for other lens sizes), I use a 67mm Amazon product ($9.50 for two) "67mm Camera Lens Hood - Rubber - Set of 2 - Collapsible in 3 Steps - Sun Shade/Shield", Mount the rubber hood BEFORE the VND, fold the rubber back over the lens, then mount the VND, set it where I want it, then pull the rubber hood out over the VND adjustment ring. A little awkward, but it works.
