Perfect fit for my Nikon AF Nikkor 50mm lens. Looked high and low to find this. It is a nice snug fit and will not come off if jostled or stuffed into it's case.

Nice set of filters for protecting my expensive 50mm F/1.4 lens. Easy to put on, can be added on top of each other to create nice effects if desired

Great lens, mine just came today and I didn't have any shoots planned so I tested it on my son. I shot on Nikon for about 3yrs and recently purchased a Canon 70d with the 50mm being my first lens (other than the kit lens 18-55mm). I'm use to shooting with a Nikon 50mm and so far the Canon looks up to par. Great build quality and bokeh, and good depth of field. Probably get the 24mm next. I'm still new to the 70d and so I still have a few settings to learn but I'll update once I use it for an actual photo shoot.

For my Nikon 50mm. this is best polarized filter i got

Got this for my Canon 5D IV and Canon 50mm 1.4 lens combo, and it does not impede any image quality. Pretty happy with the results, and glad that I can keep dust and fingerprints away from the actual lens.

I use a Nikon D3100, I bought a Nikon 50mm f/1.8D AF Nikkor Lens. That lens has 58mm threads. I bought the 58mm Tiffen Circular Polarizer filter to use on that lens. At the time of my order it was sold and fulfilled by Amazon. I paid for shipping and received the filter in less than four days. The filter came in a hard plastic box that I use for storing the filter. It looked new and works fine. No filter problems and I give it 5 stars. The only issue is screwing it onto the lens is a bit tricky because you only have half the width to work with but I blame that on my fingers and lack of any real nails. I have noticed that if the filter doesn't go on straight it may make a glare effect but when I see that, I rescrew it on and that takes care of the issue.

I've had the Canon 50mm 1.4, and now this lens. and I can honestly say this one is better. This one focuses fast, it's small, looks great, is bitingly sharp, even wide open. and can easily be used professionally. I bought this just to have a lens, any lens on the front of my Canon 6D, but it's amazing. I'll be keeping this one. My 50mm 1.4 USM lens had major, major backfocusing problems, which I've read is not uncommon for that lens. I ended up selling it, even though it was a sharp lens. The focusing was terrible. This one is dead on, sharp, and contrasty. It's also probably the cheapest lens you can buy. If shot wide open, it's VERY sharp in the center, and there is definitely some slight vignetting (although it looks good in portraits, which is presumably what you'd be shooting wide open), and a "swirly" quality to the bokeh. I was taken aback by it, but it's cool. Almost Lensbaby-ish. Definitely get this lens!!!

Probably one of the best lenses to have in your kit. It's small and light weight and pretty inexpensive, especially for the quality it gives. It's perfect for nearly every situation.I had one for my husbands camera, which is a Nikon, before getting a Canon and buying this 50mm Lens and I must say, I like this one much better. The fact that you can use auto focus with this lens, whereas the Nikon 50mm for a manual focus only, make this lens leaps and bounds better.
