I've found this filter to be excellent when fitted to my Nikon 70-300 ED lens. So if you are looking for a great polariser filter you won't go far wrong with Tiffen

I bought this filter for my Nikon 16-35 mm lens. It went on easy and I am happy with the landscape images I have taken so far.

Fits perfect with my Nikon 70-300mm lens. This is just a clear filter used for protection of the outer element of your lens. There is no effect with this filter that I can perceive. It does not cause any unwanted effects either. Some have reported extra flares or whatever. I try every which way I think of to cause that to happen with and without this filter, and could not duplicate those results. If your camera lens does it, well, that is your camera lens. This filter is not the cause.

I got this lens a while a go...the first copy was defected but the second one was the right one....is very sharp considering that is not L series...but the focusing system is very fast...I can focus almost instantaneously...is fantastic considering the fact that is 4-5.6 lens....for everyday shots is very good...I was debating between the version of 70-300 L and this one and I'm glad that that i choose this one...considering the price.... now compared to the 70-300 Nikon version is faster and sharper without doubts,, i have Nikon and canon full frames and regarding to the 70-300 range...this canon beat the Nikon one....for sure...

Great filter, fit perfectly on my Nikon 70-300 lens. Crystal clear and has perfect picture quality. Highly recommend

Fits perfect with my Nikon 70-300mm lens. The effect created by the filter is exactly what I expected, although I am no expert photographer. I will note that the filter does have tiny imperfections visible by naked eye when held at a certain angle to the light. These imperfections are located in one of the inner layers and cannot be cleaned or whatever. I have not notice this impact any of my shots, and they cannot be seen in photographs. Still, I know they are there and they bother me.

I am using this 77mm filter to protect my wife's Nikon 24-120mm VR lens on her D750. The fit is perfect.The filter appears to be of high quality, and they even supply a cleaning cloth.

I purchased this filter to go on the front of my Canon 24-70 f/2.8L lens. It's OK for general family gatherings and such, but I do remove it when I do wedding or other paid work. I have not been able to prove that the image quality is lowered with the filter in place, but it is not the most expensive UV/protection filter that one can purchase.
