I use this (Tiffen 67mm Circular Polarizer) with my Tamron 17-50 mm lens(with hood) and I am much happy about it. Its costly (amateur photography) but well worth the price and it gets the job done (protection and polarizing). Smooth movement and all and not a bit loose.Though I should mention that the outer rim cuts seem to get dented by slight nail pressure, but doesn't affect the polarizer or the lens.

There’s not much you can say about the adapter. I mean it works so what else would you expect? Well, it is well constructed and makes a nice click when installing your lens. I read some of the reviews on the cheaper alternatives and saw reviews mentioning the product feels cheap and how the lens are not firmly and securely attached. I rather not risk it but others have without issues. If you’re on a budget, do look at the cheaper alternative. If you can afford it then this is the one you want.

The adapter is good, delivery was also very fast, i got it just in 1 day.. But if you really wanna use EF or EF-S lens in mirrorless cameras, you have to keep in mind that the sharpness will decrease by a little amount and you you have to focus the subject very correctly, otherwise the picture will become blurry(specially for the prime lens)..

I had previously purchased this item in 67mm for my zoom lens so had no hesitation in ordered one in 43mm for my 50mm lens, these are very good quality items, would recommend.

I have enjoyed using the 67mm filter. It does what it's supposed to.

I am using this lens for Canon M50 Camera. You will need EOS adapter. I have attached 3 photos taken with this lens.

One of my all time favorite filters will always be the polarizer! I bought this one for my new 67mm lens and it works like ones I had for my 58mm kit lens. Another good purchase!

The thing I like the most about this kit is the ability to use on different lens size. Comes with 8 adapter rings (including 49mm, 52mm, 58mm, 62mm, 67mm, 72mm, 77mm, and 82mm adapter rings) so you can use the ND filter with different camera lens sizes. I have used on my Canon EOS R10 49mm and my Nikon D90 67mm. I am new to using filters, but this is a great starter kit.
