Hi mate, I hope you are keeping well,
Great review as always,
Take care of yourself,

[alunlambert]

Great Vlog, very informative, you talked about the stepping rings, are they just the normal set you can get from them, then the filter is the magnetic bit.

[marcustan]

Just got all the information I needed from this video here. Great work!

Is there any difference in image quality to use the largest size filter with step up rings comparing to using each individual filter size for each lenses? Leaving the costs aside.

Very nice review. Would 35mm lens FF have this vignetting issue or it is not too wide for this?

[reflux]

Do you know if this would fit on a canon sx50 bridge camera? All i know so far is that i need a "filter adapter FA-DC67A", but im not sure if this adapter already has the filter adapter that would fit. Im not sure what to buy.

There are 3 types of k&f uv filters which one would you recommend, thanks alot

[zjadaczkitu]

Nice review! Do they offer nd64 magnetic on their own?

[cristibaluta]

How is the cpl filter turning, is it sliding on the magnetic ring or it's exactly like a normal cpl filter?

[alexmdelfont]

Thanks for this, would they vignette using tamron 17-28mm on full frame?

[profenx]

From 49mm filter size to 77mm will knockout the vniting from laowa 9mmnf2.8 ?

[BrianHallmond]

I wonder how these compare to the Neweer ones?

I also bought this product. One thing I like it BUT on their website it is said even with all 3 filters no Vignetting with 16 mm wide lenses. That is not true at all with 16mm and ND + CPL Filter I get really bad Vignetting in all corners. I am suing a 67 mm lens. Would it make any differences getting the 82mm kit and use a step up ring?
