Want to ask is only kenko pro (wide) CPL can use on it, as ShingShing sales said that other CPL will have dark corner, is it?

Any other 67mm CPL can use on it without dark corner? Thanks

you must buy a thin one the cpl thin like a normal uv lens
not the one double size
i also buy kenko before aboue 480hkd

but the dark corner is produce by the lens becasue this is a ef-s lens
so if you are not using cpl lens the corner of the lens is little bit dark
but after using cpl lens it will more dark becasue the cpl lens are -1ev


you better use a ef 17~xx lens or making the acperture smaller
the f number bigger

I have doubt on the statement that CPL could create dark corners on a wide angle lens unless you are using a FF DSLR.

Why not try it? Would the salesman reject your request?
