I am about to buy a Sony A7RIII + 16-35mm F2.8 GM + 70-200mm F2.8 GM and want to use the same X4 CPL filter. I plan on buying the 82mm X4 CPL (which will fit the 16-35mm) and using a stepup to allow me to use on the 70-200mm. My only question is: will this fit on the 70-200mm with the stock lens hood?


No. It will not. Once you use a step-up ring, the hood cannot mount.

A CPL filter is not very useful on a wide-angle lens, you will get too much brightness differences in the sky. Better to buy your CPL for the tele-zoom lens only.

  • Great tip, thanks! – Madarch Jun 27 '20 at 15:10
