A filter-selection guide for the Sony FE 24–105mm F4 G OSS, model SEL24105G. This is not a comparative filter test or a claim that every accessory below is in the author’s kit. A filter that screws onto the lens can still be the wrong purchase. An ND filter controls how much light enters, a polarizer changes selected reflections, and a clear protector serves a different purpose again. Start with the problem in the picture, not a bundle containing every type of glass. Quick answer: Sony specifies a 77mm filter diameter for the SEL24105G. Choose ND for exposure control, CPL for reflection control, and variable ND when adjustable density is useful and its compromises are acceptable. Check the exact lens model and front-thread size before ordering. Sony 24–105mm lens photograph by Holy-DYVR / Wikimedia Commons, CC BY-SA 4.0. Uncropped; displayed at reduced size.
