This is a new thread split from "Kolari Mod's Improvements: A Summary of Tests".

Recently I found a plano-convex lens placed in front of the WA RF lens improves corner smearing.
In this thread, let's talk about the new "Front-End Filter Solution" to get corner-to-corner sharpness.
Basically I talk about SONY A7 series, but the same solution can be applied to ANY digital bodies including Leica!
