For a novice photography, is DxO pureraw necessary if I only use lightroom? The 16mm RF lens that I bought for my new canon r8 (I mainly do landscape, city, street, convention, gunpla photography) has really bad lens distortion and vignetting, and I heard the lens corrections from DxO Pureraw are superior to lightroom. Is this true? How does it compare to lightroom and does it make any difference for a novice photography in the end?
