Interceptor121 843 Posted May 1 The 28-60 has distortion correction set to on and can't be switched off in camera However you can turn that off in lightroom and the lens shows vignette afterwards This is hood vignette When I use the WACP-C at distance closer than the recommended extension i get vignette on the rear lens not the hood I believe the flat port 45 is 3mm too long and as result you have this problem Share this post Link to post Share on other sites
Interceptor121 843 Posted May 2 Looking to the amount of distortion the lens has by itself I think the lens field of view uncorrected is in effect wider than what a 28mm lens would have the reason why I disable lens correction for distortion is because it improves the edge performance when used on a curved adapter. As the image is not straight anyway it makes sense to do so Obviously a small lens like this has many compromises baked in distortion and vignetting are very strong so it is assumed you use the lens correction but I only really use chromatic aberration correction that can't be switched off Share this post Link to post Share on other sites
