STOP! Do not cut the Lens Hood out first. Note, it has a flower petal type hood with the longer petal on the top & bottom.------------------> correct It's these longer ones that causes the vignetting.--------------> not correct shading starts at same moment when zooming out Try twisting it to the LH / RH position from the top. Take shots and see the results.----------------------------> cannot twist If it won't budge (after you have tried both the CCW & CW twist), mark the top & bottom petals to follow the petal shape. Now use the smaller 1/4 inch hack saw blade without the handle. Check the photo. Go on cutting by trial and error. Make sure you don't graze the lens. Stick a 3M Post It on the Lens as protection.-----------------------> good idea Then use emery paper to smoothen the rough cut surface. If the LH / RH vertical petals are the culprit too, mark and cut with the hack saw. Good Luck.-----> thanks! Bipin There is nothing worse than a sharp image of a fuzzy concept - Ansel Adams
