[QUOTE="WayneF, post: 373685, member: 12496"] The step-down approach is of course going the wrong direction, but 2 of the 3 lenses listed actually use 52mm filters anyway. The third, 55-300 mm, likely would not be a problem at the zooms long end (a much more narrow view), and also less if stopped well down. Vignetting is at its worst at the zooms shortest zoom (widest angle of view), and when the aperture is wide open. You could take test pictures of a blank wall (an evenly illuminated wall) to evaluate how much it vignets, and when (zoom and aperture). Test both with and with filters, you probably see some vignetting at wide angle and wide apertures anyway. The 50mm uses 52mm filters anyway, but FWIW, it is a FX lens. Use on a DX camera crops off the sides anyway, so a considerable amount of any vignetting would simply already be cropped off. [/QUOTE]
