[QUOTE="WayneF, post: 213080, member: 12496"] This FX would be the only concern, if in fact any concern then. The DX field of view (and angle of view) is 2/3 of the FX view (1/1.5 crop). It is a FX lens, and DX sensors crop to only use a smaller central part of the wider FX lens view, so it obviously has lots of width to spare on DX. Here is a picture: [URL="http://www.scantips.com/lights/cropfactor.html"]FX - DX Lens Crop Factor[/URL] Even on FX, a step up should be no view problem, so we're only talking about the thickness of two filter rings. I don't know then, I have not seen it, but two filters seems minor that design ought to include? (50mm is far from any difficult wide angle case). My *guess* is there must that much room to spare. But any issue on DX seems unthinkable. :) [/QUOTE]
