Take a look at the NiSi range of products. I use several of their ND filters down to 17mm with no vignetting but do need to remove my uv filter first. Not cheap but excellent quality and great colour accuracy

Thanks Marcus, I actually have the lens on my 5D MkII and have been really happy with it, I just wondered if there were any specific issues related to it's use on the 6D MkII which I plan to purchase very soon Cheers

I'm considering buying a 6D MkII and have the 24-105 F4L MkI lens. I wondered if anybody is using this combination and if so what you're impressions are? My main interest is landscape stills rather than video. Thanks
