Zomei®Upgraded Square Filter Holder and 77mm Ring

[sean-g]

has anyone used a Zomei®Upgraded Square Filter Holder and 77mm Ring i have seen one of these on ebay they look fine but i want to know if it vignettes on a canon 17-40L + canon 6D full frame as my cokin zpro filter holder does on this set up even though i have striped it down to just one filter holder

ok i have this filter holder now and its ok it doesent vignetate on the 6d with the 17-40mm lens but the filters are very hard to slide in but this can be overcome by swapping some of the slots round just unscrew them and turn the spacers around if anyone needs a photo of this i can upload one apart from that its 45 pounds cheaper than lee and does the same job could be better quality but it ok for them on a budget and you can get two slide in filters and have a uv or a polorizer screwed in just ask if you need anymore info
