Has anyone used this adaptor from Hitech? http://www.bhphotovideo.com …mm_Wide_Angle_2_Slot.html![]()
It's like the Lee 150mm system for the Nikon 14-24, but has adapter rings available for many more lenses, including TS-E 17L, 14L II, Samyang 14mm, Sigma 8-16 and many other lenses with bulbous front elements.
Any idea what filter thicknesses it can take? Hitech filters are 1.5mm thick, but many others are 2mm thick - any idea of it can take these other filters?
