Second in my comparison series is a comparison between the Heliopan Variable ND and the newly released Genus Eclipse Variable ND.
The heliopan ND was one of my early purchases and it has served me well.
ND’s are a must have item whether you buy a fader type on have one in a matte box. It is also something that you can’t be cheap with, why put a poor piece of glass in front of a good piece of glass? i.e your lens.
I am doing this comparison because I recently bought the Tamron 24-70mm VC which has an 82mm filter thread.
I will be testing for Sharpness & colour shift. For this test I’ll be using the 85mm Samyang T1.5 because the drop in sharpness will be greater at longer focal lengths and it’s the longest lens I own.
I did not do a vignette test because vignetting is apparent at wider focal lengths and the widest lens with a 77mm thread that I own is the Tokina 11-16mm F2.8 which showed the same amount of vignetting on both (pretty heavy) and is not a lens designed for full frame. The next widest is my 35mm Samyang and that showed no vignetting on either.
