Well, maybe is not exactly a part II, but is an extension of the previous article I wrote about this ND filter, the Light Craft Workshop Fader ND Mk II, very long name for a not that good filter IMHO.
Anyway, in the previous post I was saying that that filter is a big disappointment if coupled with my old, and now sold, Sigma 10-20mm f/4-5.6 HSM EX DC, while with another zoom lens I tried, a longer Sigma 17-50 I didn't have any big problems.
So today I decided to go out and do some extra tests with my brand new wide angle lens, the Canon 17-40mm f/4 L USM.
Now, bear in mind that all the three wide lenses I tried have the same filter size, 77mm, so we cannot really point at the filter size as one of the possible causes. But how it did perform with the Canon L(uxury) lens? Same as the Sigma 17-50 (which shares a very similar focal range) or like the Sigma 10-20?
