p.2 #8 · p.2 #8 · New FUSION ND Throttle Auto Adapter with aperture control | |
I have some comparisons now. It's an end of the driveway test on a wooded lot. I tried to catch as much sky as possible to give a clear color cast and dreaded X performance comparison.
It became cloudy quickly during my testing, but there is still enough clear sky for color comparisons.
The brighter top portion of the 145mm ND filters is from the sun coming into play more during testing.
I don't usually do these things, so be easy on any critiques please.
These images were all shot with the Sony A7r1, Tamron 15-30mm EF mount.
As a time saving measure, I used Aperture priority. Some higher ND images had overall exposure increased a little in order to appear uniform.
The left columns are with the MB IV-T, no ND filter.
The next column is with the Fusion ND Throttle. There are not any ND markings, only a min setting, max setting, and tick marks in between. Including the min and max larger tick marks, I counted a total of seven ticks. Tick 1 corresponds to the min setting, tick 7 corresponds to the max setting.
In the second sample there is a third column using the MB IV-T and the Fotodiox 145mm front filters. As a basic comparison, I put the 6ND filter next to the last row and the 10ND filter on the last row. The stops don't exactly add up, but I think worthwhile for a basic performance idea.
Feel free to download them. They are the largest sized jpegs I can upload to my site.

My impression -
No dreaded X
Until near max, the Fusion ND Throttle has a warmish color cast.
At max the color cast is a little cooler with a bit of purple.
The Fotodiox 145mm 6 and 10ND filters have an equal amount of color cast, both being a bit purple. I think in post this could be easily corrected. The passport color checker would make it exact.
It definitely saves space in my bag if I'm not planning on doing landscapes with my Canon body.
I'd still need the 145mm front filter for pure polarizer use.
