GEAR REVIEW: Fotodiox Pro Vizelex ND Throttle Lens Mount Adapter
The idea of combining a lens mount adapter with a neutral density filter is so brilliantly obvious that it’s a head slapper that no one has tried it before. But given the dismal failure of Fotodiox’s Excell+1 Speed Booster clone, I think even Bohus could forgive me for being a little gun shy regarding their new Vizelex ND Throttle.
The appeal of this gear is twofold:
- Combine two pieces of kit into one
- By placing an ND filter between the sensor and the lens – instead of after the lens – various image artifacts can be avoided.
If the Vizelex could do the above without introducing unwanted color shift or reducing sharpness then it would be a real winner in my book. How did it do? I’ll let you pixel peep to your heart’s content and decide for yourself.
Unfortunately, I didn’t have a simple mechanical adapter handy, so the non-Vizelex shots use the RJ Photo Lens Turbo adapter for comparison. I’ve found that adapter doesn’t introduce any color cast or reduce sharpness, so you should be able to notice if the Vizelex introduces any of it’s own. For grins, I also compared it to my usual variable ND filter choice from Fotga and a “quality” 4×4 glass filter, Tiffen’s Black Pro Mist.
