Step-down ring for 75 mm holder
The Benro Master DR6746 is a step-down adapter that lets a 67 mm filter mount onto a lens with a 46 mm thread. It is designed for photographers who use the Benro 75 mm Professional Filter Holder system and need to fit smaller-diameter lenses into that workflow.
Thread-mismatch limitation
A step-down ring reduces the front diameter, so the filter glass becomes larger than the lens opening. This can introduce vignetting on wide-angle lenses because the filter rim encroaches on the image circle. The adapter adds 0.5 cm of thickness to the optical path, which may affect focus stacking or close-up work where every millimetre counts.
Check lens thread and filter size
Verify that your lens has a 46 mm front thread before ordering; other thread pitches will not engage. Confirm that the filter you intend to use is a 67 mm circular type, as square or rectangular filters require a different holder. The ring weighs 9.07 g and measures 7.9 cm across, so ensure your lens barrel can support the extra diameter without fouling a hood or cap.

Questions about this item
Should I choose the 67-46mm ring or a different step-down size for my 75mm filter holder?
The DR6746 is the specific 67mm-to-46mm adapter for the 75mm Professional Filter Holder; select it only if your lens has a 46mm thread and you need to mount a 67mm filter.
What does the 67-46mm designation mean when I attach it to my lens?
It lets you screw a 67mm filter onto a lens with a 46mm front thread, adding roughly 0.5 cm thickness and 9.07 g weight.
How does the 75mm Professional Filter Holder interface limit what I can mount?
The ring locks into the 75mm holder system, so it only accepts filters that fit the 67mm front thread of this adapter.
