ProMaster Step-Up Ring 67mm – 72mm

Machined perfectly smooth threads on this ring, so screwing it onto my lens was buttery and didn't cross-thread even once. It's thin enough that it doesn't add noticeable bulk between the lens and filter.

Finally, a step-up ring that doesn't cross-thread or wobble—this one's machined smoothly and fits perfectly between my lens and filter. It's thin enough that I didn't notice any vignetting on my wide-angle shots, which was my biggest worry.

Threads the gap between my 67mm lens and a 72mm filter perfectly, and it spins on smooth without any wobble. I've used it on a few shoots now and the fit is snug enough that I don't worry about it loosening mid-frame.
