Review on 77mm to 82mm Step-Up Lens Adapter Ring for Filters by Breakthrough Photography: Premium CNC Machined Brass with Matte Black Electroplated Finish by Kevin Taharka

This boost ring works well. The textured, knurled handle is very helpful when trying to unscrew the filter. Being brass it helps with sticking threads and blackening should help with glare/unwanted reflections for example. It should be noted that unlike my other adapter rings that I have received from another manufacturer, this one does not have a case. The packaging was a plastic zipper, This included a ring and a microfiber cloth. The shipping envelope was a simple pickled plastic bag without any rigidity. This worries me as the ring may have been bent in transit. Luckily mine wasn't like that and fit my lens and filters easily. Given the nature of the shipping packaging and the lack of a housing, this should be a concern for any photographer - personally I wouldn't want the filter thread on an expensive filter to be damaged, or the filter thread on an even more expensive lens to be damaged because the ring was bent or damaged during shipping will, and the rest of the product. The seller/shipper should consider more secure packaging: either add a hard plastic holder (one who can use Breakthrough Photography for its ND filters) or send it in a sturdy packaging. box, not a flimsy envelope. Do not get me wrong. the step-up ring itself is very well thought out; Just be careful when flashing for the first time. If it runs smoothly, everything is fine.
