PossibleOff-gassing during storage in heat
Where these two actually differ
- We flag Polyurethane coating degradation and VOC release, Durable water repellent (DWR) chemistry unknown and Off-gassing during storage in heat on the Think Tank Photo and not on the B+W.
- The B+W is Optical glass lens with multi-coated optical surfaces where the Think Tank Photo is Polyurethane-coated nylon, DWR-treated, which is most of the difference in these two grades.
- The gap is 45 points, wide enough that this is not a close call, and the B+W is the one to buy.
- We are less certain about the Think Tank Photo grade, at 45% confidence against 82%, because it discloses less.
Both products run through the same public rubric, which covers materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
