Attention Photographers - it works well for Small Lens.
on November 6, 2012
This jar opener works well for only small sizes of lens (Regardless of the misleading product photo showing 3 openers and I ended up received 1). I'm using a sigma 50mm lens with 77mm diameter, I was able to fit the opener around the lens but that black plastic grip simply won't go down to tighten the lens. Therefore, focusing is poor and the opener kept falling off. I think it works best for lens that has 60mm or smaller lens size.
Also if you are using the Canon 50mm f1.8, the focus ring of that lens is way too close to the edge, the opener won't grip it at all. Just FYI. Hope it helps.
