Lens Kit for Olympus Tough TG-7 TG-6 TG-5 TG-4 TG-3 TG-2 TG-1, Conversion Lens Adapter + 40.5mm UV Filter + Lens Cap, Replaces Olympus CLA-T01 Lens Adapter Converter

This works well as long as you're not intending to take it into the water. The ring does not provide a waterproof seal so water does get behind the filter causing droplets to form or fog to develop behind the filter. Totally useless once that happens as you need to remove the ring or filter to clear it.

This fits perfectly. The lightweight, durable plastic is good and will protect the lens.

レンズカバーが欲しくて探していましたが、ちょうどよいものかあり購入。水につけることはほぼないので、この組み合わせは大変良いと思います。レンズ保護とカバーがセットのものは最高です

Nice to have the lens covered with both an extra lens and a cover. Truly a cover should have come with this camera! I have never bought a camera that the lens was not protected in some way. This does the trick.

I purchased in part to provide lenses protection for my TG-7 and also to hold other 40.5mm filters, which it does. However, if you're expecting quality or a precision fit look elsewhere. The bayonet locks in place on the camera with a fair amount of play. it probably won't fall off but doesn't inspire confidence. The ring is made from cheap plastic and the screwing on the alloy filter proved tricky. Great care and multiple attempts were required to avoid cross threading. Given I expect to be changing out filters regularly I suspect I will tire of this hassle quickly I certainly won't buy again and will be on the outlook for something of better quality.
