[Neoprene] I choose this 45 degree viewfinder because not always have plenty space to shoot being completely vertical. This viewfinder allows me to be horizontal and be able to shoot perfectly

[0.1 lb] Great service on the phone to B&H. Ordered the O-Ring for my new PT-058 (I always like to have a backup & tend to swap O-Rings on a day to day basis). It was an exact OEM product.

[Neoprene] This really is an amazing housing for the price. The first one I had I used I actually found in the basement at my parents house. It had been sitting there for 10+ years and I did a leak test, still worked, and I used it to do surf photography for the first time. It did eventually split open at the side, but I did catch it before going in the water. It lasted a good 6 months which was amazing because it was at least 10 years old. So I bought another one! I loved the second one for a long time and my mistake was leaving it in the car in the heat :-( It shrunk because it got too hot in my trunk, then when I put the camera in it, the housing was soft and the side split open. My fault here for sure. So I bought another one, hahahaha :-) Moral of the story here is to just continuously do water checks for your housing, it is soft housing so just be aware of not leaving it in your car for a day when you aren't using it, but this has been such an amazing an affordable option for me until I can buy a proper water housing. The only downside is it is too hard to change the settings once the camera is in the housing. So I use masking tape to keep my lens set at infinity, then I set my aperture and shutter speed depending on the light, sometimes auto if it's one of those days, and then just go for it! I have taken some amazing photos and love love love how much I've learned to get creative with my settings because of the restriction of being able to change it in the moment :-) It gets 5 stars because for a tenth of the price I get to create amazing photos and enjoy surf photography! I don't have to wait to spend 2500+ on a housing to do what I want :-) And as with any type of water housing, there is always a risk of ruining your camera. I already lost one camera to the sea :-) But the joy of ocean photography is so worth it so I'm willing to jump into the possibility of doing it again! I hope you enjoy yours as much as I enjoy mine!

[Neoprene] I looked for these on two or three other underwater camera/SCUBA gear sites with no luck. Of course, when I went to B&H, they were available.

[0.1 lb] Light weight and easy to use. I started using it with my Canon EOS10D and am still using it with the EOS 50D. With all other housings I would have had to buy a new one each time I changed the camera...

[10 x 6 x 0.1"] As billed. Good quality o-rings with excellent quality lubricant.

[0.1 lb] Nice original part for the Olympus PT-058 housing.

[0.1 lb] Solid, light and impossible better constructed. Easy to handle and use. Superb materials

[Neoprene] Recently I ordered this o ring as a replacement to my PT-059 Housing for my TG-6 Underwater camera. I use the camera for photos of shipwrecks and dive sites when I travel. This o ring worked perfectly (as it said it would) and was tested to 40 feet at a dive site in Tobermory Canada. Look forward to stocking up on more. Fast shipping and handling especially to Canada. Don’t buy from somewhere else, trust BH Photo Video for your photography needs!!!
