Just a word of caution. Be carefull with the Harbor freight o-rings, they are not a standard size. I have measured several of them with a digital caliper and they do not measure the same as several known good ones or the spec chart. They all seem to be of a smaller cross-section, there not as thick so they may not seal as well.

Just F.Y.I

Most modern cameras, particulary SLR cameras have built in meters that are as accurate as you would like, particularly for reasonable exposures (not sunballs for example). I have a meter and play with it because I like playing but the pics I get with it (both in the studio and UW) are not any different than without it.

True, but so did my Nikons. The meter allows you to meter different areas and to set exposure without having to look into the view finder. I can alos place my palm in front of it and use it as something of an incident meter for a generic exposure. I find it very useful even for cameras with an on board meter. As well, many cameras have different bias, spot, center weighted, averaging, bottom weighted, various computer digital programs, the good old Sekonic, once you are used to what it is telling you, never lies and you can use that information to second guess your camera's meter.

O-rings can be gotten many places, I only suggested Harbor Freight because they have many cheap kits of various types and compositions. The Sekonic door uses a fairly thin O-ring, at least my two do and it was easy to get another O ring that worked well. YRMV

Harbor Freight Harbor Freight Tools - Quality Tools at the Lowest Prices

sells a kit of o=rings made in china and they are not as thick as standard o-rings.

measured harbor freight spec o-ring #
.068----------.060-----.070-----017
.102----------.091-----.103-----112
.137----------.122-----.139-----214

Note that these measurements do not coincide with standard metric o-rings either.

There non-standard o-rings, close but I wouldn't use them in my reg's or camera gear. I wouldn't trust my life or money on them but there ok for some uses.

Many thanks Bill now we all know not to buy O-rings for expensive dive gear from this place.Buy U.S.A.made!!
