I ordered the mask for my girlfriend who is near-sighted. She gave me a copy of her prescription. Under the "Dist" part of her prescription, sphere is -8.5 which is the number I used when I placed my mask order. I am assuming "DV" is distance, and "NV" is near. If so, I believe you would enter the "DV" number. The mask worked great for my girlfriend. She said she could see better out of the mask than her glasses. Hope that helps, Brian H.

Hi Alexander, I think "OS" stands for "One Size" as in one size fits all, but in this case I don't think so. It is a nice mask from all the ones I've used for lap swimming but they don't give enough length on the adjustable straps. I don't want to discourage you from purchasing the mask, first see what the return policy is and if there is no extra charges on returns give it a try. Happy swimming!

Michael - Thank you! Thank you! Thank you! I just educated myself on the 10-22 mm and decided that is the lens for me! Now to save up... :)

It is the 2 LX. The model is the LX and this is the 2nd generation of that model. I've been diving with U.S Divers gear since the 80's and I really like this mask and snorkel.

I recently had cataract surgery and I am now farsighted. Standard 5X magnification didn't help at all, so I went for the highest one I could find. If a 5X doesn't work at all for you, go for the highest magnification.

Yes nv stands for night vision. The two nv settings give you a very light sight picture to work in conjunction with any night vision system you have, so your reticle isn't blinding you. This sigh alone will not provide you with night vision.

Yes, somebody here said +.2 or something like that.It is minor but present; makes screen seem just a little bit bigger.You can get them as prescription lenses if you need more.

If I understand your Query correctly you need to wear reading glasses. Correct? The EOS Canon cameras have a pretty extensive range of adjustability built in. If you need something additional (rather unlikely) then match the diopeter number to the number you wear with your reading glasses. Such as +1.5 or +2.5...I purchased this adjustment lenses but actually found out the Canon had the correct adjustment on the camera for me around +1.75. So I don't use this piece.

I would just love some sort of estimated date. Just be up front with us, even if it is a month off. I ordered the black 12-50mm kit. The sad part is, I see so many people getting them from local dealers. The ONLY reason I ordered from Amazon is because I had a really good gift card balance. If I could cash out my amazon gift card balance and go to a local dealer I sure as heck would in a heart beat~

There is two ways of getting your S/N#: (1) On the len's focus ring, you will see "A009N-xxxxxx" (just on the left of MAKE IN JAPAN"). P.S. The xxxxxx is etched onto the lens. (2) The S/N# is on the top left corner of the original tamron box. It is kind of big. P.S. I have to cut it out from the box in order to get the current $100 rebate from Tamron. If you cannot find it, you should bug the seller on why. May be it is gray market, or second hand. Good luck.KC

I am so accustomed to wearing a snorkel, I haven't noticed that it impairs vision at all. I wear goggles every swim so, I would say its safe to wear a mask.

The "Telephoto Lens" that came with this package is a "Vivitar Series 1 - High Definition 2.2x58mm" with the number 1090413 on the lens itself. Maybe I am stupid but I do not know what IS means. On the folded paper that came with the lens, which is the "user guide", there is nothing on the paperwork that would indicate IS, whatever that is.

I think -4.0 and -4 are the same. If you are near-sighted, you should choose negative.

I don't own an SX, but the filter size is typically written on the front of the lens. Should be a number followed by a circle with a line through it. If it says 58, you're good to go.

hi, none of us are opticians. I'd give them a call and ask. That way you'll get a pair of goggles that you can use to read underwater - haha - but seriously, I was thrilled when I could see clearly underwater. It's worth the effort!
