Having said that, there is no grammatical or usage rule that specifies how acronyms should be pronounced, and there are acronyms in common usage everywhere pronounced either by letters or the word. Typically, acronyms that have an awkward or meaningless pronunciation as a word are referenced by their letters (e.g., NCLB for the "No Child Left Behind" Act), as opposed to a word pronunciation such as "mad" for MADD (Mother's Against Drunk Driving).

I-S-O or Eye-so works either way, hence the variation.

Having started in photography back when it was still ASA, I've always pronounced it I-S-O. However according to the organization themselves, it should be pronounced like a proper name ISO (eye-so). That doesn't mean I'll be changing though. See here for more info.

Actually, it isn't. From your screenshot the acronym should be IOS.

From Wikipedia:
"The three official languages of the ISO are English, French, and Russian.[3] The name of the organization in French is Organisation internationale de normalisation, and in Russian, Международная организация по стандартизации. According to the ISO, as its name in different languages would have different abbreviations ("IOS" in English, "OIN" in French, etc.), the organization adopted "ISO" as its abbreviated name in reference to the Greek word isos (ἴσος, meaning equal)."

Around here, I have never heard any one pronounce the abbreviation as eye-so, it's always been I-S-O.
Just like I knew it's predecessor as A-S-A, never as Asa. DIN however, was always pronounced as Din, never as D-I-N. (Man, am I dating myself with that one, or what?).

No Problem, seems like most here are over 50....and some go above 80years of age.
...remember when ASA was 400 max....now they are going into the stratospheric numbers which really makes no sense to me ......Probably should be switching to some other name and scale !

Trying to make the English language make sense is a foolish thing. The language is full of silly things. Please explain to me how you can get soaking wet when the rain keeps up. And you can get killed when the gun goes off. I say tomato.

My first camera (Zeiss Ikon Contessa) used DIN. At around 7 years old, I had a hard time grasping the fact that my dad's Nikon was set to ASA 200 and I was using the same film set to DIN 24.

Once you get by the fact that things don't have to make sense, things are easier to understand

I.S.O. is not a word so should not be pronounced as a word, just as U.S.A. is not pronounced:"yousaw."


Very good and apropos!

Funny how this can lead to other subjects. I have mow learned that ISO is not really an acronym; it is an initialism. I have always spoken each letter separately, as I always dead with ASA and DoF. But if you want to keep using "I-sew", "ace-ah" and "doff", go ahead; I know what you mean and will not complain.

Just do me one favor. Stop saying that ASA and ISO are the same things. Up to a certain point, the values for film/sensor sensitivity are the same, but ASA values do not go as high as ISO values, and the numbers are from different organizations.

We have (in the UK) a military group called the 'S A S' . Three distinctly separate letters. Nobody would ever refer to the members as 'Sas'. Well not more than once anyway. I was always brought up referring to film speeds, as I S O...or A S A. Three separate letters, just seemed natural, because one knew what the letters stood for.
