How do you say the aperture of your lens? Do you always use the same nomenclature when describing it or do you say 'One-Point-Four' and 'Five-Six' (i.e. it changes)?
The point is practically necessary. Otherwise 1.4 could be confused with 14, etc. It is more important if the radio reception is not the best and when working in a multilingual/multicultural environment.
I say one point four but may say one four at times... If I did say one four I would say "wide open at one four" or "open all the way up to one four".... come to think of it the only one I usually remove the point from is five six...
EB-1 I see your point..wow...you must shoot in some very serious conditions... j/k
I usually say "Eff (number) point (number)", but when I talk fast, or very repetitively, or to someone who I talk to a lot about photography, I will sometimes say "Eff (number)(number)", as in "yeah, the eighteen two hundred is a three five five six lens", or "the eighty four hundred is slow not only because it takes 2 days for its Aye Eff to lock onto something stationary, it's also only four five five six."
However, I don't think I do that for apertures that are larger than f/3.5, so for f/2.8, or f/1.4, I would always say "Eff one point four", never "Eff one four".
