2.8 vs F4

[SJTstudios]

Here is a fun little topic, yesterdayI caught my friend and he caught me saying 2.8 and F4.

It's a bit weird, most photographers call regular # aperatures Fx, and all aperatures with a decimal, just the #?

Some examples
-1.2
-1.4
-1.8
-f2
- 2.8
-f4
-5.6
-f8

Please evaluate on why you think this is, or correct me if you don't.

If you asked me what aperture I used for my last shot, I may have replied, "A value where the ratio of the apparent focal length with the lens focused to infinity to the physical diameter of the iris diaphragm was equal to two point eight, when rounded to the nearest tenth unit." But maybe I just replied, "Did you like the picture?"

I think i'd respond to this if i had any idea what you're talking about

Using the whole number sounds like you're judge at a diving competition. It just doesn't have much relevance. The 'point' however puts it into photography context.

There's always 2.0 as in my favorite new lens! (135 f/2L)

Is it like freeway numbers? Take the 55 to the 5 to the 10 the 15 to the 395 or take CA55 to I5 to I10 to I15 to US395. :-X

You left out the 405 to the 101 to the 170 to the 118 to the 210

Dude this is like the 10th vague, unnecessary, and/or incoherent post/poll you've posted today, what are you trying to accomplish here?

He's making conversation, relaying an observation about photog jargon. I understand precisely what he's saying, as do several others here, and I've made the same observation as well.

What are you trying to accomplish by trolling his post?

 

[TrumpetPower!]

I'm more likely to leave out the "point." Thus, it's "eff two eight" and "eff four." I don't think I'd leave off the "point" for bigger apertures, though...it'd be, "eff five six," but "eff one point four." Not sure why.

For me it is clear too, what he ment.
I think, when a photographer sais "I shoot at 2.8" it's clear, that he is talking about the aperture. When he would say "I shot at 4" it could still mean, 4seconds or prob. 1/4 of a second. So we all say "F4". But normally we would also say f2.8, but we are all lazy

No harm no foul axil. You're smarter than that to rag on him about this with your over 1k posts.

 

[risc32]

okay,i think i understand what you're saying. yes, i do the same. I would say "2.8, and f4". it just seems to make things clear. if i just said "4", that could mean "4 seconds", or "for" or "four". never really noticed it.

 

[Jesse]

I say 4.0

Photog A - "Whats your aperture?"

Photog B -"Eff zero point seven"

It's actually "ditto", see this definition.
