EXIF Focal Length Format

Good job. guys. thank you!!

It's much, much better now.

But I would have inserted a space between ISO and its value.

That's why I said it looks very much better now.

First things first, I think the new EXIF labeling is a big step in the right direction, but there are some points I’d like to make.

Here are my points:
1. There should be a space between the units and the numbers: 16 mm, 1/170 s (see section 5.4.3 in The International System of Units).
2. (35mm eq. 24mm) is very odd. For two reasons: the two numbers / distances have very different meanings and why not include an equivalent for the aperture?

I’m okay with point 1 because the space beneath the photos is limited, but I think it would be good to promote the use of the space in other places.
As for the point 2, I really don’t like the 35 mm name. I also don’t like FF, but in this case it could be better (and shorter too). May be someone would come with an even better suggestion. A new symbol, perhaps?

As for only including the equivalent of the focal length, well, you certainly have thought about it and it is true, I believe, that it is what most want. I don’t have any problem with that either. If there is some sort of instructions to the forum it would be nice to explain that focal length and aperture are properties of the lens, that the same values create the same angle of view and gather the same light per the same area of the sensor no matter what the sensor size is. On the other hand, if you want equivalence for the whole sensor both parameters need to have different values.

I will end with a comment on being “pedantic”. If I write “Here i am” anyone would say the “i” should be capitalized (even the spell checker does) and no one would be called “pedantic”. Unfortunately, that’s what happens when talking about math or other science rules.

Oh dear, I've been here in the USA too long, duh. One of my favorites here as an engineer used to be gas mass flow in MMSCFD (millions of standard cubic feet per day).

I like that rhetorical question!
Maybe too late but I still dislike the so-called 35mm equivalent number - and yet there are indeed many who apparently can't function without it! ...

... I don't much like "crop factor" either, grump ...
