Unfortunately, what you wrote is the sort of thing that confuses people.
85mm or 86.4mm is the same as far as making an image goes.
Yes, it makes the view angle the same.
And what I wrote makes the other image shaping aspect of lenses, the DOF, the same. Oh, and the light that hits the sensor also. Nothing confusing about that.
f1.2 is f1.2. It is NOT f3.24.
Yeah. And 32nn is 32mm. It is NOT 85mm.
But you know that but you want to add to the confusion, right? Yes, the dof is f3.2 but the lens is still an f1.2 lens. No need to multiply it by 2.7.
The lens is still 32mm, right? No need to multiply by 2.7.
I don't have the AW lenses but to suggest that the 30-110mm is “fat” really shows the effect of fake news.
Is "fake news" your new hobby horse?
The J5 is easily the smallest 1 camera and yet the 30-110mm is more or less the same width as the body. Remember, this is like a 80-300mm lens.
I once had the Sony NEX-5. You would be horrified how “fat” the 18-55mm kit lens is.
You just do not want to understand it on purpose. With the 1 lenses I mentioned, ithe relationship to the barrel diameter and the optics does not make sense. That is what I mean by "fat" and what makes them bigger than necessary, and visually unappealing. Which apparently all did not help with selling the stuff.
