It doesn't take much to make for a reason to switch lenses.
A slightly different angle of view is only part of it.
There is the whole feel and balance and style of image that the lens
produces. A lens "of a different color".
High or low speed and compactness.
Macro or infinity orientation.

Typically there is a 10 to 15 point spread between basic focal lengths.
35 to 50
50 to 90
8 between 90 and 135
9 between 24 and 28 (Nick the Greek said 10)

But between the 75 and 90 there is only 4!

There was a day when I worked intensively on my white backdrop changing back
and forth between my N's 85 and 105mm. And that's only a 5 point spread.
Made all the difference in the world to me. Enough to interrupt a shoot to
change a lens or switch bodies.

But simplified when I went Leica M 12 years ago and the 90 did the jobs of
both!

It's easy to think that they wanted a high speed short telephoto.
Call it super high speed because to many an f2 90 is a high speed lens.
I do.
And a 90 f1.4 just specked out too big and heavy.

Rolleiflex TLR people get all excited about the different things they use
their 75 for and the things they use their 80 for.
