In the olden days, the 2x range was perceived to be more than sufficient. So, since you have a 35mm, the natural expansion would be 18 on the wide and and 70 at the tele end.

But that was for print. For high resolution digital, some prefer (fast) zooms, or a range that follows a 1.5x sequence. It is probably overkill, but it gives you an idea. The two most typical sequences are (were):

  • 18, 28, 50, 100
  • 12, 24, 35, 85

12 to 24 is a huge jump in field of view, and I don't recall many 12mm FF lenses.

Lens sets:

fisheyes @14&15mm, then 18/20/21, 24, 35, 50, 85, 135, 200 was a typical full set, dropping either end depending on the stuff you like to shoot was comon.

A more compact set was: 24, 35, 50, 85, 135.

Further minimized: 24, 50, 85, though you could pick the FL that you like,

eg. I like 24, 50, 100 & 28, 100 as compact travel sets.

The reality is that lenses wider than 24 was not comon, 28 & 35 were wide enough for most shooters, and 24 made most of the remainder happy, and only a few WA junkies went wider(incl. me).
