You actually think that manufacturers are going to make every odd size a few people want? It’s very expensive to design and manufacture lenses. They have to know, or at least expect, that enough people will buy it. I’d you “find” that you need a lens that pretty much nobody else needs, it’s never going to be made. What if someone else “needs“ a 30-155 f 2.5, or a 40-170 f2? They should make those also?That's the problem with much of the photo industry today; so much choice yet in reality so little choice.
Say I identify that I need a 35-150 f2.8. Where are they? Or perhaps a 50-135 f2. Nope.
But here are half a dozen 70-200 f2.8, now just buy one like a good little consumer.
