If you read every post, you need the 15/21/35/70. At that point the 40 is good enough to add in as a one-lens option for casual shooting. Of course you’ll want the 20-40 in reserve for those times that one lens isn’t enough but you don’t want to carry a bag. And then SMC is better than HD for starbursts, but the HD Limiteds have rounded blades, so you’ll need both coating formulas for the 15 and 21. At that point, WTH, the used SMC lenses are so inexpensive, just get two complete sets.

The real story is the 21/40/70 kit covers most prime lens needs. The 15/4 is really a specialty lens that you’ll want if you’ll use it. Likewise the 35 Macro is a special use lens that punches above its weight. It isn’t so much what you ‘need’ as whether your goals require the properties of the 15 AND the 21.
