It's interesting to see what focal lengths I actually use, the info in LR gives a great insight. With my zooms, I tend to use one end or the other. With my 70-200, I tend to use the long end a lot more. Which makes me realise that using primes of those particular focal lengths would be better really; as I'd have larger max apertures. Sure, zooms are useful, but mostly it's one extreme or the other. I think I could happily just have say a 24mm, 50mm, 85mm and 135 or 180mm, and not feel much loss. I would like the Z 85mm, as I love my old 85mm f1.8D, so that'll probably be the next Z lens I buy. The 14-30mm looks fun, but I had a Tokina 11-20mm lens on my old D3300, and tbh, only really felt the wide end was 'useful'. But then; you don't miss something until it's gone...
