Yes, genuinely torn here.
I'm beginning to see the zoom as more of a generally useful lens. The OIS, the reach and flexibility, the possibility of extension. It's still bright with 2.8 throughout and sharp.
Hitherto, in terms of use, I've tended to only love my primes... So far.
The 18-135mm I barely use. The 10-24mm is remarkable but I only have specific use cases, big skies or architecture...
On the prime side... my 35mm 1.4 is hardly ever off the X-T2 body and I love my 56mm, I use it intermittently but when I do, i am so glad I have it.
I've a feeling the 90mm might be as extraordinary as the 56mm but will only get occasional use.
Hmmm. On the other side of things, two good choices, no wrong outcome :-)
