Your 18-55 will suffice but you should also definitely get on of those Rokinon 12mm.. it's cheap at around 350$ and will help you in your landscape shots.
I have both. The 18-55 gets used when traveling and during the day.
The 35 gets used in low light or when I want to get a bit better image quality.
I don't have the 23 1.4 but I would love to have it. Then maybe my 35 would get less action, but then again maybe not.
I find IBIS to be useful for snapshooting, not for photography. When I make a photograph, I use a tripod.
There are a few lenses that are stabilized and do the work. For snapshooting, the 18-55 gets the job done.
Glad to see Zone AF is finally working! On my X-T1, the only AF setting that works relatively ok is Single Point.
Isn't there a bigger zone area than 3x3? Like 3x5 or something? Why 3x3?
Nice shots by the way! Are you following the World Cup? Go Team Canada hehe
I second that. Anything that requires an update in our lens system will be a downer. I don't mind update the camera but I've just switched from Canon to Fuji and I won't be investing anymore on another lens system for many (many many) years.
