I only need a replacement for my Nikon 24-120 f/4 travel lens, which would be a 16-85 Fuji f/4. It would hopefully be sharper than the Fuji 18-135 lens.

Agree with milandro. I live in Thailand and travel quite a lot around the country. Though I like my 23 & 16-55 very much (maybe the 23 a little bit more), I end up using the 16-55 the most when I travel but the 23 mostly in Bangkok.

..or the new Rokinon 50/1.2? Manual focus though.

Over the last 3 years I went all-out on alternative kens hoods for my XF glass collection:

I use my X-T1 kit (23mm and 16-55mm) primarily for shooting pics of my family on outings and indoors. Even from someone coming from a pretty compact camera (Lumix LX7), I got used to the relative bulk of the X-T1/16-55 combo pretty quickly and don't feel as though it feels unbalanced, and I don't use any additional grips.  The ergonomics for me personally are very comfortable, and I don't have the largest hands.  The combination feels solid but not "brick" heavy.
 
I may have had a less than stellar copy of the 18-55, but I feel the 16-55's images are on a different level.  I'm just an everyday shooter who uses Fuji purely as a hobby, and my lack of skills probably has something to do with why I didn't feel as though the highly reputable 18-55 didn't seem all that fantastic to me, but I didn't change anything with my technique and still feel as though my results are dramatically different, despite what some review say regarding a negligible difference in image quality between the two.  The extra 2mm at the wide end is a nice bonus.
 
I personally don't mind the lack of OIS since I use it primarily for shooting people pictures. (It would have been nice to have of course and for others that use the lens in different scenarios, it could represent a deal breaker)
 
The lens is not as big in person as it may seem in pictures online, but it IS a big lens.  It makes for a combo comparable in size to your typical Nikon/Canon APS-C DSLR (like a 5300/5500) and telephoto zoom.  Rent it first and give it a try, though.  If you're contemplating getting one at all, you owe it to yourself to give it a go.  This is coming from someone who swore he would never tote around a DSLR-sized package to snap pics of family.

I am seriously considering the purchase of the XF 16-55mm f/2.8 lens and would like to know what the experience of forum members is with this lens.  I have read a number of reviews, but I would like to hear from users who are not professional reviewers.
