Switched to my FujiFilm 18-135 with my new X-H1 toy about a week ago and cannot put it down.
What a camera! What a lens. Couldn't be more satisfied.
Thanks to Uncle Kenny Wheeler for his accurate reviews of both. "When He Talks, I listen"
The 35 1.4 was my first lens when I went into the Fuji system in 2012 or '13. To this day I still say: "you'll have to pry my 35 1.4 from my cold dead fingers". I also owned the 56 1.2. I bought it for a particular shoot. I had three back to back portrait sessions in a beautifully lit church. Big windows down the sides, gorgeous skylights, just wonderful afternoon light streaming in. The 56 1.2 REFUSED to lock focus on my subjects most of the time I was using it! Very frustrating and embarrassing. I wound up putting it away and using my 18-55 and my 35 1.4 and successfully finished my three back to back shoots. That was on a Sunday. On Monday I returned the 56 1.2, and eventually I wound up with the 60mm 2.4 macro to replace it. Now, the 60 2.4 isn't the fastest but what I purchased it for, macro work, it was fine. BTW I was shooting the event with my X-T2 with what at the time was the latest firmware in case you were wondering.
That's my background with my entry into the 56 1.2. It's a beautiful lens but just not for me.
In Fuji, I presently only have primes, by far to date my most used lens has been the 23mm f/2 but if I were to get one it would most certainly be the FUJIFILM XF 16-55mm f/2.8 R LM WR Lens (24-84mm, 35mm Equivalent) is a zoom range that would work well for me and the f/2.8 would be nice for low light.
Here are some test shots of flowers taken with my X-T1 and a modified vintage 1970's Helios 44-2, 58mm lens at f/2. I love the old Helios lenses as portrait lenses too. I keep a couple unmodified versions on hand for more general use.
