I'm fairly new to Fujifilm. I originally had an old x100 but it was too quirky for me...but fuji was still intriguing to me. A couple of months ago I bought a used X-T1 and fell in love. It just makes shooting more fun for me. I started on Nikon, switched to Canon, switched back to the Nikon D750 last year...and now find myself switching over to Fuji for stills. I've been slowing phasing the Fuji into my weddings...the last wedding I shot was probably 95% fuji except for the few dancing shots I used a flash for. Really, my only hesitation has been the luxury of the D750 having dual card slots. While I've yet to have one fail, it only takes one to ruin a good chunk of a wedding.
Anyways, for my next wedding, I'll take my nikon stuff just in case...but plan on using Fuji all day. Here's my gear...
2x X-t1
Rokinon 12mm
18mm f/2
23mm f/1.4
35mm 1.4
56mm 1.2
90mm f/2
I just got a yongnuo flash/trigger set to handle my reception lighting...might even pick up a 2nd flash
The last wedding I shot with a x100t and a X-T1 mostly with the 56mm lens on it. While I really like the x100t, I sold it for another x-t1 because I like having my two cameras set up the same. The difference between the two were enough to cause me to fumble within the menu a few times. So this wedding I'll shoot primarily with the 23mm and 56mm...and use the 90mm during the ceremony
