Also Fuji users, I'm looking to upgrade to mirrorless soon. Currently torn between the X-T2/20 or one of the Sony A7Rs. What is the Fuji like at low light shooting without IBIS? Especially on holiday I do abit of night street shooting. I am a bit worried the body doesn't have IBIS and some of the lenses especially primes don't have OIS. DO you get a lot of missed shots or have to shoot super high ISO?
Thanks
Ben
Ben, IBIS has its uses, but if your street target is moving then it will result in blur in the image, which maybe your objective, but if you want a sharp image of a moving target you will have to shoot at higher ISO to shorten the shutter speed anyway.
The Fuji handlles high ISO well, as long as you have decent dynamic range in the image, not a black cat in a black hole.I'm quite happy in these sort of situations to set the upper reaches of my Auto-ISO setting at 6400, I'd rather have something sharp than blurred. On occasions ISO12800 works well. I have posted examples previously in this thread as have others. This is ACROS at night at ISO12800

One ace that the Fuji has up its sleeve is the ACROS film simulation, the processing of this Fuji have kept to thereselves, but they have hnadled the digital noise very well, so much so that it looks like film grain, rather than digital noise.
The later X-Trans3 sensors are much better at High ISO than previous sensors, so if night-time shooting is your bag then I'd recommend X-T2, X-T20, X100F or X-Pro2.
I've no real experience of the Sony, but being FF, the overall package is less likely to be as compact as the Fuji offerings.If you can live with a fixed focal length lens, then I would consider the X100F for street work, as its small and discrete.
