Images shot with the Sony A7 with the FE 35 mm 2.8 lens - impressive low light capability without a doubt. ISO ranged between 1000 and 2500. Apertures varied between wide open and f5/6; Some noise reduced in post. Still the sony turned out to very impressive when shooting in low light. Clearly the lens was an added advantage.
Images shot with the Fuji XT and the 56 mm 1.2 lens - pretty close to the sony when shooting low light and worked brilliantly even when completely wide open. ISO was set at 3200 for the first two images and 6400 for the latter two. I found there a reasonable amount of noise which I was able to reduce to my satisfaction using Lightroom. There is still grain there but not so much as to be too distracting.
All these images have been post processed to reflect my creative vision.
