Thought you all may be interested in seeing some super low light photos. I was using the 23 F2 but wish I had the 1.4 in this situation. (I used the 16mm 1.4 on the wide shots of the stages). I still think the camera managed the noise well. ...noise reduction in PS.
Low Light Festival Portraits
Majority of the photos were shot at 6400 and above. 1/3 of them were at 12800 - all handheld with no flash
Obviously they wouldn’t be good for printing but I think good enough for the web.
note: if you want to pixel peep first select the photo so it goes into the light
