Not got many examples of using it in super low light, just been looking through and found these 2 in moderately dark conditions.
First one is ISO 800 in a dark alleyway, some pretty extreme dynamic range at work here but there was plenty in the raw file to work with,
The next is the interior of a church shot at ISO 1600 and looking back a much too slow shutter speed of 1/10, I could of opened up the lens to f2.8 or gone an extra stop of ISO to get a more usable shutter. But if you ignore the slight blur I think you will agree its not a bad effort. This is probably a good advert for the 3 with its SR mind, but I got the shot and the alternative would of been a phone camera which would not of done well here.
I have used higher iso's in darker conditions and am happy with the results, not shared any as though technically fine they just weren't good photos.
I am happy with its performance in the situations I have used it in.
