This is about as close as you can get
I had HDR turned on for this
Apple iPhone 5s
Has an 8MP camera with a fixed f/2.2 aperture
Low light with the iPhone 3GS to compare
You can see there's a big difference
Low light test
Compare with same subject taken with 3GS. The brighter lens of the 5s means ISO is 80 instead of 400.
Using a photo filter
Hi-res shot using Hydra app
This app has various modes for low light, HDR and hi-res. If you use a tripod and have a static subject, the results are extraordinary.
