DSLR vs. phone at low light?

OK I will make a guess, but even the larger size image is still too small and low res to tell anything for sure. Is this a 100% crop - or was the image resampled? For a fair comparison, we'd need to see the full size images as they came out of the camera or phone. Also for a proper comparison both devices would need to be set to the same ISO, aperture, and shutter speed - or all bets are off.

My guess, for what it's worth [and that's not much], is that the one on the right exhibits horrible chroma noise in the shadows - and it is blurry, so I'd guess it was the phone.

But it is possible to get blurry images with horrible chroma noise on a DSLR, if you are clueless. Shooting with too high an ISO, or touching the camera to take the exposure could easily result in a poor quality image. Also, for all we know, you could have a crap lens, or a crappy filter on the lens. There are too many unknowns for a proper analysis.

Update: and fhotoace is right, the one on the left has the wrong white balance.

Update 2: - even if both are ISO 1600, you still are not comparing like with like unless the shutter speed and aperture are exactly the same. Also shooting with an ISO of 1600 is pushing it with a DSLR, since the usual method of getting more light with a DSLR is to open the aperture, using a faster lens, or longer shutter speeds.

Update 3: For comparison, this is a 100% crop from an APSc sensor camera, it suffers none of that fuzziness evident on the image on the right, or any chroma noise. Also shot at ISO 1600, and a small amount of NR http://i.imgur.com/yo9dCje.jpg - shot across the street from me, the building is a harbour warehouse, lighting is from light above the door and others around the harbour, other than that it's pitch dark. Distance 150 yards approx, focal length 55mm, f/11, shutter speed 1.3 seconds, tripod, wireless remote. Canon EOS M mirrorless. EF-M 18-55mm lens.

Wow!

If you can take that left photo with a phone then you don't need a dSLR. Good for you! It's a matter of skill. I admit I can't make a phone take a photo as good as a dSLR but that's because I can make my dSLR take a better shot than that left photo.

The right-hand image is horribly noisy and not at all sharp. If that *is* from a DSLR, you should junk that camera. Definitely looks like a phone photo.

My guess is the left is DSLR, right is phone. The resolution in the left image is better. Noise in the right image is higher and noise reduction is overly aggressive.
