Sony Alpha NEX-5R Digital Camera Review$749.99
You've got two options for how the NEX-5R handles noise, either leave noise reduction on the default "Auto" setting, or step it down to "Low" and force the camera to use less destructive smoothing at the expensive of more severe noise. According to our lab tests, these two settings are actually pretty similar. More on how we test noise.
The 5R sensitivity range is wide, extending from ISO 100 to 25,600 all in full resolution. Frustratingly, the camera will not automatically use sensitivities above 3200, so you'll need to be proactive about your ISO level in low light.
