I wanted to see the difference in the ISO capabilities and image
quality of the NEX-5 and NEX-5N, so I set up a tripod and shot a series
of shots from each in RAW+JPEG to see the differences. I chose a scene
in my house to show color reproduction and detail that also had some
straight lines to also show distortion from the 18-55mm kit lens. I used
Program mode and just adjusted the ISO. I left the lens at 18mm for each shot.
First, is the NEX-5's Auto JPEG. I corrected for lens distortion in Lightroom. The NEX-5 chose ISO 800, 1/30 at f/3.5.
Here's the 5N's Auto JPEG. I didn't have to correct anything since the 5N has built in distortion correction on JPEGs. The 5N chose ISO 2000, 1/60 at f/4.0.
Just to show the barrel distortion, here's the auto JPEG from the 5 without lens correction.
I did the lens correction for the remaining shots.
Here's the 5's Auto shot in RAW.
Here's the 5N's Auto shot in RAW.
ISO 100 JPEG from 5N. The 5's ISO sensitivity starts at 200, so nothing to compare here, but I just wanted to include it.

I hope this is helpful to someone!
I just want to take this opportunity to thank
Amin Sabet from the Talk NEX forums for the NEX-5N giveaway that allowed me to have the NEX-5N. I really love the camera and the community of those forums!
