The 5R camera carries on the Sony NEX tradition of excellent photo quality.
JPEG noise profile
The Sony Alpha NEX-5R implements extremely good noise reduction and JPEG processing. In good light, JPEGs look relatively clean up through ISO 800 and are mostly usable up through ISO 3200. Detail degradation starts to become noticeable at about ISO 1600.
The watercolor (left) and illustration (right) Picture Effects are built into the F3, but Sony only makes them available as part of the (free) Picture Effects+ downloadable app for the 5R. They are nice effects, though.
