Reasons to choose GR
Released in 2013, GR has about 371 mm² of sensor area, 16.2 MP effective resolution, and a 245 g body. Use these values to narrow the field, not as an overall image-quality score.


The GR has the larger sensor area. More area usually means greater light-gathering potential, though real image quality still depends on sensor architecture and generation.
These cameras were released 1 years apart. Consider sensor generation when comparing pixel metrics.
Amber marks the value that is generally preferable in this comparison context. It is not an overall camera score.
The GR has the larger sensor area. The GR has the lighter body. The NX30 has the higher effective resolution. The NX30 is the newer release. Also consider the lens system and subjects you shoot.
