This has been a DxOMark week - another set of test results were published today for the Nikon Coolpix A compact camera. The smallest APS-C camera today outperforms many other compact/mirrorless cameras and comes close to the capabilities of the D5200 and D7100 DSLRs in terms of high ISO and dynamic range performance. DxOMark's conclusion:
"The Nikon Coolpix A high-end compact offers similar or better image quality to many entry-level or mid range DSLRs, and although bettered by the higher resolution D5200 or D7100 DSLRs and the Pentax K-5 series, the Coolpix A still makes the top 10 for APS-C cameras."
