Just Posted: Updated Samsung NX200 Studio Comparison (raw & JPEG)

UPDATE: Following the provision of Beta raw support from Adobe, we've updated our previously published studio samples from the Samsung NX200 to include raw files. Also, we've recently got our hands on Samsung's new NX 60mm F2.8 Macro ED OIS SSA and we've taken the opportunity to replace our existing samples with a completely new set, taken on the newer lens. In future, the 60mm macro will become our standard studio lens for the Samsung NX system. 

This is our standard studio scene comparison shot taken from exactly the same tripod position. Lighting: daylight simulation, >98% CRI. Crops are 100%. Ambient temperature was approximately 22°C (~72°F).
JPEGs are shot at default parameters and raw files are converted using Adobe Camera RAW. Because Adobe Camera RAW applies different levels of sharpening to different cameras we use the following workflow for these conversions:
  • Load RAW file into Adobe Camera RAW (Auto mode disabled)
  • Set Sharpness and Noise Reduction to 0
  • Open file to Photoshop
  • Apply a Unsharp mask: 100%, Radius 0.6, Threshold 0
  • Save as a JPEG quality 11 for display and download.
Note: After identifying an issue with image softness which affected images shot at a narrow range of shutter speeds, we have re-shot, and replaced our ISO 100-800 (inclusive) raw and JPEG samples.

Our ISO 100-800 samples were reshot using a neutral-density filter over our studio light, reducing the luminance of our test scene, and allowing us to use longer shutter speeds. This has produced slightly sharper results in the ISO 100-800 range. Our previous samples shot at ISO 1600 and above were unaffected by the issue and have not been replaced.
