My X-E1 vs D7100 High ISO comps

What\'s the dynamic range like at base and low iso?


It\'s very good actually. Here are three exposures; the first is at Base ISO (200), the second at Base ISO underexposed by 4 stops and pushed 4 stops in LR4, and the last at ISO 3200. The IQ delta between the second and third demonstrate the base ISO DR (shadow noise) and color fidelity retention, which depicts DR and ISOless\'ness of the sensor.

Here are three 100% crops of an 8MP downsampled image from each of the 3.

Crop #1 (Left is ISO 200, Middle is ISO 200 4-stops Underexposed, Right is ISO 3200)
Crop #2 (Left is ISO 200, Middle is ISO 200 4-stops Underexposed, Right is ISO 3200)
Crop #3 (Left is ISO 200, Middle is ISO 200 4-stops Underexposed, Right is ISO 3200)

Here are the D7100 equivalents, but pushed 5 stops instead of 4 (ISO 100 -> 3200 on the D7100 vs ISO 200 -> 3200 on the X-E1)

Crop #1 (Left is ISO 100, Middle is ISO 200 5-stops Underexposed, Right is ISO 3200)
Crop #2 (Left is ISO 100, Middle is ISO 200 5-stops Underexposed, Right is ISO 3200)
Crop #3 (Left is ISO 100, Middle is ISO 200 5-stops Underexposed, Right is ISO 3200)
