After reading the ML dual iso topic, I thought I'd post a comparison from a single exposure shot using my new Sony a7r. All processing, including noise reduction was handled in Photoshop CC's camera raw editor. For me, I believe the sensor in this camera will severly reduce the need to shoot sets of multiple exposure bracketed images in the future.
This image was shot using my Sigma 35 f1.4 lens at these settings: f2.2, 1/4000th @ iso 100.
