Sony A7R II: Long Exposure Examples at ISO 100, Including Raw Conversion and RawDigger Exposure Info

Get Sony A7R II at B&H Photo.

This test assesses noise performance at ISO 100 with three examples at 30 seconds and one example at 15 seconds.

Sony A7R II Examples: Detailed Look at Long Exposures (Hoover Wilderness)

These examples are a good complement to the substantial underexposure in the Long Exposure Noise Reduction on/off at ISO 100 example, together providing a more complete picture of the noise performance out in the field for real-world images, where exposure is sometimes near-optimal and sometimes just reasonably good.

Analysis includes RawDigger histograms and ACR conversion settings for each. Includes mages at sizes up to 24 megapixels, with several large crops for each.

My aging eyes could not see color in this sky and only general countours in the foreground, but the A7R II pulled out a nice image. This image utilizes the entire dynamic range of the A7R II.
