I imagine quite a few of you have seen the Petapixel article about the 'star eater' behaviour in Sony A7RII 3.3 (and A7SII 2.10) firmware.I have also observed another undesirable attribute of this behaviour -All taken with Pentax HD 35mm adapted to Sony. Camera set to Uncompressed RAW. All NR/Steadyshot settings off. Remote release and MF used for all images.All settings between the images identical except for shutter speed and exposure adjustment in post.I shot the images 2 stops apart, pushed the 1.3s exposure up by a stop, and pulled the 5.0s exposure down by a stop.Original RAW of 1.3s image: https://www.dropbox.com/s/p050wp1wqof5nb5/DSC00139.dng?dl=0 Original RAW of 5.0s image: https://www.dropbox.com/s/i4d6pdpsd9g6bzm/DSC00140.dng?dl=0 Full Image:1:1 no sharpening1:1 with high sharpening2:1 with high sharpeningWhat you see is the squiggly watercolour effect that you usually get with high levels of noise reduction, there is also a noticeable drop in metamerism (colour differentiation).The same effect can be seen to a higher degree on images with finer grain (ie. rocks and sand).I have another example image here which displays very low resolution and micro-contrast because most of the detail is pixel sized and Sony has decided I don't need that.It wasn't a controlled test so unfortunately I don't have a shot of the same subject with a shorter exposure, so take it with a grain of salt.Full Image:No SharpeningHigh Sharpening
