Day 259 and I was taken by the sunlight falling on these trees in front of an empty office block close to West Croydon Bus Station.

EXIF info omitted from earlier post.

Panasonic DMC-G3
Lumix G Vario 45 - 200 f/4 - 5.6
Focal length 84 mm (168 mm equivalent for 35 mm)
1/320 sec
f/8
ISO 160

Did you set it to auto ISO? 160 is a bit odd.

It's base ISO on the G3. I've shot quite a few of my PAD images at this ISO, so it's strange that you have only just noticed!

Generally I only go after the ISO info when I'm not sure what settings you'd have used to achieve a given effect

What was the effect in this image which prompted the interest in the ISO setting? I only ask as there was a bit more PP than usual with this image as I had to get things straightened up in LR.

If I'm being honest, the windows (upper right in particular) looked "noisy" and the leaves in the centre were blending into each other. I wasn't sure if it was jpg artefacting from the file size or perhaps ISO. After seeing 160 I'm pretty sure it's jpg artefacting but seeing 160 piqued my curiosity

Actually, you are right. I have looked at the original Raw and the converted PSD and the latter does show some texture which is not present in the former. I think that what has happened is that this is a plain area which is slightly out of focus and processing the image in SEP2 has introduced some minor artefacts.
