Hi Tim,
The issues were mainly JPEG related.
The focus was very shallow so pictures had very limited sharpness. I was having real trouble dialling this out. I have now realised that was me restricting the ISO too much. The last two days have been quite dull and so restricting between 100 - 800 was expecting too much with the lenses I was using.
Second issue has been with reds. Taking pictures of red flowers outdoors and loosing almost all detail. This appears to be due to the custom image settings. Using the FLAT mode appears to have fixed this too.
Re-setting and starting again has helped a lot. Only alteration I have made thus far is the remember menu setting
