Nope...the multicoloured mottling on the petals particularly in the shadow areas....
That's noise OK.
Sometimes difficult to tell the difference between noise and texture but if it intensifies in shadow areas, then it has to be noise without even needing to see the subject. The electronic noise intensifies as the sensor is deprived of a strong signal by shadows. If it were subject texture it would be more evident in well lit and obliquely lit parts of the image.
Also I think it's exhibiting strong CA, witnessed by the dark lines where there is strong contrast, the boundaries between white/pinkish petals shouldn't show dark lines. This is where the quality of the lens is really tested. My 24-120 suffers badly in this respect. APO lenses are the only answer because they are highly corrected for CA and can cope the the junctions of adjoining areas of strong contrast but as you may guess with anything associated with top quality, they are expensive.
OK, the screensaver splash screen just popped up. As you can see this is a quote reply not a 'quick reply'. Also, I am editing my original reply, so it may be associated with editing a post, I have yet to understand why I don't see typo's in the text edit box but they scream at me once I hit the 'Post' button!!!
The average person viewing this image will love the detail and 'closeness' but unfortunately once you are aware of noise and CA it does spoil the image a bit, I suspect the yellow parts may be slightly blown out but let's not go there LOL.
