I've had a massive dry spell recently, despondency has been my middle name with regards to photography. Where I live now just doesn't do anything for me photographically, however after sorting out a photobook I decided to get out there again (my file manager suggests the last time I went out was february, when I went on holiday!). Most were terrible but I came across a nice little Dandelion and decided to spend some time with it....
Taken with a Sigma 24-70 f/2.8 at f/14 and a set of manual extension tubes. It appears f/14 at this sort of range (the front lens was around an inch from the dandelion) causes one heck of a lot of CA, even ACR couldn't fix it fully!
There's one or two other possibles from the shoot but this is definately the pick of the bunch.
C&C welcome

The extension tubes he's talking about moves the lens further away from the sensor creating the illusion of a 'macro' type lens from an ordinary zoom lens.
