Canon EF 8-15mm L F4 Fisheye

Thought I would try and take some completely different pictures. I grabbed my 8-15mm L, something I usually don't do, and found myself killing 30 minutes at a park in bright sunshine with spring flowers coming out. I happened to have a 600EX-rt flash in the car so I decided to see if I could try some high speed flash sync straight into the sun to see if I could get any sun flare from some weird angles. I got down to ground level and shot up at the flowers, in portrait mode, trying to get the sun in the very top of the image.

The specs are: 5D3 @ 15mm, F4, iso 100, SS (1/1600 to 1/5000), 600 EX-rt on ETTL with various FEC, laying on ground shooting up. This is what I got.

Pictures are cropped by about 1/3rd for composition
