Thanks for all comments and David C's image by image critique.
I agree that 9130 is the strongest. Colour wasnt tweaked that much either. Its the old trick of using a water spray on a cobweb. Surprisingly I had to use ISO 800 @ F11 1/250s in bright sunshine and added a reflector and still alot of shots were blurred. However, I was using the Sigma at its maximum 1:1 and all of these bugs were no more than 4mm in size so its insanely tricky on focusing
Apart from the ant shot all were handheld.
The ant shot probably took longest to setup. I saw them coming up a strawberry stem to feed on flies so setup camera on tripod and had it parallel for best focus. However, they were too fast so had to use off camera flash to freeze their movement. That took ALOT of experimentation, holding it at different angles and different powers. I later had a great water drop under another stem but they wouldnt perform for me, I even managed to drop a few of them nearby and they walked away
Well the spiders are still there (on an allium head) so I may retry and hope to avoid backside syndrome
David C - Ive had the Sigma for years and bought it second hand and find it fantastic. Robustly made, easy to focus and its got good glass. I still remember the first time I used it and saw the world very differently.
). The bokeh around the edges is lovely but it impinges too much on the main subject for it to work.
