Cheers PeteRob I suspect had I used my 60 or 100mm macro the flash would be underpowered, as it is, using the 35mm I was right up to the subject 2-3cm away at most, the ant shots had the lens touching the tree trunk. the little critters kept climbing onto the camera...shudders!! I love the texture of the snail, you can almost feel the moisture. That lens is a cracker, the IS coupled with the relatively short focus is brilliant. Trying to photograph the ants was so hard, I switched AF off, left IS on and rested the lens on the tree - but it was still hit and miss. I've really enjoyed doing this, I'm looking for earwigs..can't find any. Going to try my luck with spiders too!!
