We were comparing inexpensive Tamron and Canon macro lenses above so here are some pics with the Canon 60mm macro. This lens is small, inexpensive, sharp and can pretty much do it all unless you need a wider focal length.
That is a super cool photo. I would love to see that many otos actually school, and they must keep your glass very clean. The photo is a bit dark, but I think if you had bumped the ISO any more it would have become too grainy.

On this photo I would really appreciate critiques because I have been working with it in photoshop and I feel like it still needs something. I adjusted the color a bit but mostly added highlights and blurred the background. The left side isn't very important as I need to crop it to have it fit in the frame. It looks dark but if you click the full image bar it isn't. Thanks!
