The crop is pretty small here and if you like detail and have a fast connection, you might want to follow the link to Flickr and view it in the Original size. I really enjoy looking at bug and flower details that you can't see with the naked eye.
Using f/11 I was able to get around an inch of DOF, which is a lot for a macro. We've been talking about ISO here a lot and lots of people would have tried to shoot this at ISO 100, used a tripod and maybe shot at f/8 or even wider. This shows that noise is not a big worry. Yeah, a pixel peeper can find some noise out in the corners at the Original size, but no "normal" viewer is looking out there. What noise there is is not disturbing and it's minimized by exposing properly. Here I shot at +1/3EV and blew out the highlight in the eye, but no one cares but us photographers. I'd rather have the details on the bee and flower and control noise, but not eliminate it.

The Flickr full size is great and one day I hope to get something like that but they have to move slower and I have to move faster. I haven't thought about ISO with them with all the light. I'll use crazy ISO indoors to get the good exposure but don't think about that outside.
