I like how you caught the bee in flight in the first photo, but these seem kinda out of focus...... use a macro lens for shots like these. Not a telephoto.

Thanks for your comments. I know one of the problems for these shots is focus as I'm not using a macro lens (I don't have one yet...) Any good recommendations for macro lens for the XT? I'm currently looking at the 17-40mmL lens from Canon.

Have a look at the new EF-S 60mm macro from Canon. Played with it in the shop, seems like a cool little lense for doing just what you need.

Thanks. Will do some research on this new EF-S 60mm macro lens from Canon. However, I have done some researching before and people generally don't like EF-S mount as it's limiting in the future. What do you think?
