Red White Hibiscus

I decided to go to the Botanical Conservatory today. They had lots of beautiful orchids and hibiscus wish I could have stayed longer to get some nicer shots. I had one issue though my 300D is having a hard time focusing. I thought it was just one lens that was the problem while in Portland but nope I can't get any of my lenses to focus right I tried my 100 macro on my mom's camera she had no issues with it so I tried her 100 mm macro and well same issue. I'm hoping to take my little rebel in to Focal Point to get it cleaned and figure out what is wrong with it. I tried my best at manually focusing but my eyes aren't perfect so I can't tell if the shot is going is going to be dead on clear like I want it to be. I was going for trying to get the stigma and stamen to be tack sharp but hehe its still off.
