My new Canon 500D close-up lens just arrived and it seems that I'm going to have plenty of fun with it. I'll use it with my Nikon 18-200 VR lens, hoping that the setup will allow me to emulate a macro lens (without having to carry one, and without having to change lenses back and forth, thus protecting my sensor from dust). Hurried first photo (50% crop): I'm planning on driving 4 hours to the International Peace Garden this weekend, to shoot flowers (and maybe insects) with my new toy. Will I hit the ground running with this setup (superzoom + close-up lens)? Or is there a learning curve that I should be aware of before heading out? (Wouldn't want to come back and find out that all my images are blurred/out of focus/etc.) Is there anybody out there who could give me some advice? Your help is much appreciated.
