Hey gang, I just bought a used Nikkor 55mm Micro and PK-13 extension tube off eBay. I am so psyched: 1:1 macro photography. Does anyone else on APUG have experience with this lens or Nikon macro photography in general? Does anyone have the bellows attachmnet? Can you offer me some advice, etc.? Any links I should check out? Ara Ghajanian Just as a silly nostalgic side note: Does anyone remember that National Geographic publication for kids called "World"? (Yes, I grew up with National Geographic in the household... what a nerd.) On the back cover of every issue they had a feature called "What in the World?" which was basically extreme close up photos of every day objects and you had to guess what each one was. I was always inspired by that feature and now I want to try just that: extreme closeups of every day objects. Anyways... what a nerd.
