The Doors

I have a collections of doors pictures... I generally take the historical places' doors or so fancy and majestic doors... This one is neither historical nor majestic... Just lovely for me... And wanted to share with you... Doors mean a lot for me both metaphorically and when thinking about their owners... I would like to buy a camera,which one would you advise me? You are all great photographers and sure you know which one is the best for macro photos...
