I'm not sure if this is in the right forum, so please forgive my ignorance as I am a newbie to this board. My old camera was a Sony 828 which had a built in 18-200 lens. I just got a new Nikon D200 and using an 18-105 VR lens. It is working nice and I like the quality, but lacking the following functions: macro, zoom. I don't really want to change lenses too often (or at all if possible) until I get more familiar with this DSLR. I am looking for at least the quality of the clarity and sharpness of my existing VR lens. Someone advised Sigma as they have a 70-300 as well as a 18-300 lens which does have a macro switch. What this switch does, I do not know, but hoping it will let me get nice macro shots. I am not against buying the Nikon/Nikkor brand, but usually you are paying a premium for the name. I am seeking to spend about $300 for what I am seeking. Also, I am not limited to 300mm as it can be more, but preferably not less. On another board, it was advised I go to a camera store and try out the lenses, but before I do, I want to at least know 2-3 lenses for which to research to test. The types of pics I take can be found at http://phillydog.info/events/perfect and I have recently added to the Flora section (so you can see the Nikon pics). -ANY- help is appreciated.
