Which lens for Canon EOS Rebel T3
I got some gift cards for Christmas. I do mostly travel photography (often from a moving vehicle) and for that I usually use the 18-55 mm lens that came with the camera which says 0.8 feet or a quarter of a meter (0.25m) If I am on a boat and taking photos of the shore from a distance (or for any other time when I can't physically get close to my subject - wildlife etc.), I have 75-300 zoom lens which works well for me. I'm not really interested in taking videos - I can never remember how to do that so I will default to my iPhone if I want a video.
I have always sort of wanted a macro lens although I do not know how much I would use it. Ditto the kind of lens which lets you take photos of buildings without them looking like they are falling on you. (Wide angle???).
When I look on the internet for a macro lens I can't tell from the description how close I can get (or how much I can magnify) the subject. It doesn't seem to be the millimeter number. What does that number tell you - just how physically long the lens is? Is a lens with only one mm number one that does not zoom? I assume the f-stop number indicates the amount of light setting.
So assuming that I have determined that the lens will fit my camera, what should I look for?
