I've read over a few of the macro posts on this site, and I'm very new to digital photography, so I have a few questions, and some may be overlapping. I have a Canon EOS Rebel T3, and I want to buy a macro lens. I want a 1:1 ratio, and so apparently my cheapest option for such lens is $574? Or actually there's this one for $449. My question is what's the difference between these 2? Is it only the 100mm and 60 mm difference? And what does that really mean? Does that mean that with the 100mm I can be farther away and take the macro shot?
This is a pretty big purchase, so I want to make sure if there's anything I should know about macro lenses before purchasing one. Honestly I dont know much about what aperture or ISO or about different lenses, I just like taking nice pictures, and I do plan on learning all the advanced stuff, but I really want to take macro shots.
