I'm confused about the subject of macro. I just bought the Tamron SP 60mm F/2 Di II 1:1 Macro for $525.00 and I love taking close photographs with it using my Canon Rebel T4i. But, I don't understand how to explain what my Canon PowerShot G12 does in Macro mode that's so different. In playing with the G12, the only thing that I can tell that it does in Macro mode it does not allow the camera to focus to infinity. That seems more like a limitation than a feature. I can still take close up photos when not in Macro mode.

On the other side, the Tamron 60mm gets closer and larger, but can still be used as a portrait lens quite well. This lens cost as much, or more, than my G12 camera.

Many of the answers I found online require a PHD to understand. I would like to know what is happening with these macros. I know that's sort of general, but I also don't know where to start.

Thank you in advance.

A macro lens like the Tamron is designed to work from macro distances to infinity in one range. Some models may have a focus limiter switch, to save the AF from seeking the whole range if not needed. The focusing range from end to end tends to take longer on macro lenses than others.

I haven't used the G12 specifically, but with experience of other compacts which also have a macro mode, I think something similar is happening. In normal day to day use, the focus may be slow to go from one extreme to the other. So to work around that, they can put in a limiter to do one or the other. If you know roughly what range you're working in, setting the camera to that mode can speed things up a bit.

Geez, thanks. That's a lot simpler than the complicated web page I found.
