I truly enjoy your macros
I think I'm going to try macro again.
I know that not all lens say MACRO on them but I have one that does.
Maybe you can help me understand something I heard.
Just because it says macro, doesn't really mean it is.
I have a Sigma DC 70-300mm lens that has a normal/macro switch.
Can I really use this for macro?
I have used it before.
Just not sure

When zoom lenses have "macro" on them, they are close up zooms effectively, getting you nearer to the subject - but not in the same way as a macro lens does - macro lenses give at least 1:1 coverage - i.e. it's a life-size representation on the sensor. The zoom lens will not give you 1:1, though you could fill the frame if your subject is large enough.

You can fill your frame and the sensor but it would not be a macro image - it would be a close up image.

That said, many images are taken this way to get a macro-like result, but it's not a true macro photo.

HTH.

Paul.
