Confused Fergus


I don't know if you are confused or not, but others might be, so I hope you will forgive this contibution.

The point made by kds315 and, indirectly, by patrickh is that some manufacturers misuse the term "macro". If you look at 3 current macro/micro lenses..

Sigma 50mm f/2.8 EX DG Macro

Tokina AT-X M35 Pro Dx AF 35mm f/2.8 Macro

Nikon 60mm f/2.8 AF Micro

then each of these reaches the 1:1 magnification ratio but does not go beyond that. In fact each of them operates in the "micro" region - the Sigma, for example has scale markings between 1:5 and 1:1. Presumably, Sigma and Tokina would argue that since they reach the 1:1 boundary they are entitled to call their lenses "Macro". Nikon, on the other hand, recognises that their lens operates almost exclusively in the micro region and names it accordingly.

The situation is even worse. Many manufacturers don't worry about getting even close to 1:1. So for example..

Sigma 17-170mm f/2.8-4.5 DC Macro/HSM has a maximum magnification of 1:2.3.

And there are very many other examples.


Hi John

Yes, I agree lens marketing has a lot to do with the confusion. Amongst all the lenses I have, not one is a true macro lens though a few are marked macro. But the term micro can also be confusing. All my lenses could be considered as true micro lenses or am I wrong. "Nikon, on the other hand, recognises that their lens operates almost exclusively in the micro region and names it accordingly." but they only apply the name to a few close up lenses (typically similar to those other manufacturers that wrongly call these lenses macro) , and not all of their non-macro lenses.

Hardly the first time marketing morons trumped fact, logic or truth.

Did you know that in the US the law specifically says that you do not need to tell the truth in advertising, except for drugs! There is a lawyer in Washington who has been trying to get the law changed for the past 30 years, but Madison Av buys its way out every time. Gotta love all those corrupt pols.
