mike_young1 Posted March 17, 2007 Share Posted March 17, 2007 I recently added a Tamron 28-75mm lense to my xti. This lense is called a macro by Tamron. I also own a Canon 100 2.8 macro lense. Can anyone tell me on what basis Tamron calls the 28-75 a macro lense? Link to comment Share on other sites More sharing options...

jimstrutz Posted March 17, 2007 Share Posted March 17, 2007 Lies, damn lies, and sales talk. It is generic sales speech for any lens that focuses close. It doesn't even have to be all that close. In reality, "macro" is a term that has lost it's meaning by overuse and misuse. Link to comment Share on other sites More sharing options...
andrew robertson Posted March 17, 2007 Share Posted March 17, 2007 To a lot of people a 'true' macro lens is one that achieves at least 1:2 magnification. Link to comment Share on other sites More sharing options...

stephen_w. Posted March 17, 2007 Share Posted March 17, 2007 I agree with Andrew 1/2 magnification, which means one may photograph an object of 72mm onto 36mm of film or more diagonally. 1:1 is life size on film. Link to comment Share on other sites More sharing options...
