I have an OlyE-510 with 2 lenses:a 14-42 and a 45-150. I have tube extenders that are mechanical so no feedback to or from the lens. I have been taking pictures with the 45-150 lenses with the tubes on it. This means I have only manual focus control. Shooting closeups of bugs is, well, almost an insane process. I am womdeing what is it that makes a true macro? Someone in this forum uses a Canon 60mm macro ad gets stunning results. Is a lense a macro because it is 28mm or 15mm? Or is a macro only possible with a "true" macros lens? I am wanting to fiure this out cause the time and frustration of manually doing macro photogrphy live is quite difficult on moving subjects. If I get a 28mm lenses will that give me more macro capability? As well as keeping the electronics working with the lenses? Thanks and thanks for the kudos forth featured member for my wasp pictures.
Actually it's a matter of math :) The term "macro" frequently gets used inaccurately, especially by manufacturers. True macro means 1:1, or "lifesize" on film. That means that the the subject of the photo is at least as big on the piece of film as it is in real life. The film is 35mm long so if you were to take a picture of something that's actually 35mm long it would fill the picture from side to side.
The standard Canon 100mm macro lens and Nikon 105mm micro lenses are true macro lenses. The Canon 65mm macro lens actually does a whopping 5:1 magnification.
If you shop for a real macro lens try to find the magnification in the specs. Sometimes the manufacturers don't list it, which is very annoying.
Adding extension tubes and extenders to regular lenses can get you close to 1:1 but it's unwieldy usually. There's all kinds of crazy things you can do to increase magnification- tubes, extenders, diopters, stacking lenses, etc.
I work with olympus 410 and use the zuiko-macro-lens 50 mm;
I think what makes true macro is the combination of a very sharp focus with a low F-number ( f. 2.0) so the center of the object will be as sharp as possible and the surrounding of the object shows a superb depth of field.
with this lens I use a teleconverter , that doubles the zoom, but makes the F-number a bit higher ( F 5.8). and I am truly happy with that combination... focussing is automatic with this combination of macro-lens and teleconverter.
and ... the zuiko macro-lens 50 mm is a very good lens... it auto-focus very sharp and quick
Dear Saguarosam, If you use your zoom 45-150 with a few extension rings you can be sure that you make good macro pictures. This combination allowes you to stay at some distance of the subject.
I have a Sigma 105 macro lens and mostly I work in manual focus mode because of the absolute correctness of focussing. A 180 mm macro lens is the best solution for insect macro.
Eccersizing and patience is the only way to be a good (macro photographer)
wish you success
