Why use a Zoom Macro?

Good and bad points …

First, despite what the manufacturers lenses may try to sale, there is no real Macro Lens. Traditionally, macro lenses are lenses that provide a ratio of 1:1 or higher magnification. This means that size of the object is the projected size in the film or sensor … To view, you can think of filling his entire frame of 35 mm with an average size of the room. This macro. Macro lenses do not zoom. Some Zoom Lenses allow more than the average distance of approach, creating a quasi-macro "situation that lens manufacturers are quick to call the macro. This may be appropriate to take pictures of flowers or large creatures, but not (in itself), arrives to take these pictures insects, raindrops or crazy … etc. Today, some macro lenses first reach even 1:1, but require components Further, such a converter "size" for access to this increase. Just because you do not have a true macro lens, does not mean you can not do macro, however. There are a number of tips for using the macro increase in other macro lenses. Two of the most popular are the use of extension tubes that go between the lens and the camera and extend the distance between the rear of the lens the film or sensor, and close-up lenses that screw on a filter. In general, the extension tubes is considered the best option in terms image quality, and that does not add another piece of glass in the equation. Thus, because it could make a macro "target" using zoom extension tubes (for example), I can not imagine it extremely useful. PRIME LENSES generally offer better image quality at a given focal length, which is essential when you are trying to capture fine details. In addition, the depth of field becomes smaller than one approaching an object, and the frequency with which it is actually razor DOF end. Therefore, the macro is usually done especially with the approach manual, even if the lens is AF. Thus, the ability to adapt quickly by zooming (instead of positioning a mobile) is relatively ineffective because fire must be carefully prepared anyway. generally encourage new macro photographers examine one of the major manufacturers or third (Sigma, Tamron, Tokina) macro lenses of about 90mm to 105mm. All offer excellent picture quality and good value for what you get. This zoom range will give you a lot of work remotely if you get scary bug hunting, and since these lenses allow infinity (normal), Focus, serve excellent Portrait Lens.
