lenses, but how many are there? How to use them as appropriate? What features have?
These are some questions that a person who looks at the photo you might ask. First, we can make a speech on general mm characterizing certain types of lenses:
- from 12mm to 28mm wide-angle lenses we have, that family of lenses that we need to photograph landscapes or scenes such as wide-ranging
- from 36mm to 50mm lenses instead we have "normal", which broadly reflect what is the vision that we look to the naked eye a scene and are used for photo reportage, documenting scenes of everyday life for example and to hear , "inside" the scene viewer shooting
- we go from 70mm to 200mm telephoto in the field of medium, ie those goals that are used to photograph distant subjects on average to enlarge or to take portraits in a discreet manner without being subject to him
- from 200mm up to canvases are proper, dedicated lenses such as photographic or hunting to resume, however distant subjects, an example is the "guns" that you see on the sideline during games to Football
addition to these objectives there are some details on the features such as fisheye, 8mm objectives covering a 180 degree view, similar to that of fish and which allow even imaginative shots.
Other specialized lenses are those called MACRO, do not have a defined length, there are 35mm, 50mm to rise at will and have the peculiarity to retrieve items with magnification factor of 1:1 and to focus a very low distance, are useful for photos to insects, such as flowers, the whole world "small" we often pass by without we see it.
Each lens also brings with it its own problems, virtually the only free, they are "normal" because require very complex optical patterns than others.
wide-angle lenses, for example lead to a curved edge effect, more and more pronounced as they descend with mm and becomes a big flaw if you photograph buildings, for example, because the lines are curved strange.
The telephoto lens instead lead to a "flattening" the image that may or may not be a defect in the second frame and the subject while the macro lenses are usually very defined and if used for portraits may pull out even the smallest blemishes.
To assess the quality of a lens should be analyzed one thousand factors, not only has the brightness seen as aperture, each lens has a soul that moves to the next step. No, not crazy, just make the windows go in a different light, may provide more or less detail, make it softer or harder, and even photos in color can be special.
juggle How so?
The forums are a mine of information to draw on, you can hear opinions to see sample photos and talk to those who have a specific lens to hear what we can tell. Eye, however, usually those who spend € 1000 for a lens will be unwilling to criticize just to do the figure of the fool then always seek partners critics, who exalts the merits only, who does not find defects is never a good adviser for all that is made carries with it some damage, if only the building itself 'This objective can not convince at all.
A tip, forget the reviews, there have been few series as well as sites that specialize in reviews, unfortunately, like all businesses they receive bribes in the form of advertising and certainly will be less critical of those who allows it to exist rather than to others.
Another advice, it is difficult you can find a good lens at a low price, especially in new business then you are using Keep in mind that if you just paid a little wrong translated as meaning that only need to buy expensive lenses, but that expectations should be proportionate price.
Last thing, if you have a limited budget to start would be best to choose a less expensive body and invest now in a good light because this combination of economic effort will pay off if you do the opposite and only you will be disappointed.
