There is a lens for each photo. It has all happened to us that, after buying our first SLR camera, after messing with it for a while, we have realized that the objective that came with the initial kit does not cover ALL our photographic needs. And that's when we start asking ourselves, what would be the next objective that I would have to buy now? It must be said that this question, very successful and intelligent by the way, some ask it even before, just when you want to buy the initial camera / kit. Not having the slightest idea of what each type of lens is for , they do not know if a camera kit + 18-55mm lens is useful, or with an 18-105mm lens, or which one exactly. Today it occurred to me to explain in a simple and very simplified way, as always without going into technicalities or deep explanations, what type of lens is advisable to use for what type of photography .
BEFORE STARTING..
Although you do not want to use technicalities, the expression "Focal length" you will read a lot in this article, you should know what it is. If this is not the case, read this before proceeding .FIRST .. WHY A DIFFERENT OBJECTIVE FOR EACH SITUATION?
The answer to why there is so much variety of lenses is found in the compact cameras, those that have a fixed, unique objective, with which we try to get decent photos in all circumstances. We all know that while the quality of these photos is always acceptable, it almost never reaches the level at which a SLR camera along with its lens / lens can offer us. The variety in the objectives allows us a very high level of specialization. Each objective is good, very very good, in its range or in the type of photos for which it has been taken. Working all kinds of photos with a single objective would be cheaper, that is true, but it would be detrimental to the optical quality of the photo.FOR EACH SITUATION, AN OBJECTIVE ..
Then I will discuss the most common situations that you want to photograph and the type of objective you will have to use to get the best result. Go ahead that you can always photograph all situations with the objective, but what I propose here is the ideal use, the way you would get the best results. Portraits / Potraits: A 50mm lens is recommended here. Can you shoot a portrait with a focal length of 200mm? In principle yes, it could be, but the normal thing is to move between 50mm and 70mm as a rule, being possible to shoot at greater focal distances as well.Landscapes, nature, panoramas and urban scenes: For this type of photography you will need a wide-angle lens. They are objectives that can capture a wide angle (hence its name). They usually have a small focal length. For example, the typical objective that usually comes with SLR cameras, 18-55mm, is valid for this purpose, as long as we put it at a low value such as 18mm for example or around that figure. In fact, if we could achieve an objective with a smaller focal length even, for example 17mm, or 14mm there are, it would be phenomenal. As these objectives not only capture a panoramic view but, at very short focal lengths such as 14mm or 10mm, even produce a certain distortion in the objectives (landscapes, clouds, buildings, trees, etc.) conferring a touch of grandeur and magnificence. For portraits, another important aspect is the opening of the diaphragm. You will need a target whose aperture is large (value f / as small as possible). A f / 3.5 would be worth it, but if it were lower, even better. If you are passionate about portraits, if you think that most of your photographs are going to be portraits, then yours are the objectives of fixed focus. They are objectives where the focal length is one, fixed, does not change, always the same. There are two very famous and whose results in portraits are excellent and are 35mm and 50mm. I know and use Nikon's, but I know that Canon also has two similar ones. These objectives produce shocking results, first because they are fixed because they offer a higher level of specialization and their optical result is designed precisely for that specific focal length. On the other hand, these objectives usually have a VERY GENERIC aperture aperture, for example of f / 1.4, and with that the result of the portrait will be spectacular (If you are new to reflex photography Be sure to read this article that will guide you on how to produce stunning portraits in simple steps .) Sports, action, children: There are situations in which you have a telephoto lens with a focal length that goes for example from 70 to 200mm, or you go crazy. They are situations in which we can not get very close to the subject and in which we have to shoot the photo from where we are, for example watching a football game in a stadium, a motorcycle race, or even trying to photograph children (hyperactive beings and elusive by nature). In these cases we are interested in having a telephoto lens that reaches as much as possible, but that also offers us versatility to change from a long focal length type 200mm to a short one such as 60mm or 50mm for example without having to change the lens every little time.Macro: Macro photography we all like. We love to capture those little details that fill our daily life but we rarely pay attention to: skin folds, insects, tree leaves, rose petals, homemade objects ... Thanks to Macro photography, anything can become an attractive object. If you want to dabble in Macro photography, you have to do with a long focal length lens. For example, from 70mm up you can get good results. Also keep in mind that normal targets can only focus from a certain distance from the object, if you try to approximate more than the account they no longer focus. That is why there are specific objectives in the market Macro, made with the ability to focus very closely.
