Beginner photographers often wonder how important the sharpness of a photograph is. It is difficult to answer unequivocally. If you answer in terms of a technically perfect shot - yes, sharpness is important. Even if a photograph is artistically ideal, but significant elements are blurred, then it is suitable only for an amateur album, it is unlikely that such a masterpiece will be able to boast. But in the opposite case, a technically perfectly executed photograph with sufficient sharpness, but without artistic design, loses not only its attractiveness, but also the meaning of existence.
With sharpness is inseparable concept GRIP... Grip is the depth of field, which is the amount of space that remains in focus. Fluff depends on focal length and aperture.
Sharpness is considered by many to be an overrated concept. Newbies and seasoned photographers often test their cameras and lenses extensively, combining them in different ways to achieve perfect sharpness in different conditions. Thanks to their efforts, there are many tables and computer programs that evaluate sharpness. This is especially true now, in the era of digital photography. Images on any lens are viewed pixel by pixel: resolution at the center, at the edges, at the corners. But is a camera bought in order to photograph tables and test sharpness? Perhaps this process is better left to theorists, who like the process of finding the truth more than shooting.
Summing up, we can summarize: sharpness is an essential component of a high-quality image, but you should think about it when everything else does not cause difficulties or doubts.
Nevertheless, lens selection Is an important matter. Some models will not allow sharp pictures at all. For example, a budget ultrazoom like it... High-quality optics cannot zoom more than 3 times. The exception is Canon EF 28-300mm f / 3.5-5.6L IS USM. Considering its cost, weight and dimensions, it is better to think about something else. Prime lenses are optimal in terms of sharpness. The budget Canon 50mm 1.8 at closed apertures will outperform much more expensive optics in sharpness, for example, Canon 24-70mm 2.8L USM... The choice of focal length is another matter, but this is a topic for separate article.

Getting the sharpness you want isn't really difficult. You just need to practice and be careful. Beauty and artistic sense are another matter. Not everyone can achieve a clear idea, let alone find it at all. Those who still have interesting ideas in stock, but cannot achieve sharpness in photos, should stop blaming the equipment. As a rule, it is not his fault, but the negligence of the photographer himself. Modern cameras have a fairly high resolution, and a large number of megapixels allows you to detail the smallest details of the image. This should be taken into account - the higher the resolution of the camera matrix, the less chances of mistakes and inaccuracy for the photographer.
