the Canon EF 50mm f/1.8 STM lens can be considered as the modern (and improved) version of the classic "fifty" lens from the Japanese photography company. It is a product that can be considered an entry level for all those who abandon a compact camera and begin to immerse themselves in the world of Canon brand reflex cameras. The reasons for the success of this lens are different but can be traced back to the fact that it costs little, has good brightness and ensures excellent quality shots and footage. One of the main features of this lens lies in the possibility of performing a very smooth motorized manual adjustment when the sector is set to MF and which does not affect the focus when it is instead positioned on AF. The STM motor it has allows rapid focusing as long as the subject is framed the first time. Another advantage of the Canon EF 50mm f/1.8 STM is its lightness and compactness and the maintenance of an excellent standard in terms of sharpness and colours. The entire body, including the ring, is made of plastic, which means that its weight is just over 150 grams. The presence of Canon's Super Spectra coating is very important, allowing it to reduce glare and the so-called ghost effect. Ideal for use in low light conditions thanks to its high focal aperture, it can be considered a lens that should never be missing from the photographer's bag.
