A fixed lens for amateurs it has become an exception. And yet it is the best way to reconnect with the mythical photographers, Cartier-Bresson, Robert Doisneau and the other Jeanloup Sieff. It is the school of composition, perspective. We must move, think framing. It is the school of creation. We focus on the image, not the zoom lens of choice. Excellent apprentice to become again. The eye reclaims its rights and responsibility cowardly abandoned the zoom lens. An unbeatable value for money. An interesting dive. A maximum aperture invitation to the creative process, easy to master as with a fuzzy TV 300 mm. It's a game. A very decent autofocus, both fast and silent. Why miss what will become, like the 70 your basic objective, permanently riveted to your case? No hesitation, order it immediately to Amazon ...
