Resources for Photographers

My name is Roberto Sorin, I'm from Sibiu city, Romania and I'm a passionate photographer of nature.at present owning a FujiFilm X-M1 body with Fujifilm 35mm F1.4 R XF and his capabilities in nature are limited, so I want to buy a telephoto zoom lens for the next step in the nature photo. After long documentaries and analyzes I stopped at the Fujifilm 100-400mm F4.5-5.6 WR OIS XF to which I add FUJIFILM XF 1.4x TC WR Teleconverter.
