\"\"<\/a>Au jeu de celui qui poss\u00e8de la plus longue, je suis le plus fort. Cela cacherait-il un besoin de compensation docteur ? Apr\u00e8s avoir cass\u00e9 ma tirelire<\/a> pour un Nikkor 200-500 mm \u00e0 5.6, je me suis lanc\u00e9 dans la photographie des oiseaux qui vivent au bord du Rhin. Tenue de camouflage, bottes, monopod, si\u00e8ge pliable (cadeau de No\u00ebl), me voila d\u00e9guis\u00e9 en parfait p\u00eacheur, sauf qu’en guise de canne, je trimbale un gros objectif tr\u00e8s lourd. Mais m\u00eame d\u00e9guis\u00e9 ainsi, je ne suis pas un hobbit<\/a> et les volatiles me voient arriver \u00e0 des kilom\u00e8tres. Salle b\u00eates… Quand je suis sur le point de shooter, elles s\u2019envolent, taquines les bestioles. Alors je me suis dit, si je ne peux pas me rapprocher, je peux peut-\u00eatre ajouter une loupe sur l’objectif. Cela s\u2019appelle un doubleur de focale, \u00e7a co\u00fbte un bras et vous fait perdre deux diaphragmes. Pour tester la chose, j’ai choisi la version du pauvre, un Kenko Teleplus MC4. Evidemment \u00e0 ce prix l\u00e0, la compatibilit\u00e9 avec la gamme Nikkor est tr\u00e8s partielle, par exemple vous perdez l’autofocus et la stabilisation sur la majorit\u00e9 des objectifs. Mais le 200-500 mm, devient un 400-1000 mm \u00e0 f 11, c’est \u00e0 dire en r\u00e9alit\u00e9 un 1400 mm vu que mon Nikon n’est pas un plein format. Mettre le Kenko sur un Nikkor 200-500 mm, c’est un peu g\u00e2cher de la belle optique et revenir \u00e0 la mise au point manuelle avec ma vue d\u00e9faillante. C’est retrouver les gal\u00e8res du Samyang<\/a> (1 photo correcte pour 10 rat\u00e9es). Mais \u00e7a marche. Evidemment, la lumi\u00e8re vient \u00e0 manquer (f 11 pensez-vous), il faut tenir l’ensemble avec souplesse car sans stabilisateur, une focale de 1400 mm \u00e7a donne le mal de fleuve. Le temps capricieux ne m’a pas beaucoup permis d’essayer le tandem pour l’instant mais je compte bien le tester \u00e9galement avec la lune et le boudoir de ma voisine.<\/p>\n","protected":false},"excerpt":{"rendered":"
