Une certaine passion de la photographie
D2h & D2hs
 


Beaucoup de choses ont été dites et écrites sur ces deux boîtiers Nikon que sont le D2h et son descendant le D2hs. Pour les avoir possédé tous les deux, je désire opérer une petite mise au point au vu des expériences qui m'ont été donné de réaliser. C'est le but de cet article qui ne fera que complèter ce qui peut être lu dans les diverses review et compte-rendus de tests publiés sur le net et dans les revues spécialisées.


Voici pour commencer des liens vers certaines de ces reviews :

Nikon D2H Review Test

Cette liste n'est pas limitative bien entendu. J'y ai placé les tests les plus connus, la plupart étant en langue anglaise.

Remplaçant du D1H de Nikon et sorti des usines en septembre 2003, le D2H a été revu de fond en comble, du boîtier jusqu'au système autofocus. Testé à l'occasion d'évènements sportifs, il s'est révélé impressionnant à de nombreux égards et décevant à d'autres. Le D2H est à la hauteur, grâce à une vitesse de prise de vues rapide, une ample mémoire tampon et la plus longue autonomie jamais offerte un appareil reflex numérique (dSLR).
C'est en février 2005 que lui succède le D2hs. Ce dernier apparaît comme une évolution majeure de son aîné, apportant des solutions réelles aux faiblesses de celui-ci.
