Olympus E-P5 : sans doute le meilleur pour la stabilisation en mode video



La stabilisation de la vidéo est tout à fait bluffante, elle reprend et améliore le système IBIS 5-axis de l'OMD.
Blunty a réalisé un test avec un modèle de pré-série, toutes les videos sont fait sans trépied ni de steadycam.

Pas encore un concurrent sérieux au Panasonic GH3 ou autres DSLR, la compression du codec est en dessous, avec 28mb/sec.

Fujifilm : revue du X20 en anglais par le site RIFLESSIFOTOGRAFICI

http://www.riflessifotografici.com/prove-corpi-macchina/fujifilm-x20-test-completo.html

  • meilleur autofocus que son prédécesseur, le x10
  • viewfinder amélioré, plus précis
  • AUTO ISO

C'est plutôt la réactivité du X20 et l'autofocus qui est amélioré, la qualité de l'image reste comparable au X10.
Quant au mode video, il n'est pas abordé dans le test.

Olympus E-P5 : nouvel hybride format micro4/3 de la série pen

Il reprend beaucoup du célèbre OMD
  • écran tactile, avec possibilité de l'utiliser pour la sélection de la zone d'autofocus et aussi de déclencher la photo ('touch focus' et 'touch shutter')
  • wifi comme la panasonic GH3, avec possibilité de tout contrôler sur smartphone ou tablette apple ou android
  • flash intégré avec possibilité d'ajouter un flash cobra
  • système de stabilisation à 5 axes IBIS, tout à fait extraordinaire. diminue le flou de bougé en mode photo et permet un mode video sans tremblements permettant de se passer d'un trépied dans la plupart des cas.
  • par contre tout se passe sur l'écran oled, pas de viseur (ou en option : VF-4 viewfinder )

Panasonic : Comparaison du nouveau G6 et du GH2


Video de comparaison très intéressante entre le nouveau Panasonic G6 et le très célébre Panasonic GH2.
Le G6 reprends le capteur du GH2.
La balance des blancs semble différente
meilleure montée en iso avec le G6 d'après ce que l'on peut voir.
