pentax XW double-coulant ?

Recommended Posts

est ce que les oculaires Pentax XW (focale < 14mm) sont double-coulant, de meme que les LVW ?
Je trouve ca bien pratique.

Sinon, je voudrais m'equiper d'un bon oculaire en 7mm, principalement pour du solaire en lumiere blanche.

Merci !

Non c'est une peu plus petit que du 2".
Par contre j'ai déjà vu des bagues qui permettaient de les transformer en double coulant... Faudrait chercher sur le net.
