Miscredenti ecco avevo annunciato tempo fa anche la pentax economica che arriva a puntino per il photokina. A breve arrivera' sicuramente anche la comunicazione ufficiale dei ragazzi della protege che ci tengono ben informati. E' una digitale con stesso sensore stesso pentaprisma e tante stesse cose della *IST D.

Solo con qualche tagli al software (manca ad esempio il formato TIFF) ma anche qualche miglioria.

Mantiene un grande vantaggio le forme compatte e la compatibilita' con praticamente tutte le ottiche a baionetta pentax K-, Ka, Kaf. Il prezzo sara' paragonabile a quella della 300D che ha aperto un'era.

Assieme esce anche una nuova lente DA 18 - 55 mm lens
