Am dubii. Nu ca Pentax n-ar lucra la un aparat "full frame", caci au declarat asta; nici ca n-ar putea sa apara un Pentax numit K-3 - ci ca zvonul e adevarat.
Ai putea preciza o sursa? Multumesc.

Adica asta:

Pacaleala de 1 aprilie - ala din 2012, caci mai sunt cateva zile pana la cel de anul asta.

Lansarea pe 27 martie e iarasi pacaleala, la fel si "hands on experience".

Daca ar fi o pacaleala, imi cer scuze pentru dezinformare.

Din punctul meu de vedere, problema e a site-urilor care preiau si raspandesc insistent asemenea facaturi; ele dezinformeaza. Este dificil sa faci diferenta, mai ales cand la o prima vedere suna plauzibil...

Oricum, full frame-ul vine; doar ca nu maine, n-o sa fie numit K-3 si n-o sa aiba specificatiile alea (doar din coincidenta).

Se zvoneste ca Rikoh-Pentax vor adopta tehnologia senzor-shifting pentru a realiza imagini de coalitate inca si mai buna. Tehnologia consta din mutarea senzorului cate un pixel in sus, jos, stanga, dreapta, iar cele patru imagini sunt combinate pentru ca fiecare pixel sa otina toate imaginile de culoare.

Este posibil ca chiar si unele modele aflate in prezent in vanzare sa poata dispune de un upgrade de firmare pentru implementarea acestei tehnologii.

Se zvoneste ca Ricoh ar putea renunta la productia de Pentx.
Ricoh a achizitionat Pentax in 2011, care detinea locul VI pe piata mondiala de camere foto.
Vanzarile de camere digitale in 2016 au fost doar o cincime comparativ cu anul 2010 si de o zecime comparativ cu 2008.
