Pentax Japan has added a teaser on its main page that indicates the digital version of the Pentax 645 is close to being unveiled. Pentax may make an official rollout at the upcoming Japanese CP+ industry trade show, which starts March 11. The 645D would be Pentax's first true medium-format digital camera.

Hmmm! Sunt tot felul de speculatii, pe forumurile Pentaxienilor se discuta multe, dar.....

Da, si pe dpreview :
http://www.dpreview.com/news/1003/10031002pentax645d.asp
Din pacate cam scump (9 400$).
Si nu e "full frame 645" (cum speram eu, cel putin...)

Nici restul producatorilor nu fac senzori cu adevar de format mediu, adica 6x4,5. Se lauda doar cu senzor format mediu, dar nu corespunde filmului.
Nu spera inca senzor full medium format caci va mai dura pana atunci si va si costa...
Cat despre pret, ti se pare cam scump? ieri s-a lansat noul Mamiya digital, acelasi senzor, dimensiuni, MP si costa 22.000 in loc de 9400.
tot ti se pare cam scump?
Un full frame DSLR, iau cazul nikon, e 27000 de lei si pentaxul asta ar iesi la 28000-29000. mi se pare nesemnificativa diferenta de pret, gandidu-ma la diferenta de senzor si ce inseamna aceasta.

Kodak a avut pe vremuri un senzor la 16mpx. "full frame 645".
Scump fata de estimarile initiale citite pe net - intre 6000$ si 7000$(ca utilizator de Pentax 645N urmaresc subiectul de mult).
Probabil pretul e coret si menit sa faca fata concurentei.

Alea erau estimarile "visatorilor doritori"!

mie mi se pare ca 10.000 $ fata de 22.000 face bine fata concurentei.
O fi avand Mamiya obiective mai bune..dar si pentaxul are obiectivele vechi foarte bune. si pentru 10.000+ $.. prefer un obiectiv mai putin sharp.. teoretic. Daca ar fi sa ma iau dupa carcotasii ce se uita cu lupa la poze...

Oricum noi vorbim ca sa nu ne apuce plansul.
Cine naiba are 11.000$ (ca sa inceapa joaca pe MF) in Romania?

Si site-ul dedicat Pentax645D:
http://www.camera-pentax.jp/645d/top.html
Din pacate in Japoneza...
Sunt si cateva exemple("impression" si apoi la profile-urile din dreapta, pe pana), dar la 2mpx...
Site-ul nu-i inca terminat.
Probabil s-au grabit sa anunte oficial aparatul ca sa dea o lovitura concurentei (Mamiya, care tocmai anuntase propria noua camera digitala MF) si n-au apucat sa finalizeze site-ul.

Au sectiune dedicata pe Pentax Japan:
http://www.pentax.jp/japan/imaging/digital/medium/645d/feature.html
Anuntul a fost planificat pentru CP+ (ce ocazie mai buna?), iar sectiunea de pe Pentax Japan a fost pe picioare la timp.
Asteptam insa poze full-res facute cu acest aparat. Japonezii au avut ocazia sa admire o serie, tiparite la dimensiuni apreciabile.

Intrebare... 645D are motor focalizare si in body ?
Vechile ob.FA 645 din cate stiu nu aveau morot AF in corpul obietivului, nu .. sau ma insel. Daca 645D nu are motor in focalizare in bosy si nici vechile FA 645 nu au in corpul lor .. atunci doar cu ob.de 55mm recent lansat 645D poate focaliza automat.

Obiectivele FA 645 au motor de focalizare intern.
Aparatele (toate modelele Pentax 645) nu au motor de focalizare in corpul lor.
Noul Pentax 645D poate face autofocus cu vechile obiective FA dar, in mod ciudat, noul obiectiv de 55mm pentru 645D poate fi focalizat doar manual pe vechile aparate Pentax 645N si NII.

Nu stiu daca ati observat in link-ul asta o imagine a unei vitrine:
Lens lineup gallery. Nu mai putin de 15 obiective noi, inclusiv un super-tele. Shocked
Stiti ceva despre asta?

Nu exista deocamdata decat un obiectiv nou (DFA 55-ul) si un prototip (superangular, nu stim inca ce focala sau deschidere maxima a diafragmei va avea). Restul sunt obiectivele vechi - majoritatea autofocus - de pe vremea aparatelor pe film.
Cred ca obiectivul alb (supertele-ul) este A*645 600mm f/5.6 - deci cu focalizare manuala.

Da, acel cuplu exista si la Pentax 645N si pare a fi cuplu de AF.
Iar cuplul-mama exista doar pe obiectivele FA si nu pe cele A(manuale).
Pana acum nu l-am observat.
Cand faci autofocus tot zgaomotul se aude in obiectiv si nimic in corpul aparatului. Din cauza asta puteam sa pun mana in foc ca motorul e in obiectiv si nu in aparat. Acum nu mai sunt sigur...
N-am gasit nici o referinta despre modul de autofocus la Pentax 645N si nici in instructiuni nu scrie nimic.
Oricum... obiectivele FA fac autofocus pe 645D iar 55-ul digital nu face autofocus pe 645N. Asa scrie producatorul.

cateva concluzii se pot trage ... asa ca ramane la latitudinea fiecaruia daca isi doreste, are nevoie si isi permite o asemenea camera Smile
