Presentata la Canon EOS 7D, la DSLR “Hi-End”
La Canon EOS 7D fa il suo debutto ufficiale di oggi accanto a tre nuove lenti.
Il cuore della Canon EOS 7D è un sensore da 18 megapixel, CMOS e formato APS-C. La EOS 7D non solo è una potente fotocamera, ma assottiglia il margine tra fotocamera e videocamera: offre registrazione video in formato Full HD 1080p.
I pixel di questa EOS 7D misurano 4,3 micron, mentre il sensore è stato migliorato per migliorare il rapporto segnale-rumore. Grazie al doppio processore DIGIC 4 sarà possibile uno scatto a raffica fino ad 8 fps, mentre l’otturatore, a magnete rotante è garantito per 150.000 scatti.Sulla parte posteriore della macchina troviamo un LCD da 3,0 pollici ed un mirino al 100% di copertura. I pulsanti presenti sul retro hanno una disposizione alla 5D Mark II.
Sulla Canon EOS 7D troviamo in più un interruttore posizionato in alto a destra, per commutare tra il live view e la modalità di registrazione video.
A sinistra invece è presente un altro pulsante: touch-raw + jpeg.
In aggiunta un’ulteriore tasto, programmabile, che sarà personalizzabile in base alle esigenze personali.
Caratteristiche Principali della Canon EOS 7D:
- Sensore da 18 MP APS-C CMOS: Progettati e prodotti da Canon, il sensore produce un’immagine eccezionale e offre prestazioni fantastiche sia in condizioni di alta che di bassa luminosità, grazie ad un fotodiodo nuovo e la costruzione di microlenti.
- Scatto a raffica fino ad 8 fps: Grazie al doppio processore “DIGIC 4” e ad sistema elettronico migliorato, i fotografi possono acquisire immagini a 8 fps, senza la necessità di ulteriori accessori in ogni formato di file.
- Range ISO: La EOS 7D consente ai fotografi di catturare soggetti nel loro luce naturale. La gamma ISO (100 – 6.400) è espandibile fino a 12.800.
- EOS Movie: La modalità filmato rende semplice girare filmati in full HD, a 24 fps.
- Doppio processore “DIGIC 4”: Grazie all’elettronica migliorata ed al doppio processore DIGIC 4, i fotografi che useranno la EOS 7D non dovranno mai scendere a compromessi tra velocità di scatto, la qualità dell’immagine e prestazioni ISO.
- Design: Canon ha ascoltato i commenti dei fotografi durante la progettazione del corpo, offrendo ai propri appassionati il massimo.
