E' arrivata! La nuova Sony A7s II ha lo stesso sensore fullframe da 12 megapixel del modello precedente, ma aggiunge stabilizzazione in-camera, video 4K registrabile direttamente sulla scheda di memoria, video full HD a 120 FPS e un corpo con migliore ergonomia e mirino. Sarà disponibile da novembre.

Il comunicato stampa :
Ultra-high sensitivity up to 409600i with low noise across the whole range
Wide dynamic range across entire ISO range delivering smooth tonal gradation from dark to bright conditions In-camera 5-axis optical image stabilisation for expanded shooting possibilities Internal 4K movie recording featuring full pixel readout without pixel binning in full-frame format Wide range of professional movie functionality including S-Gamut3.Cine/S-Log3, new Gamma Assist Display, enhanced Zebra Function, Full HD 120fps recording and 4x/5x slow motion recording and full pixel readout without pixel binning in full-frame format High-speed AF with enhanced accuracy in wide ranging scenes and advanced shooting functions
Sony today announced the latest addition to its award winning series of compact, full-frame ?7 cameras with the introduction of the ?7S II. Offering ultra-high sensitivity and wide dynamic range across the entire ISO range and 5-axis image stabilisation for greater shooting control, the ?7S II delivers stunning image quality for photographers who shoot in the most challenging light conditions. Be it the brightest of mornings or darkest of nights, the ?7S II enables new levels of photographic expression at whatever shutter speed you wish to deploy. The ?7S II also incorporates a host of pro-style movie functions including the ability to shoot 4K video with full pixel readout and no pixel binning in full-frame format, making it an extremely appealing proposition for photographers and videographers alike.
The ?7S II delivers an awe-inspiring sensitivity range of ISO 50-409600 , thanks to the combination of its 35mm full-frame 12.2 megapixel image sensor and BIONZ X image processing engine. The sensor optimises the dynamic range across the entire ISO range and broadens the range of tonal gradation in bright environments and minimises noise in dark scenes meaning that it delivers impressive results even in the most extreme conditions. The upgraded image processing algorithm of BIONZ X maximises the sensor's capabilities and improves depiction throughout the full sensitivity range with particular emphasis on the mid-to-high range. This means that the resulting stills and movies demonstrate extra-fine detail with minimal noise.
Video Master The ?7S II can record 4K movies internally in the XAVC S format meaning that content is wonderfully detailed. Because information from all pixels is utilised without line skipping or pixel binning, the camera can maximise the expanded power of the full-frame image sensor and produce 4K movies with higher image clarity and negligible moiré. Full pixel readout without pixel binning is also employed when shooting Full HD movies which means that it collects information from approximately five times as many pixels that are required to generate Full HD and condenses the information to produce extremely high quality movies.
In a first for the ?7 series, the ?7S II can record 120fps at 100Mbps with full pixel readout without pixel binning in full frame format which can be edited into wonderful 4x/5x slow motion footage in Full HD. The ?7S II also has the ability to shoot 4x/5x slow motion footage internally which can be immediately reviewed on the camera screen.
Video functionality has been further enhanced with new profiles; S-Gamut3.Cine/S-Log3 and S-Gamut3/S-Log3. These new profiles deliver wide dynamic range and colour correction is easier to perform. The ?7S ll even offers impressive 14-stop latitude in the S-Log3 gamma setting. The camera also supports S-Gamut/S-Log2 which is very popular among cinematographers and videographers. Gamma Display Assist is a new function that allows users to monitor images or check focus when recording S-Log movies and the Zebra function has been improved for even greater control.
5-Axis Image Stabilisation The new ?7S II is equipped with the innovative 5-axis image stabilisation system that is proving extremely popular in the ?7 II and ?7R II cameras. The system corrects camera shake along five axes during shooting, including angular shake (pitch and yaw) which has the greatest impact on image quality and tends to occur with a telephoto lens, shift shake (X and Y axes) which becomes noticeable as magnification increases, and rotational shake (roll) that often affects night shooting or video recording.
Autofocus accuracy The autofocus system on the ?7S II has been upgraded and now offers 169 AF points for fast, precise focusing with greater accuracy. The power of the image sensor means that the absence of noise in images generated, enables the Fast Intelligent AF to detect contrast more easily and react speedily even in low-light situations (as low as EV-4), when it's even tough to check with the naked eye. When shooting video, the AF performance is twice as fast as the predecessor model.
Electronic Viewfinder The XGA OLED Tru-Finder in the ?7S II has been upgraded and offers the world's highest viewfinder magnification of 0.78x (roughly 38.5 degrees in diagonal field of view) and shows clear images across the entire display area. The use of ZEISS T* Coating ensures sharp reduction of reflections on the viewfinder and unlike an optical viewfinder, the OLED Tru-Finder can be used to instantly show how exposure compensation, white balance and other selected settings are affecting the displayed image.
User upgrades A number of enhancements have been made to the look and feel of the ?7S II to make it more user friendly, reliable and intuitive. Its magnesium-alloy body is both light and highly robust and the grip and shutter buttons have been re-designed so that the camera feels more natural in the hand. For situations when you just want to blend into the background, silent shooting mode can be activated for 5fps continuous shooting and reliability has been enhanced with reduced-vibration shutter movement. The lens mount has been further reinforced to ensure greater resilience, particularly when attaching third party lenses and users can now charge the camera via a USB power supply whilst the camera is in operation, thus extending battery life. For greater comfort and safety, Sony is also launching the LCS-EBF; a new premium leather body case for the ?7S II which is also compatible with the ?7R II and ?7 II. |

Per i video una bomba atomica .... Per il 12mpx mi sarei aspettato qualcosa di più ... Ma comunque da ex possessore mi sembra un upgrade molto video |
| inviato il 11 Settembre 2015 ore 10:01
Ho sempre affermato che il sensore rimarrà lo stesso nella versione II. resta ancora imbattuto per le sue specificità.
Inoltre, non vendendolo a nessun'altro, con tutta probabilità non hanno ancora ammortizzato i costi di sviluppo.
non è chiaro se abbia af con punti a rilevamento di fase.
mi pare davvero strano che non vi siano?

“ Il sensore è rimasto lo stesso, vedremo l'AF! „
nel comunicato stampa parlano di AF migliorato, però la raffica è rimasta a 2.5 FPS con AF continuo, o 5 FPS senza AF, quindi ho qualche dubbio :-/
Ottima invece l'aggiunta dello stabilizzatore, mentre gli altri aggiornamenti sono quasi esclusivamente per il video. |

Bello tutto, sì, ma lenti nuove non ne annunciano? |
| inviato il 11 Settembre 2015 ore 10:13
L'assenza del modulo a fase la limita parecchio con le ottiche Canon lato foto, andrà probabilmente bene con le native ma la raffica non sarà al livello della a7rII...
Onestamente sono un po' deluso, ottimo upgrade per i video, ma mi aspettavo qualcosa di più dopo aver visto la A7RII.. |

secondo voi un doppio slot per le memorie lo vedremo nei prossimi corpi ??? |
user3834 | inviato il 11 Settembre 2015 ore 10:15
Dovrebbero annunciare 7 nuove lenti... comunque 3400 euro se la possono tenere :D |
