Schon etwas älter, aber meines Wissens hier im Forum noch nicht behandelt:
Für die Sony Alpha ILCE-7S gibt es ein Firmware-Update, das einige Verbesserungen gegenüber den ursprünglich bekanntgegebenen Spezifikationen bringt:
Unterstützung für einen Lautlos-ModusEmpfindlichkeitsbereich im Videomodus vergrößert auf ISO 100 - ISO 102400 (erweiterbar bis ISO 409600)Dynamikbereich für RAWs auf 15.3 EV erweitert.
Da diese Verbesserungen implementiert wurden, bevor die Kamera überhaupt ausgeliefert wurde, dürften sie bereits in der einzigen bisher bekannt gewordenen Serienfirmware "ILCE-7S v1.00" implementiert sein (wohingegen die "ILCE-7S v0.01" sie höchstwahrscheinlich noch nicht aufwies):

ZITATα7S now offers a ‘Silent Shooting’ mode
By David Kilpatrick, on May 30th, 2014
Today, Sony confirmed a rumour – no doubt started as a result of pre-production tester leaks – that the A7S would have a completely silent all-electronic shutter mode. This is not the same as the Electronic First Curtain shutter found on the A7, A99, A77, A6000 and so on but conspicuously absent on the A7R. Nor is it the same as the near-silent leaf shutter terminated exposure mode of the RX100 models, RX10, or RX1 models. It’s completely free of all mechanical action and totally silent.
The silent shutter has been implemented as a firmware upgrade to the early production samples and future stocks, along with several other important firmware enhancements – all of which will have Sony owners wondering why improvements to their six-month old or one-year old purchases are not equally forthcoming. These are however improvements to a £2,100 camera body which will not hit the shops until the end of July 2014.
The firmware fixes and upgrades are:
- α7S now offers a ‘Silent Shooting’ mode
- ISO range for Movie Shooting extended to ISO100 – 102400, expandable to ISO100 – 409600
- Dynamic Range extended to 15.3 stops as sensor RAW output
The silent mode is an option, and we would guess it carries some penalty in terms of available shutter speeds or noise performance. They say "For situations where absolute silence is required on a shoot, such as nature shoots or behind the scenes at a movie production, the α7S will offer the user the ability to activate ‘Silent Shooting’, thus making the photographer as unobtrusive as possible.”
A further upgrade is the expansion of the ISO range when shooting movies (previously limited to the native range). The α7S now offers the ability to shoot between ISO 100 -102,400 (native range) and is expandable to ISO 100-409,600 whilst still shooting capability remains at a staggering ISO 100-102,400 (again, the native range) expandable to ISO 50-409,600. The sensor’s dynamic range has also been further extended to 15.3 stops sensor RAW output. Technical note: as the bit depth remains unchanged and is presumed to be 14-bit ARW, this enhancement implies a modified raw gamma curve.[/quote]
Diesen 'Silent Mode' gibt es allerdings nur in der ILCE-7S, die ILCE-7 unterstützt immerhin noch ECFS, die ILCE-7R auch dies nicht.
