In Topic: Sony Alpha 7S for video - ???

20 August 2014 - 05:04 PM

When shooting with the A7S, for the S-log2 profile (similar to GH4's Cine-D I think), the minimal ISO that's allow is 3200. Go figure.

 

According to Sony, S-Log2 ISO3200 is the optimal setting to deliver the widest (14+ stops) dynamic range. FWIW, EOSHD comparison stated that A7S ISO3200 looks like 5D3 ISO200 (near the middle of the review).

A7S Clarification:
Movie settings, including Set Custom White Balance, should be done in P, A, S, or M mode.
Turn the Mode Dial to Movie to choose whether to use P, A, S, or M settings for video.
With the Mode Dial left at the Movie position, Set CWB is grayed out, however, 3 CWB done in P, A, S, or M will still be selectable.

From my observation, the Sony A7S with its amazing low-light capabilities, FF IQ and DOF is becoming the preferred mirrorless 4K camera amongst professional filmmakers and the saving on lighting (purchasing, renting, transporting) can easily offset the cost of the external recorder. For now GH4 with internal 4K recording will be the preferred 4K camera amongst divers until Sony delivers internal 4K recording for A7S Mark 2 (??).

Since switching system is expensive, looking long term, the Sony mirrorless system has the most potential and more future proof, IMO.

I heard on one review that manual white balance was not possible while doing video with the A7S - if that's true I think it would be a deal breaker..

 

My hand-on experience: In the Movie mode, A7S can perform all of the White Balance functions except Set CWB. The easy workaround is to set up to three CWB settings in P, S, A, or M and all three CWB settings will be accessible in the Movie mode. Hopefully, this little inconvenience will be corrected in the next firmware update. BTW, A7S also has an Auto Underwater WB function, but I don't know how well it works.

cinema5d.com tests show that the mirrorless fullframe A7S with 14.1 stops dynamic range has way surpassed the fullframe dSLR 5D3 with 11.8 stops.

 

Increasingly there are welcome news that the most compact and affordable fullframe mirrorless coming this year.
