Sony A7R II Video Capabilities - 4K

A7R II Review – 10 – Video

The A7R II should please video enthusiasts and professionals in many ways. 4K, S-Log 2, the bumped up ISO performanceSteadyShot and many more things make this camera a very viable option for videographers.

SUPER 35 EQUIVALENCE TO FF 35MM
According to my rough calculations the focal length equivalence of a lens you put on your A7R II in Super 35 format has to be calculated x1.4. So to make my life easier you can just remember to multiply it by 1.5 to roughly calculate the field of view.

That means that…
A 16mm gets a 22.4mm equivalent field of view.
A 35mm gets a 49mm equivalent field of view.
A 55mm gets a 77mm equivalent field of view.
A 70mm gets a 98mm equivalent field of view.
A 135mm gets a 189mm equivalent field of view.
A 200mm gets a 280mm equivalent field of view.
A 400mm  gets a 560mm equivalent field of view.
A 600mm gets a 840mm equivalent field of view.

The super 35 FOV behaves almost like APS-C.
Remember that there’s the full frame 16:9 readout for even wider shots for instance.

FULL FRAME READ OUT VS SUPER 35
I have tested the crop size differences between 3 modes in this video.
Full frame still picture, full frame video readout, super 35 format and scaled the Super 35 footage to 150% afterwards.
