Sony A7S Review Part 2 and Conclusion

A while has passed since part 1 of this review but I’ve been spending a lot of time with the A7S in-between. I am really under the skin of this camera. That’s a good sign because somewhere along the way, the A7S became my main filmmaking tool. Perhaps surprisingly for me, a huge Panasonic GH series advocate on EOSHD over the years, I have been using the Sony A7S more often. The GH4 still has many advantages the A7S doesn’t have, like longer battery run-times, a better screen, quicker boot time and of course an internal 4K codec.

Last chance to order your early 4K raw AXIOM Beta – a Linux based open source camera


The crowd funding campaign for the AXIOM camera ends in just hours and has been a massive success, surpassing the funding target early.

The open source cinema camera is backed by Magic Lantern, Philip Bloom and other leading lights of the DSLR community. It’s the people’s camera, taking control back into our own hands. What’s interesting is that it also unleashes Magic Lantern’s extraordinary ability for the first time outside the closed platform of a Canon DSLR. They now have hardware they can work directly with the manufacturer with, without any need to reverse engineer a DSLR.

This for me is the future of Magic Lantern. To be their own open source camera designer and manufacturer along with AXIOM.

Go to the Indigogo campaign today to get your camera!

Don’t wait much longer, as early units are significantly discounted. After the end of the funding campaign, retail prices will be offered instead.

Key points

  • Top spec option – Super 35mm sensor, 4K raw output, global shutter
  • Alternative options – Micro 4/3 and 16mm sensors for 2K but other benefits like 13 stop dynamic range
  • External recording via 3x HDMI
  • External control via portable device (like smartphone or remote control)

Interview with Panasonic – raw HDMI output may be coming to future GH4 firmware plus anamorphic aspect ratios in firmware V2.0

Panasonic GH4 firmware update version 2.0 and 4K Photo Mode

New firmware for the Panasonic adds higher vertical resolutions in various aspect ratios, making further use of the camera’s 4K video ability.

For photographers also a brand new in-camera workflow is now available to extract high resolution stills from “4K Photo Mode”. For 4K video, resolution increases from 2160 lines in 16:9 for standard 4K to 2336 lines in 3:2, 2496 lines in 4:3 and an enormous 2880 lines in 1:1. By comparison the Red Dragon in 6K records up to 3160 lines vertically (2:1 aspect ratio). An anamorphic lens is needed to take advantage of the resolution gain in squarer aspect ratios such as 4:3 and 1:1. As a huge advocate of anamorphic at EOSHD, I’ll be testing this out very shortly with my collection (below). I’m expecting the results to be stunning.

I caught up with Panasonic recently to discuss the firmware update and more…
