've been testing out the 3.0 Software Update Packet, and it is looking pretty smart. Aside from the 'big-deals' of playback on-board, 3200EI and audio recording, gamma settings now have their own tab on the home menu, allowing almost every output to have it's gamma set.

The 'Grab' function appears to be working well, if a little slow. 10 seconds to dump JPEG (approx 500kb file size), 45 seconds for TIFF (approx 11mb) and about 30 seconds for DPX (approx 7mb). This could be good in stereo-work for on-set HIT applications, and maybe 'grabbing' the slate.

Playback is excellent - particularly responsive, and no noticeable delays on button presses. Lovely to watch 60fps footage at 25 on camera.

The camera (according to release notes) has the ability to record the image stream to two SxS cards simultaneously, although I haven't been able to get this to function. Potential uses perhaps being one card straight to editorial and one card to the Data Wrangler/DIT perhaps.

The EVF also has some nice updates - RGB 'bleed' and strobing when panning is significantly reduced, and there is also a 'Smooth' option which gives the EVF display what can only be described as an 'interlaced' feel. EVF white point is also locked at 6500k which should save some complaints from operators worrying about what they're seeing not matching up 'by eye', with what's kicked out.

Sync'd playback when two Alexa's are operating in 'master and slave mode' over ethernet, for stereo applications would be most welcome.

The Beta was updated again today (still Beta, release hopefully next week). I believe the simultaneous record to 2x SxS is operational. REC709 & LOG are greatly improved.

How can you "improve" log?

Surely it's either the logarithm of the sensor data to some power... or it isn't?

Ah, no, wait, this'll be the "special log" that manufacturers like to modify every so often. For our next trick: improved values of pi!

It is the balance of the color matrix and it is also aligning brightness values more accurately to the noise floor.
