I've included their A7S DR chart above, looks like it may have more under than over if you check it out on a Waveform.Would definitely be interested seeing more tests done showing the camera compared to the AMIRA or ALEXA in different shooting scenarios, pushing middle grey on all of them over and under.While the full-frame 1080p/4K a7S from Sony is proving to be an absolute beast in low-light situations, it's far more than just a night-shooting camera.Besides resolving what looks like a very solid 1080p image (an external recorder is required for 4K), it's also got some pretty fantastic dynamic range. Well the folks over at cinema5D took the camera for a spin, and measured it at over 14 stops, right next to the ARRI AMIRA, which uses the same sensor as the even higher-end ALEXA, which is being used on tons of Hollywood and indie features.It's not perfect but the amount of extra highlight information in a BMPCC raw frame that is processed to linear exr is admirable for a 0 camera.
There are maybe one or two other sensors that can make that claim.
However, film kicked video's arse a long time ago when it comes to narrative storytelling for a number of reasons, not the least of which is film's beautiful highlight performance. And if you want to see a whole bunch of cameras profiled against each other, I have the profiles you can download and load into teh Sekonic DTS software here: that helps.
:) BTW- If someone does have access and the time- here is how the over / under evaluation can be made using the published charts: (I can't get to this until at least the end of the week.) 1.
But it also looks like (based off of the chart) that if you rate it that way, you only get about 5-ish stops of under exposure range. But for people who want to see into the shadows more, might be an issue... I'm not a fan of slog3 because it puts more detail in the shadows at the cost of highlights where as slog2 which I love on the F5 has really great highlight detail and rolloff.
To me the eye is drawn to highlights not shadow, so it makes sense to use slog2 over slog3. There have been countless tests run on the BMCC and it's dynamic range.
