Well known that the original firmware shipped with the A119s was murky at night. So I've decided to do not film any review on a some beta version and waited for a proper one.
Finally v1.2 was released so here we are.
So - new model "S"! It is a completely different one with the original A119 and the main difference is the sensor.
The A119S is based on Sony EXMOR IMX291. Brief TTX could be found on my local blog IMX291 compared to the prev one - IMX122.
The most important details are below:
Dynamic range: IMX122/IMX322 = 100db; IMX291 = 130db
Snr: IMX122/IMX322 = 54db; IMX291 = 46db
Sensitivity: IMX122/IMX322 = 425mV; IMX291 = 1300mV
As you can see it is not a just new 1080p*60fps mode, but a huge step forward in any param. The most incredible improvement is the sensitivity which is 3 times better!!! Unbelevable
So as per datasheet new IMX291 must be much more better and untouchable for the prev sony sensors and also unreachable for cheep china toys on ov4689 (like the trendvision tv718).
Finally v1.2 was released so here we are.
