I've got a few dash cams over the last week now while trying to find out the best match for my needs, and I just wondered how come no manufacturer seems to be matching a good low light lens with the Ambarella A7 chips?
All of the A7 devices I've seen are using a lens with an aperture of 2.0. I've seen some newer devices mentioned on here which are the A7L with a different lens but that is an aperture of 2.5.
The GT680W I have is the Novatech / Aptina combo but that has an F1.6 lens?
I just wondered if there was another reason for this other than just cost as a lower aperture lens would help the A7 devices out with their low light performance?
Thanks in advance
