F/1.8 is a familiar number to people only because of how that number matters for a full frame, APS-C, or 4/3 sensor. It doesn't translate well to what would produce good image quality on an 8mm sensor. The equivalent F number will be much higher. Using it in this context is just marketing. I'm not saying it's bad, just that the information they're giving isn't what people will understand it as, which I think is a bit misleading. My friend wrote a very interesting article on the topic if you're curious - I had no idea about most of this: https://www.dpreview.com/articles/2666934640/what-is-equival... |
