Hi there,
currently I only own a Dahua HDBW2431R-ZS-S2. Bein a varifocal I ordered it to get a feeling of what fixed lenses I need for my coming installations.
Now I know and I see it's getting hard getting cameras with one of the standard focal length for my desired field of view. So I'm thinking about getting all varifocals.
But what I noticed is that at least my 2431R distortes the image quite a bit in the wider settings. That's nothing to wonder about, but what I want to know is, if a fixed focal lens at e.g. 2,8mm or 3,6mm does distort the same amount or if it's the zoom lens were that effect if pronounced.
Thanks,
Reah
