You want the lowest f-stop number possible for telephoto, so you have more available light hitting the sensor. This allows you to get a higher shutter speed. The higher shutter speeds compensate for the exaggerated shake you get from the longer lens.
- ahnick 6y agoIf this is the case, then can we infer that the iphone 12 pro has a slightly better telephoto lens than the iphone 12 pro max? (The max's f-stop is listed as f/2.2)
- mullingitover 6y agoThe lens is better, yes, however the sensor on the pro max is significantly larger, so I think it's basically a wash.
