High Quality Web Cam for Teleconferencing while Remote Working

Most laptops have rather poor web cams built in.
Apple laptops have historically used distinctly average sensors in their "iSight" or "FaceTime" cameras...
In _some_ situations having a 720p camera with a "average" lens quality is not "_fit for purpose_" e.g. when doing a face-to-face call with a client where we want as much quality as possible.

Logitech makes the best web cams I have used.
I've been using a C920 for the past few years and the quality is _really_ good. 😍

These cameras have a fixed lens but _good_ autofocus capability and built-in stereo microphone.
Overall I think they are an _essential_ tool for remote working.
(_provided the person working remotely has a good/stable internet connection which can support streaming video..._)

A similar model is the B910: https://www.amazon.co.uk/Logitech-B910-USB-HD-Webcam/dp/B0047IKGIM/

The British Heart Foundation is currently selling a Red (Google Plus branded) B910 "Business Model" with a **1080p** sensor and Carl Zeiss optics on their eBay store for £35

I _really_ like the fact that it's Red and has a privacy filter.
I've _ordered_ one to try it.
if anyone the @dwyl team would like one of these please leave a comment. 👍
