I've had my SONY A7SII or A7S2 for about 3 weeks now and being new to Sony cameras, it was imperative that I learnt about each function and where to easily find each setting. When out on the streets of London shooting StreetStyle images you need to know exactly how to setup and change your camera settings based on the lighting, weather and subject promptly. Not only that but so often when shooting outside the lighting changes and therefore you have to make small adjustments to your camera settings to combat this. If you take 5 minutes to change settings, especially in London you would have missed the moment and the chances are the lighting would have changed again. So before using any camera, I recommend learning about each setting and what effect it has on your stills and video filming.
