I recently set about testing my new(ish) Sony 16-70 mm lens out for street photography, and I decided to film it for another episode of Street Photo Diary. I was also trying out a new GoPro to film the POV shots. I had previously used an old GoPro Hero Session to do these, but the quality wasn’t great and the battery, which can’t be replaced, would only last about a half an hour (after a few years of use).
