For problems with aperture ratio (it’s hard to shoot indoors), I bought a flash. Once after filming in extremely low temperatures (driving on a snowboard and shooting), the burst mode stopped working. Reconnecting helped. Some write "vacuum cleaner" - I personally pah-pah-pah did not notice this. In general, I thought this was a problem only for televisions. Although, I always have a camera in my bag - maybe it has been saving me for 2-3 years already. P. S. It seems to me that now it is better to take a Canon EF 28-135 f / 3.5-5.6 or at 200
