(sorry for my bad english)
I want to buy the a7iii to increase my skill to shoot in low light thanks to the full-frame.
The question is : Is it possible to shoot in low light (typically concert) with an f/4 zoom lenses with high iso without so much noise ?
Or, should I buy only prime lenses at f/1.4 or 1.8. The problem is the 2.8 Sony zoom are too expensive for me.
Which average ISO value do I need to shoot in low light at f/4 and 1/150 sec ?
Thanks a lot for your very precious advices !!
