Shooting my first Sunday League game – any tips?

This Saturday I’m going to shoot my first football match at Sunday League level, mainly to gain some experience and hopefully get some good shots for my portfolio.

I’ve already read a few previous posts on here, and they were really helpful, but I still wanted to ask for some advice based on my specific setup and situation.

At the moment I’m shooting with a Sony A7III and I have two lenses: a Sigma Art 24-70mm f/2.8 and a Sony 70-200mm f/2.8 GM (mk1).

Right now I’m leaning towards bringing only the 70-200 and hoping it will be enough to cover at least one side of the pitch, especially the attacking half.

My main goal is to avoid as many beginner mistakes as possible, so I wanted to ask for some advice from people with more experience shooting football.

A few specific questions:

• Is a 70-200 f/2.8 enough for a first Sunday League match, or am I going to feel too limited?
• Would it make sense to bring a small stool and shoot from a lower angle?
• Do I need a monopod, or is it better to stay handheld at the beginning so I can move more freely?
• I think the main use for these photos will be Instagram, but at the same time I’d also like to use them in my portfolio. Is it better to shoot vertically or horizontally?
• Since I don’t have any deadline to deliver the photos, is it better to shoot RAW only, or would JPEG also make sense?

Any general beginner tips would also be really appreciated, especially things you wish you knew before shooting your first football match.
