Wedding Filmmakers: Sony 20-70 F4 vs the Sony 24-70 F2.8 II

[monosifon]

What are your thoughts on using the new 20-70 F4 vs the 24-70 F 2.8 II for wedding filmmaking specifically the tradeoff of getting more reach on the wider end versus the change in aperture. The weight differential seems negligible to switch as well. What are your thoughts?

I'm not a wedding photographer, but I would go with the 2.8, I think it would be useful in low light wedding venues. The 20-70 looks awesome though
