I know the answer for stills but as somebody who is not a video shooter and new to contrast only af, will a fast prime noticeably improve the AF on the S5 over and above the kits lens in an indoor environment. I am assuming yes but want to make sure before purchasing.

Also, assuming Panasonic is the better option for video AF over Sigma.

I am aware of limitations of the AF system for video but looking to maximise performance where possible.

If anything. Shallow depth of field with fast primes makes the S5 hunt even more in video AF. I had the Lumix 85mm and it was way worse than the kit 20-60.

Thanks for sharing your experience.

I knew that lenses with big apertures (like f/1.4) will generally be slower to focus on pretty much ALL cameras (dslr or mirrorless).
