He doesnt have anything faster than f/2.8!
I do agree with the 77 f/1.8 for the reception candids (i used it a ton) but it is not in his list...
And though it'd be great to have it available, IIRC i took many f/1.8 but at ISO800 or 400... so yeah, had i not had the f/1.8, somehow i could still manage the shots. Not ideally, but still doable.
