I just dropped a ridiculous amount of money on this R6 Mark II and now I am literally staring at an empty lens mount because I cannot for the life of me decide what to put on it. I have this huge family reunion coming up in Austin next month and I promised everyone I would take professional-looking portraits but I am totally overthinking the glass situation. I've been shooting on an old Rebel for years so this is a massive jump for me and I don't want to mess it up by picking the wrong lens for this specific body.

So I was thinking about just biting the bullet and getting the RF 85mm f1.2 L because every single YouTuber says it is the holy grail of lenses but then I see the price tag is like $2700 and I just cant do it. My budget is strictly $1500 max because I still need to buy extra batteries and a decent bag for the flight. Then I looked at the RF 85mm f2 macro which is way cheaper but then I read these forum posts saying the autofocus is kinda clunky and slow compared to the L series and I am worried it wont keep up with my nieces and nephews running around the park. Is the motor in that thing really that loud and annoying for photography?

My logic was maybe I should just get a used EF 85mm f1.4 IS and the adapter but then I heard some people complaining that using the adapter can sometimes make the eye-tracking feel jittery or inconsistent on the newer bodies and that just frustrates me because the eye-autofocus is the whole reason I upgraded to the Mark II in the first place. I don't want to spend $1500 on a used lens and an adapter just for it to behave weirdly. Then there is the 50mm f1.2 which is also crazy expensive or the 50mm f1.8 which feels like putting budget tires on a Ferrari.

Is the 85mm f2 actually good enough for moving targets or am I gonna regret not getting something faster? Or should I look at a zoom like the 70-200 f4 even though I lose that really shallow depth of field? I am just going in circles here and the trip is getting closer and I still have nothing to shoot with...
