Ive been shooting on the FX3 for about a year now mostly using primes like the 35mm and 85mm G Master glass which looks amazing but honestly im getting tired of swapping lenses every five minutes during run and gun shoots. I just landed a gig filming a mini-doc for a local chef in Chicago and I am gonna be in a super cramped kitchen with basically zero time to swap gear without getting grease on the sensor or just missing the action entirely.

Ive been looking at the 24-70 GM II but its pricey and i heard the focus breathing can be a bit much though maybe the FX3 internal compensation fixes that? Or maybe the 24-105 f4 for the extra reach but i worry about the f4 being way too slow in the dim back-of-house lighting. I have about $2300 to spend and I need to pull the trigger by next week before we start production. Is there something better than the standard Sony glass like that Tamron 35-150? That range sounds perfect but its a total brick and I am worried about how it balances on a gimbal if i have to switch over to the RS3 mid-day.

Anyone here use a one lens to rule them all setup on the FX3 that actually holds up for professional delivery? I really need the AF to be rock solid because I am solo op on this one and cant afford to hunt for focus...
