> honestly so done with this bulky 24-105 zoom, the f4 is just killing me for low light stuff. I hear you on that f4 struggle. It works well enough in daylight, but once you lose the sun it is just a headache. Since you have a $800 budget, you actually have some really reliable options that wont let you down for the Chicago gig. Personally, I've been very happy with the Sony FE 35mm f/1.8 Lens for a while now. It is incredibly sharp for the price and so much lighter than that zoom you are carrying. No complaints about the build quality either; it feels safe and solid on my a7IV. You can usually find it for around $600 to $700 new, which leaves you some extra cash for other gear or travel expenses. If you need more reach, the Sony FE 85mm f/1.8 Lens is another safe bet. It is basically the gold standard for budget-friendly primes in the Sony ecosystem. It stays well under your $800 limit and the image quality is consistently sharp. I tend to stick to native glass because the compatibility is just guaranteed, which is important when youre doing paid work. Both of these are straightforward, no-nonsense tools that get the job done without any fuss. Sharpness is definitely there on both... just depends on what focal length you prefer for the shoot.
