My 85mm GM just crapped out right before a huge wedding shoot in Seattle next weekend and I dont have the budget for another Sony right now.
Ive been shooting for years but never really messed with Sigma glass before. Which Sigma Art prime is actually the sharpest on the A7IV for portraits?

That sounds so stressful right before a big wedding. You might want to consider the Sigma 85mm f1.4 DG DN Art for Sony E-mount. Its very sharp, but be careful to:
- update the lens firmware right away
- check the eye-af reliability in low light I would suggest doing some test shots first just to be safe. Im always worried about new gear failing me!

Yeah, that 85mm is usually the obvious choice, but unfortunately I had issues with the rendering on my last copy. Total bummer honestly. It just wasnt as good as expected when shooting wide open.
- Sigma 105mm f1.4 DG HSM Art Sony E
- Sigma 50mm f1.4 DG DN Art Sony E The 105mm is technically sharper, tho honestly it felt like a heavy workout by the reception.

Like someone mentioned, those Sigma lenses are amazing! I love the output! Im always so worried about gear reliability tho, especially for weddings... so stressful! Since you are on a budget, are you looking at buying new or used? Also, do you need something that focuses super fast for the ceremony, or just for the posed portraits? I always worry about focus missing!
