Which Sigma Art primes offer the best performance on L-mount cameras?

Question

I've got a huge gallery opening in Portland in three weeks and my current gear just isnt cutting it for the low light shots I need to finish. Im stuck between the Sigma 35mm f1.4 DG DN and the 85mm f1.4 Art lenses for my Panasonic S5IIx. My budget is capped at $1100 and I really need something that wont hunt for focus when things get busy. I'm leaning toward the 35mm for versatility but that 85mm look is so tempting for the portraits I still have left to shoot. Im just worried about the weight and the AF speed on this specific mount... Which Sigma Art primes offer the best performance on L-mount cameras?

Be careful with that 85mm in tight spots. For your $1100 budget, you might want to consider the Sigma 35mm f1.4 DG DN Art L-Mount. I would suggest going with it because its way more versatile for low light. Make sure to look for open box deals to save extra cash. The 85mm is gorgeous but might hunt more than youd like when things get busy.

Regarding what #1 said about "Be careful with that 85mm in tight spots...." - theyre totally right, but my issue is more about the actual focus tech. Unfortunately, some of the Sigma Art glass just doesnt play as nice with the S5IIx phase detect as youd expect. I had issues with the Sigma 35mm f1.4 DG DN Art L-Mount hunting in dim settings, which was disappointing because it should be a workhorse. Its just not as snappy as I need when things are moving fast. If youre worried about performance, here is the reality:

Sigma 50mm f1.4 DG DN Art L-Mount

This is the one you actually want. It uses the HLA motor. Its way faster and more quiet than the 35mm or 85mm.

Sigma 85mm f1.4 DG DN Art L-Mount

The images are stunning but it feels like a workout. AF is okay, but definitely not class-leading for video or fast stills.

Sigma 35mm f1.2 DG DN Art L-Mount

Way over your weight limit. Its a monster thatll kill your wrist. Tbh, if you want that gallery to look perfect without the AF failing you, the 50mm is the sweet spot. It fits your budget and the tech is just better. The 35mm f1.4 is a bit dated now compared to their newer HLA lenses, and I wouldnt trust it for a one-time gallery shoot where you cant afford to miss.

Building on the earlier suggestion, it seems like the 35mm is winning the versatility battle but you really gotta watch those prices. If your budget is a hard $1100, I would suggest looking at used options on sites like MPB. You can usually snag the Sigma 35mm f/1.4 DG DN Art L-Mount for way under your cap, which leaves room for other gear you might actually need. I've used both and honestly, the 85mm is a total beast for portraits, but the AF on the Sigma 85mm f/1.4 DG DN Art L-Mount can feel a bit more deliberate... maybe too slow if things are moving fast. Be careful about the weight too, since carrying that heavy glass all night at a gallery is gonna be rough on your wrist. Basically, if you want to play it safe and save some cash, the 35mm is the move. Just make sure to update the firmware to help with that hunting issue mentioned earlier... it really makes a difference on the S5IIx.
