I've been shooting with primes lately, but I really need a versatile zoom for my Sony A7III to cover travel and events. I'm torn between the Sigma 24-70mm f/2.8 and the Tamron 28-75mm G2. Since I value sharpness and autofocus speed, which one would you recommend as the best do-it-all lens for a full-frame setup?

For your situation, the Tamron 28-75mm f/2.8 Di III VXD G2 for Sony E is a decent option cuz it's lighter than the Sigma 24-70mm f/2.8 DG DN Art for Sony E, basically saving ur back.

Hey, i feel u, choosing between these two is lowkey a struggle. In my experience, I've tried many zooms and honestly it depends on how much you value that extra width at the wide end. I'm usually pretty cautious with the Sigma 24-70mm f/2.8 DG DN Art for Sony E because it is significantly heavier, which can be a literal pain during long travel days or weddings. Also, iirc some early batches had dust issues, so you gotta double check the weather sealing before committing. Here is basically what I recommend for your A7III:
- Tamron 28-75mm f/2.8 Di III VXD G2 for Sony E
- Lightweight, super fast AF, and reallyyy sharp for the price.
- Sigma 24-70mm f/2.8 DG DN Art for Sony E
- Only if you absolutely need that 24mm field of view for tight indoor events. Personally, I'd go with the Tamron G2... the balance on the A7III is just much better imo. Good luck!!

Been thinking about this... Seconding the recommendation above!! Tbh the Tamron 28-75mm f/2.8 Di III VXD G2 for Sony E is the better value move here. It’s way cheaper than the Sigma 24-70mm f/2.8 DG DN Art for Sony E and basically does the same job.
- Saves you $300+
- Lighter for long travel days Unfortunately, some Sigma units had dust issues... so the Tamron is a safer bet for ur wallet.

In my experience, Sigma is usually better for the wide end, but honestly I've had issues with build quality on those third-party zooms before... not as good as expected long-term. Quick reply: what's your absolute max budget?? Also, do you actually need that extra wide focal length for travel or is the 28mm starting point usually enough for you??
