Before I give advice, quick question—are you shooting these walkthroughs purely handheld or using a gimbal?? It makes a huge difference with that extra crop from Active Stab, you know? Anyway, jumping in here cuz I’ve been using the APS-C Sony bodies for ages and I'm super satisfied with the third-party stuff lately. 1. Tamron 11-20mm f/2.8 Di III-A RXD - Look for this used! I’ve seen it go for around $480. Having that zoom range is honestly a lifesaver for tight bathrooms vs larger living areas.
2. Samyang AF 12mm f/2.0 E - This one is a total steal at around $330. AF is actually quite reliable for travel vlogs, right?
3. Sigma 10-18mm f/2.8 DC DN Contemporary - If you can find a used deal for $490, grab it. It’s basically the gold standard for tiny setups and handles focus breathing like a champ. So yeah... let me know about the gimbal situation and I can give you a better technical breakdown!! peace.

Sooo I went through this exact same transition last year. Coming from full-frame, that Super 35 crop is a total reality check. Basically, when you factor in the 1.5x sensor crop plus the ~1.1x from Active Stabilization, your field of view gets eaten alive. For real estate, I realized I needed to hit at least 10mm or 11mm on the lens just to make small rooms look decent. I spent weeks testing different setups on my FX30 to see what would actually hold focus during a fast walkthrough. Here’s how the two I experimented with compared: • Sigma 10-18mm f/2.8 DC DN Contemporary for Sony E: This ended up being my personal 'goldilocks' lens. It’s incredibly light, which was massive for my gimbal work. I found the AF to be basically silent and very sticky. Plus, that extra 1mm on the wide end (compared to the Sony E 11mm F1.8 already mentioned) actually made a visible difference in tight bathrooms for me. • Tamron 11-20mm f/2.8 Di III-A RXD for Sony E: I tried this one cuz I wanted weather sealing for travel stuff. It felt more rugged, but it’s definitely bulkier. While the AF was great, the Sigma felt just a bit snappier for my style. I also briefly used the Samyang AF 12mm f/2.0 E when I was really tight on cash. It’s super sharp, but for real estate, I found 12mm a bit tight once I turned on that stabilization crop... I was basically hitting walls trying to get the shot lol. I eventually settled on the Sigma because it just felt the most balanced for the price. 👍

> I’m primarily shooting indoor real estate walkthroughs and some travel vlogs... My budget is capped at around $500, and my main concerns are autofocus reliability—since the FX30's AF is so good, I don't want a lens that hunts. Honestly, for your situation, I would suggest sticking with first-party glass to avoid any potential headaches. I've been using the FX30 for a while now and while the Viltrox is tempting for that f/1.4 speed, I'm always cautious about third-party AF reliability for professional paid work. In my experience, the Sony E 11mm f/1.8 is the absolute "goldilocks" lens ur looking for. Basically, the native linear motors in that lens are dead silent and they just *work* perfectly with the camera's tracking. If ur doing real estate, the last thing u want is the focus hunting while ur mid-walkthrough. Plus, it handles focus breathing way better than the 13mm. Seriously, focus breathing can lowkey ruin a professional look if you aren't careful with ur transitions. One thing to make sure of is the weight—the 11mm is tiny. Since u mentioned handheld movement, keeping the setup light is gonna save ur wrists during long shoots. But just a warning: be careful when using Active Stabilization!! It adds a significant crop on top of the Super 35 sensor, but because this lens is so wide (roughly 16.5mm equivalent), you'll still have enough room to capture those tight rooms. I'd definitely play it safe and go with the Sony lens for the peace of mind. gl!
