Wait, are you doing video walkthroughs or just stills? if its just photos, the 7Artisans 15mm f/4.0 Full Frame ASPH L-mount works surprisingly well. Im satisfied with how it handles field curvature. For real estate, you want those lines straight and this lens delivers if you stop down to f/8. its fully manual but honestly, the hyperfocal distance is so forgiving at 15mm that you wont miss autofocus at all.

Saw this earlier and wanted to chime in. I have been very satisfied with the Samyang AF 14mm f/2.8 Full Frame L-mount for architectural work. Since real estate involves static subjects, you dont really need fancy tracking. Methodically stopping down to f/8 yields impressive sharpness across the frame. Vital for professional listings. Its a cost-effective solution that performs reliably in cramped spaces... definitely worth a look for your S1.

I would suggest checking out the Venus Laowa 14mm f/4 FF RL Zero-D L-mount because that zero distortion spec is huge for real estate work. Just be careful since its fully manual on your S1. You might also look into:

• Panasonic Lumix S 20-60mm f/3.5-5.6 L-mount
• Sigma 20mm f/2 DG DN Contemporary L-mount used Make sure to watch for corner vignetting at f/4, tho. Let me know if you need more specs!

Honestly, everyone here is overthinking the manual focus situation for real estate. Like someone mentioned, you dont need fancy tracking, but jumping into these specific manual lenses is just adding headache you dont need right before a gig! If you want to keep your sanity and stay under budget, you should really just hop on YouTube and search for Lumix S1 ultra-wide budget shootouts. There are some fantastic channels that do side-by-side comparison charts with real world sensor data that will blow your mind. I saw a super detailed breakdown a few weeks ago that compared the distortion profiles of a few different options and it was basically the holy grail of info. Just type budget L-mount wide angle review into the search bar and you will find exactly what you need in like ten seconds. Why stress over random forum advice when there is actual objective sharpness data out there waiting for you?

Late to the party here but I wanted to share my disaster story so you dont make the same mistakes I did. I tried to cheap out on a real estate gig last winter with my S1 using a random old wide-angle and a bargain-bin adapter. I thought it looked fine on the back screen, but once I got home... man, it was bad. The adapter had a tiny bit of wobble I didnt notice, and it threw the whole focal plane off. Half the kitchen was sharp and the other half looked like it was underwater. Watch out for these things if you go the budget route:

• Loose lens mounts or adapters that have even a millimeter of play
• Heavy decentering where one corner is way softer than the others
• Lenses that dont talk to the S1 properly, which can mess with the internal stabilization It was honestly such a letdown because I had to spend all night in post-processing trying to mask the blur. Its just not worth the stress when you have a client waiting. Really made me realize that some budget options just arent reliable enough for professional work where you only get one shot at it.

Did this last week, worked perfectly
