I recently purchased a Sony a6400 and I'm looking to get a high-quality wide-angle lens to capture expansive landscapes and architecture photos. I'd ideally like something that's sharp edge-to-edge, has fast and quiet autofocus, and won't break the bank.

I've been looking at options like the Sony 10-18mm f/4, Sigma 16mm f/1.4 DC DN, and Samyang 12mm f/2. Based on my research, they all seem like great lenses but I'm open to other suggestions as well.

If anyone has experience using wide-angle lenses with the a6400, I'd love to hear your thoughts on what the best option would be for under $1000. What lens have you found works best for landscapes and architecture shots? Appreciate any advice!
