I’ve actually not used the HDR setting on the 5Diii yet! You’ll have to let me know how it goes with your experiments @kina. 🙂 I imagine fish eye lenses would look odd for the purpose he’s using them for. I have the 16-35 so that’s what I’d use (at 16mm), so just use the widest you have without it looking too warped. The attached photos are at 17mm, and they feel natural enough to me. And make sure to point straight on, the camera perfectly level, not pointed up or down. I use f/16, manual focus, and in the past have done manual HDR merging in PS. Lighting I usually do all natural, though my brother who does real estate photography professionally has a special method for photographing and merging bounce flash photos. I don’t do real estate enough to have his method memorized. 🙂
