I am considering purchasing a lens for real estate and architectural photography. I am wondering if someone might be able to make a recommendation? I am considering a Tokina 11-16mm 2.8. I was looking at a Sigma 14mm, but find it could be a disadvantage using a fixed focus lens; it is more expensive. I could really use some assistance. The cameras I presently have are the Nikon D600 and the D7000.
The ideal effective focal length for shooting real estate interiors is between 16 and 24mm and since the D600 is a full frame body and the D7000 is an APS-C sized sensor and has a 1.5 focal length multiplier on the effective focal length, it is impossible to get a lens that is ideal for real estate photography on both camera bodies.
I would not recommend the Sigma 14mm. It is too wide (14mm effective) on the D600 and just barely wide enough (21mm effective) on the D7000. The Tokina 11-16mm is ideal on the D7000 but not designed for a full frame body like the D600. Reports are that it will work on full frame bodies at 15 and 16mm but that it has soft corners. A much better choice for a real estate photography lens for the D600 would be the Nikon 14-24mm.
