Yes, this is a DX lens and I shouldn’t expect its image circle to cover the D700 sensor… but let’s try anyway. Here are images of my ceiling at f/2.8 at 11mm through 16mm with no lens corrections applied:

11mm

12mm

14mm

16mm

If we add lens correction to the 16mm image, it doesn’t look that terrible!

16mm with lens correction

Here are a few examples at 16mm. They aren’t perfect but I would consider the lens useable in a pinch… at least until I figure out what to use for my wider-than-35mm lens.
