New Nikon 10-24mm wide angle

I looked at the 10.5mm fisheye today at a major pro camera place and he showed me what he said was a just out Nikon 10-24mm wide angle that does not have the signifucant barrel distortion of the 10.5mm fisheye.

Of course I asked him if the coverage on a DX format was as wide, int he 180 degree range as the 10.5 fisheye, and he did not know...time for me to look it up!

The Nikon 10-24mm Wide angle lens will require around 17 images to cover the full 360x180 panorama sphere on a DX sensor at the 10mm setting.

As apposed to 6+TB (8 images) for the 10.5mm Fisheye.

Barrel distortion is not an issue if you correct for it with software.

So much for that lens! lol.

TB is an abbreviation for? I know the nadir shot is needed, but I hear the zenith is not if I recall

TB = Top/Zenith Bottom/Nadir

Using the 10.5mm you can shoot in different methods. What we would have classed as normal would have been 6 shots at 0 degrees with 60 degree click stops + 1 shot at +90 degrees (T) and 1 shot at -90 degrees (B).

A better method is to shoot 6 shots at -15 degrees with 60 degree click stop + 1 or 2 shots at +65 degrees (T) 180 degrees apposed and then a hand held (B) Nadir with the tripod removed from the scene. Or simply cap, clone or heal the smaller tripod from the scene.

The reason for the +65 degrees (T) Zenith shot/s is to allow for more items to be in scene to assign control point too. Where +90 can leave you with just a featureless blue sky or white ceiling etc.

I hope this make sense and clears things up for you.

If I understand your explanation correctly, when pointed upwards 65 degrees off horizontal axis, then with your suggested method, 1 or 2 shots are taken tilted up 65 degrees for the top of zenith.

The two slightly different methods floating around here for the Nikkor 10.5 were the source of my confusion, although at this stage of newbie-ness, that isn't difficult to do, lol.

Yes, but the two +65 degree shots are 180 degrees apposed. It can be a case only one of these shots will be required but if you have both you are very likely to have areas that control point placement will be easier.
