OK I have loaded the images I took at the Manchester NPS Roadshow.
This is the scene with my D3, and the NPS 8-15mm fisheye zoom at 8mm, all images taken at f6.3.
This is taken close up of the D850 at 15mm
This was at 12mm.
And 8mm.
These pictures are of the cup which was in the second set of windows from this end in the first image, near the man slightly crouching.
At 15mm, all taken straight into the sun.
At 8mm, notice my jacket intruding, Sun peeking through the handle.
At 8mm again.
All images basic processed in Lightroom using the new auto adjust, with a very quick individual fine tune.
I can post unprocessed versions but directly into the sun, out of the camera not ideal. I took no trouble to check the exposure, just took the shots without bothering too much about niceties like that.
