That took some finding!  2003!

D1X and 50mm lens.

The hotspot is a magenta spot arrowed.

On white boots it didnt show...on coloured boots the discolouration disappeared but on black boots! 

I bought 3 different 50mm f1.8 lenses ( kept returning them to Jessops - no wonder they went bust!)

Bought 2 50mm f1.4 lenses from another source - still the same!

Tried all combinations of lighting to see if it was an errant reflection...even with a time exposure with modelling lights it showed this hotspot.


In the end I shot the images with the 17-35 at 35mm .....and a little closer.

The 17-35 is now my standard IR lens ...as it has no hotspot at all!


Edit - This was an untouched nef file resampled for viewing but it doesnt show up as much when posting on the forum???? So to make the hotpot more clear on all screens I have just run a saturation brush over the area to make it a tad more obvious.
