Full Spectrum Z5 with MC 105mm/2.8 S with 720nm Infrared Filter

I went for a walk around high park with my full spectrum converted Nikon Z5 and my MC 105mm/2.8 S macro lens and a 720nm Infrared filter. Wide open, this is a wonderful combination. But stop it down to anything smaller than /5.6 and a bright spot appears right in the centre of the image. This bright spot has lower contrast and a different colour from the rest of the image. The colour can be hidden by converting the image to black and white, but this does not solve the reduced contrast. Best to shoot wide open if you're using this one for an infrared shoot. _________________________________________ http://kyleclements.com
