Provoking Red Dot Flare

Based on a recent discussion here (ref. 1, see below) I did a quick test with my Fuji and Nikon cameras and including my son’s Canon, just shooting against the sun with a dark foreground to let the red dots shine.

From the left to the right:
- Fujifilm X-T4 + 10-24/4.0
- Nikon Z7 II + 14-24/2.8
- Nikon D7200 + 16-80/2.8-4.0
- Canon EOS RP + RF 24-105mm/4.0
all shots at 24 mm equ. F/8.0

The way I see it: Fuji comes out worst, showing a pronounced pattern of red and green dots.
The Z7 II may look much better, there is less flare overall, but – big but – the flare includes some quite pronounced red dots – unlike with the Nikon DSLR or the Canon.

It is certainly not a scientific test, e.g. due to the different lenses,
however, the results basically confirm the that the short flange distance of mirrorless cameras promotes the effect to have distinct red dots (ref. 2, see below). That said, Canon seems to have found a way to address and to reduce the issue. Unfortunately, I have no Sony (yet) to check.

Open for comments.

Best regards, Peter
