Following up on our IG Reels HERE, here's an addendum to that segment with screencaps to show higher clarity. Still images have a limitation of omitting noise flux but it does show more static image characteristics such as contrast, sharpness, etc.
All images can be clicked to show the 4K high-res screen caps.
Lastly, here are some screen caps showing off-axis flare suppression. Pay attention to the light source inside the garage at 8 o'clock.
Observations (in no particular order):
• Old Carsons maintain sharpness over a larger centre zone (pay attention to the markings on the satellite dish on top of the garage), but off-axis flare suppression is not as good as Edmund or Carson when panning
• Edmund lenses improve on flare suppression over old Carson but has less very slightly less contrast than current Carson lenses
• Off-axis flare suppression is slightly better on Carsons vs Edmund
• All three lenses exhibit excellent rectilinear performance
Carsons appear to represent the best balance in terms of contrast and flare suppression compared to other lenses in this control group. Old Carsons are no longer produced, and a larger "sweet spot" is desirable, but flare suppression falls short of current-production lenses. How much does all of this really matter? In a practical sense, higher contrast will yield better detection levels. That being said, the difference is subtle and slight but present.
