GESO lunar lens test

Sat, Aug 9, 2025 10:11 AM

When I got home from dancing tonight I noticed that the sky was unusually clear, so I set up my tripod in the back yard, aimed at the most consistent telephoto test subject at my disposal, i.e. the moon, and took photos with the K3-III, mounted on the Bigma 50-500, DFA 150-450, and FA 250-600.  I then used lightroom to set them all at the same exposure (they were all bracketed) cropped them all square to the diameter of the moon, selected the best two of each lens, then also made virtual copies that I then applied lightroom's denoise software.  I then published them all to flickr at 1024 pixels, down from 1085, 1215, and 1462.

There were some inconsistencies, so my technique has some problems.  I also had some issues with SR vibrating things.

I was a bit surprised at how much weaker the bigma was than the other two.

Not ID-ed?  All a bit soft. Perhaps too much atmospheric haze. What was the shutter speed?

They are all IDed in each photo, but they are in the order listed sigma at 500, dfa at 450 and finish with the fa at 600. They are all at 1/200 and mostly at f/16

But, yeah, the air here is horrible. Riverside had some of the worst air quality in the country.
I'm a bit fuzzy myself this morning. I was up until 4, and gardeners were using a 2 stroke next door at 9.
