Experimenting with Manual - 05 Jan 2023
The only significant changes to the camera I made was to switch the Aperture and Shutter dials so that Shutter speed could be adjusted with the front dial. The rear dial would be kept at f/5.6 at all times for the Sony 600/4 + 1.4TC. I also enabled Zebra Settings (Custom 2 / +107) to highlight overexposed areas so that I can easily change shutter speed or ISO to remove the overexposed highlights.
I then took a drive to Elizabeth Park to play with the camera and see if I could handle "Manual" operation. With a gazillion squirrels around I tested the camera by first pointing the lens toward the bright sky and adjusting ISO so that the zebras would disappear (ISO 2500 at 1/1000 sec at f/5.6). I then pointed the camera at the squirrels and adjusted shutter speed if necessary.
Exposure appeared to be good enough, so I drove over to the Detroit River International Wildlife Refuge to test the exposure range on both ground and tree objects. These asters were a bit on the dark side. The sky (and nest) was properly exposed, but the woodland trees were also a bit dark, but not too bad.
A flock of Eastern Bluebirds flew through the short loop trail so I got the opportunity to test adjustments. The front dial made it easy to adjust shutter speed to optimize exposures.
Optimal exposures occurred when shutter speed was dropped to 1/320 or 1/250 sec at ISO 2500. I'm happy with the results. I will go back to Aperture-Priority and Auto-ISO when the weather is really cold as my fingers won't work well, but I'll be trying this Manual stuff again!
