I was somewhat surprised by the detail from the R5 using a shorter lens. Did you crop to match the 840 reach of the Sony? Or do you attribute it to the sensor size pulling in more detail?
Kick butt stuff man...love it. So question with the owls are you more or less standing exposed in cover or using any kind of blind? These guys look like they get pretty close!
