Dude the targeting pod on the tomcat is a much earlier version that what the eagle has, the sensor is a much lower resolution. You can’t compare the two.
It also uses digital zoom when you zoom in to the highest level so it’s not using lenses but just blowing up the digital feed on the screen, rather like those crappy digital cameras that came out in the early 2000’s.
It’s all part of the charm of using old kit.
