Ronald Reagan Presidential Library and the AirForce one plane from around a mile away.
One evening I hiked Mt McCoy in Simi Valley. From there you can see the Presidential library which around a mile away. I had my Canon EOS-M and an old Sun M42 80-210mm lens which I wanted to test. I had got that lens for around $20! I didn’t have a tripod but used a bench to make my camera steady. I think the camera and the lens did a super job. You can even see some function going on inside.
