Testing out the "new" old zoom lens I bought last month, the 75-300mm f/4.5~5.6 AF Nikkor, introduced in 1989,discontinued in 1998. Both shots hand-held at f/11 at 1/30 second. 300mm on both.
In-camera zoom + slow shutter speed.
Shot at f/11 at 1/30 second, and the push-pull zoom collar slid back,toward me, starting at 300mm, and ending at perhaps (???) 135mm...not sure, really.
