===================================
NOTE:
This video is a re-edit of my upload years ago and may show low quality footage, the pictures included here are much clearer. My copy came with plenty fungus and output may also be affected by cleaning (coating might have deteriorated) and age; however, the lens has pleasing output and sharp at f/4.5 at any focal length. I did not intend to shoot video at the time and did not bring a tripod.
