Zoom feature moves smoothly and stays in position whether you're pointing up or down. No dents or dings, and the glass is clean and unscratched without fungus or haze, though it does have some internal dust which does not affect image quality. Original Canon Caps and soft case included. I have not tested image quality, but I did check for oil on the blades (none), and it does stop down properly through the scale from f/5.6 to f/32 in half-stop increments when attached to the AE-1 Program I am also selling on eBay.
