Again, first of all, thanks to Susan P, Atkinson, NH, who sent me this lens (580028yi) for review.
To be horniest, I have not used or even tested it. But with it in my hands, I want to tell you the following about it: made in Taiwan; with a plastic mount; macro 0.38m (1.3 ft); lens' length changed with focus ring turning (no so-called 'internal focusing'); shortest lens' length at the middle between 35 and 80 mm zoom and longest at 80 mm; sealed rear glass piece on its bottom (this glass does not move with zooming, meaning no dust comes into lens body from this end. Good!).
