This is not an expensive lens. It’s been in production for over 20 years. You can still buy one new but I’m sure they are all just old stock by now. It was introduced in 1990. It’s AF is noisy because of non-USM auto-focus drive motor but that don’t mean it can’t take a pretty picture.

7 oz. and smaller than 2″x3″

I bought this from the B&H store in Manhattan in 2007

Made in Japan
