Somehow, I ended up with BOTH silver and black M.Zuiko 40-150 MSC lenses and one must go! Black is MSC, silver is MSC/R - they are identically fast in AF, the differences being the color and the pattern on the zoom and focus rings. Both are impeccable physically and optically - they have been babied and work and look like new. Front and rear caps included. US$150 for either shipped/Paypal US C$150 for either shipped/EMT for Canada Interesting trades considered - PM me. I have 500+ 100% feedback here and on eBay. Thanks for looking.
