I bought the lens off ebay and the knucklehead seller didn't send it, even though it was in the description. He'll replace it but doesn't know what size it needs, and neither do I. I've searched high and low and can't find a reference, so if anyone of you kind folks has this lens and can tell me which cap I need, I'd greatly appreciate it!
Why don't I just measure it? Because I don't have a metric ruler and neither did the local Staples!
