I won't classify TC's as lenses, but they do have glasses, and some of mine do have serial no, and tc with 'zoom' feature.
And so do the front add-on for tele or wide or close ups. They too have serial no.
These are in category not-stand-alone lenses.
Originally posted by slackercruster I got one question...how come 1200 of you viewed this polll and only165 of the 1200 bothered to vote?
I guess they don't know the exact number of their inventory.
Or they are unsure what to keep,
Or they are waiting more lenses to come,
Or some of them with fungus/not usable and might not categorize as lenses...
