I picked up two lenses off of Ebay a few days ago and they both arrived today.
I had been wanting a teleconverter lens, and decided to take the plunge with a wide-angle as well.
The reviews on both lenses stressed how large they both were -- and man, are they!! They both weigh in at about 1 pound each, and it's all I can do to pick them up with one hand. The "dinner plate" description that I snorted at suddenly doesn't seem so funny...
