The Best Choice
After many comparisons, I found that Teds was the best choice. If something goes wrong, you have a physical store to return your goods and a company well known that will take the time to answer your questions. They have the expertise in the field of photograhy and are not just selling a great many different electrical appliances. The price of the lens was even better that many Ebay sellers. The Om1 price was excellent. All in all a good experience.
