Actually, I've never had a problem focusing to infinity. With the helicoid racked all the way in, it acts just like a "regular" 2X TC. But, with the helicoid racked out to various degrees, the lens/TC combination gets into macro focusing ranges. Fred - This message is from the Pentax-Discuss Mail List.
