| I picked up a doubler loooooooong ago, don't use it much. It gives more zoom, yes, but tends to throw the focus off a tad. Also have a 420-700mm manual-focus lense that is WONDERFUL, except planes tend to move a tad bit faster than I can manually focus/compose/shoot. That one only comes out for special occasions and static subjects. I think the last time I used it was back in '98, when they moved the USS Missouri over to Pearl Harbor. It anchored off the coast of Waikiki overnight before being pulled in to port the next day. I drove down with my then-girlfriend to see it, and ended up with the 700 on my camera. Had to back the lense out a little bit from full zoom with the doubler on the end! Dang. Now I'm gonna have to go dig out some of those pics....I happened to be in the shipyard the next day when they towed it in. The shipyard made a special allowance for cameras to be brought in, as long as nothing classified was recorded. I was able to use my 35mm lense to shoot the thing we were so close!
Sorry 'bout the thread hijack....
