    This TC really helps. Although (manual) focusing is more difficult, especially handheld...
    Cheers! thumb.gif

    I was pretty shocked when I saw "handheld". I need to get a TC for my 100-400! Just curious though - Why manual focus?

    Manual focus with TC

    On 20D/30D autofocus only work with lenses with certain min f/stop value, which, I believe, is f/5.6. Since TC "steals" one f/stop, it essentially converts 100-400 f4.0..f/5.6 into 140-560 f/5.6.. f/8. And since I used the far tele side, at f/8 it killed AF ne_nau.gif

    There is a way to workaround this by covering certain pins with a tape (google for "TC pin taping", or check this dpreview thread), but I didn't try it yet...

    HTH

    I keep seeing posts on that but never really considered it would be an issue with L-Series so I didn't pay any attention to it. That stinks! :D

    Thanks for the tip and the link but I don't think I wouldn't have the nerves to try it!:uhoh

    L or not L, it's simply a body's limitation. If I'm not msitaken, 1-series have min value for AF to work at f/8, hence it's not a problem for them rich boys mwink.gif
