1D Mark III, 100-400L IS + 1.4X
Jim, I suppose one reason to use the 100-400 with 1.4X for a stitched pano would be to make it easy to "lock" the focal length at 140mm (the minimum for the combo), but...that lens can be pretty well locked with the zoom friction adjustment, so why not use the bare lens? Doing other shots at longer focal lengths? Gear junkies want to know! Believe me, I've used zoom/extender combinations at FLs that could be gotten with the bare lens. Sometimes there's no time to remove the X, or it's not worth the trouble. Just wondered what your reasons were.
