Re: Parfocal not so important in WIDE-NORAL zoom as in Telephoto Zoom

I disagree, if you ever shoot SPORTS, that total 3 ~ 6 seconds lost due to camera re-focusing after changing zoom range is DEADLY. Its the difference between "getting the shot" versus losing all the shots.

I don't know where you're getting this figure. The adjustment happens pretty much instantaneously as you're turning the zoom ring. I can't feel any delay.

Unless you're pressing the shutter button quite literally as you're turning the zoom to get some special effect, it doesn't make any difference.
