most of you guys handhold to pan or take sports shots or do u use monopod for more stability?
I use a monopod with sports shots. I pan with a high shutter speed so as to not blur the background since my clients want to see it for dog sports but I use a very narrow 200 f/2.0 lens to knock it out of focus. For motor sports I would slow the shutter down to allow the panning to blur it when desired.
