I am going to rent a Canon 400mm f2.8 L IS lens to use with a 1.4X or 2X TC to shoot birds. What is the best/safest way to support this lens on a tripod? I have a pan/tilt head but have not yet purchased a gimbal head. Can this lens also be used on a monopod, or is it too heavy?
Thanks for any advice or suggestions!:)
