I picked up a Manfrotto 3021 Pro tripod with aluminum legs and 3030 pan tilt head in 2003, for mostly shoot night scenes and landscapes but want to shot more birds, wildlife, and action photos.
The Sirui K-30X and Wimberley Sidecar are on their way for use with my Canon 100-400 mk1 lens. My thinking is that this would afford the most flexibility with the 3021 tripod.
How easy is it to adapt from a pan tilt type head to a ball head for landscapes?
Does it make sense to replace the 3030 head with the Sirui ball head with sidecar, or should I consider getting a second tripod for the Canon lens, and keep the old Manfrotto setup intact?
