This is a special version of the 055MF3 MagFiber tripod with the features most commonly requested by birders and nature photographers. Compared to the standard MF3 model, this doesn't have the PRO top casting (not normally used in conjunction with fluid heads and spotting scopes) or the split center column (again because low angle shooting isn't as useful for birdwatchers) but does have all the advantages of carbon fiber plus the leg warmers that help make carrying the tripod around more convenient in extreme weather conditions or after a full day out in the cold.
