I am quite interested in getting a Sigma 135-400mm APO lens.
It is heavy... about 1.2 kg to be exact. Experience with heavy lens is only with the Nikon 80-200mm f2.8 that I do not use any tripod or monopod.
can I get away using the Sigma lens with a monopod at the extreme range?
I hate to carry tripod. If I do not carry any kind of mount, what would be the range and at what speed can I get away with a decent image??
