hello, group-members!
i was looking at a tempting offer for a sigma 170-500 telephoto lens, when my friend came up with the idea of a teleconverter - a 2x converter would make my 28-200 work as a 56-400!
since the cost of the converter is less than a quarter of the cost of the telephoto lens, i wanted to know - is there any reason why i should be opting for the latter? are teleconverters known to have any problems?
