Originally posted by podboy3 Will a Sigma SD9 or SD10 work on a Pentax? I am not very "up" on this stuff but I do know there is some kind of connection between Pentax and Sigma cameras......So if there is a connection between the two I would something like the hot shoe make the list?
I would very much doubt it, you can get SIgma flashes for Pentax cameras, but they would have to be designated for Pentax and not Sigma.
Currently flashes like the Sigma 530 or 610's will work with Pentax, Canon, Sigma, Sony, Nikon etc, but you have to buy a specific model to suit one or the other, they are compatible between makes (although that would be good)
