just to get this off the ground from a member.
i use a canon 350d
with a sigma 50-500mm.this week i got a kenko 1.4x 300 pro converter,
i also have the kit lens the 90-300mm which i have not used since i got the sigma,but now thinking of using it with the converter for flight shots,as it will be easier to handhold.
winter is here so not much time to get out
