My friend has this adapter with canon lenses, but he mentioned something that the picture is up side down when adapter is on??? i guess the viewing system is messed up?? Also he mentioned that I will loose two stops of light.. I guess it is because of the lenses that he has. Also he said it is imposible to handheld it . Is it something about all adapters that you can't really handheld for a good picture?? Will that m2 redrock setup for 1300 include everything I need except lenses and camera??
