Canon SLR camera lens is a bayonet? Can you use a domestic lens?
Is the bayonet, but then back, with the screw lens camera has been very rare
Canon's bayonet size is Canon dedicated, deputy factory also has, but to Canon authorized Caixing, deputy plant is mainly Dragon, Tuli, Sigma, etc.
Any domestic one can not be universal, but can be transferred through the adapter ring
Canon's bayonet is the EF bayonet as long as the Canon can produce other manufacturers of the dragon with the Sigma is compatible with Canon's bayonet
You can tell me the body model and then what the price of the head to do with what I recommend to you
Canon SLR camera is bayonet - Canon EF mouth.
Canon SLR camera from 1987 to EF card mouth, only Canon 1987 after the production of EF mouth or deputy factory production EF mouth lens can be installed directly. Even Canon's own lens, if it was produced before 1987, non-EF mouth of the lens, can not be directly connected to the Canon EF bayonet camera body.
China's domestic production of all previous SLR lens, there is no one EF card. China's production of SLR cameras only Phoenix is used PENTAX PK bayonet, that is only only Phoenix SLR lens can be used in the Pentax body.
