Yes, I use a number of old Zeiss lenses on the EOS 6D and 7D. Since the 700D has the same bayonet, there won't be any problems there either. However, the lenses can only be used in M ​​or Av mode as there is no autofocus. The adapter fits well on C/Y lenses but is a little difficult to remove due to the lack of a release button normally found on Contax and Yashica cameras.
