Again. Exactly which model lens are you using?
It seems that you may have an old lens that works with old cameras, but not a relatively new camera. Sorry, but that is a lens problem. Old lens does not work with more recent camera body.
BTW, you might not need to enable releasing the shutter without a lens. It should not make a difference, though.
Thanks @waddizzle and everyone else for your input! It seems I should not have went with a third party on this and a newer lens. I am going to send this back to B&H and trade in my 17-40 using this money to get the 15-35 RF 2.8. It wont be backwords compatible to my older bodies, but I can only use one lens at a time anyway!
