>>3730652>What camera do you own that puts the shutter down when you take off the lens, timestamp it.All Canon EOS series as well as my SLRs from different eras.
Take for example the Minolta X-700, Zenit-E and every god damn DSLR on the market.
In (D)SLR cameras the shutter is allways closed and the mirror down unless you use some sort of lock up or take a picture.
Pic related, a Minolta X-700 SLR with the mirror forced open to make the closed shutter curtain visible.
