Where's the remote???

There is one more item I want to mention on the subject of getting a sharp image. Besides using the mirror lock up and 2-second delay feature, I use a remote release to trip the shutter. There are two types produced for the Canon series of DSLR cameras, one is corded and the other is cordless. Unfortunately the infrared sensor for the cordless remote is only on the front of the camera. It would be convenient for landscape shooters if a sensor was also placed on the rear of the camera. Either one you choose will help to reduce potential camera vibrations by keeping your finger off the release button.
