A remote switch is almost essential for
good macro photography. I have the wired version, RS-60E3.
An alternative to using a remote switch is to load up the
software, connect the camera via USB and see on screen what you are photographing. You can set images to go direct to the computer. You can zoom in and adjust the focus in detail, and a depth of
field preview is available. You can also adjust the main variables, like aperture, ISO and exposure compensation, with the mouse. The only thing to watch for is vibration, if your computer is on the same table as the coin, as mine is - I hold the mouse in the air for the final click! It shows very clearly how
still you need to be when taking the pic. Hold your breath.
If you are going to use the
software, first
search the Canon site and get the current version, then
search again for the manual for the current version. The disk that came with my camera
had old versions, and the manual provided did not match the
software version. Read the manual before installing, and install before connecting the camera. Install what came with the camera, then update it with the updater from the Canon site. You can get the
software update here:
http://software.canon-europe.com/products/0010610.aspIt's the EOS utility updater. But there must also be a site for the USA.
Also, If you have not done so already, you should check the firmware version on your camera and update it if necessary. You should have version 1.1.0, and you can get it here:
http://www.canon.com/eos-d/index.htmlGet the instructions too.
Drawbacks? The remote switch does not
work when you are connected to the computer via USB, and I haven't found a way to use autofocus while connected. Also, images you want to use for custom white balance might end up on the computer instead of the camera, where the camera can't see them, so you might have to disconnect to set up cwb.
