Quote: When one does a tethered shoot, should one see a "live" image from the camera before capturing the image? I don't get that, just an image once the shutter is pressed. I was hoping to see a live view to get "sharp" live focusing. Have I not turned something on - quite new to Lightroom?

If you have an HD television you can connect your camera to that with an HDMI cable. Whatever would normally be displayed on the cameras screen will now be shown on the television. The 7D is also capable of HD out (which some camera's aren't), meaning you'll get a very good quality image, making manual focusing a lot easier and more precise. Although saying all that, if the problem you're having is just with a 300mm lens with a 1.4X extender, then connecting it to a tv or a desktop computer won't really prove anything because you are better off checking focus accuracy over a decent distance, i.e. 25-50x the focal length.

Looking back, you were only using 1/100 of a second at 300mm with a 1.4x convertor, might that be a little slow even with a tripod? If it's (the body & lens) heavy & the tripod not completely sturdy, even walking near it might cause vibration? Might be talking out of the back of my head though
