Live view vs View Finder

Maybe this is well known or is it just my camera/lens - 7D and 24-70L

If put something small, say a doorknob, dead in the middle of the VF and take the picture, when I view the picture in playback on the rear LCD and zoom in fully the subject is right in the middle of the picture, as expected. If I do the same but use the live view LCD to center the knob in the picture (using 10x zoom to be sure of centering) and shoot, when I playback that picture and zoom in fully the knob is off center low on the LCD, almost out of sight. What gives?

At first I assumed i had flinched and caused it myself but I have placed the camera on a solid surface and checked a dozen times.

In live view you can move the little window around. When you zoom in to 5x or 10x you are zooming in where this window is located. So, if the window is not centred you won't be framing in the centre either.

Did not know that. I will check. THX

That's exactly what it was. I must have bumnped the joy stick.

Ah, cool. I never noticed that feature. Playing around with it on my T3, I didn't notice any way to make it snap back to centre. (However, my battery was apparently dead and I didn't feel like digging the spare out while and just tossed the dead one on the charger.)

Fun feature, no idea if I will ever actually use it, but good to know about it. Thanks.

You will definitely appreciate that feature if you use AF lenses while shooting with live View or if you shoot videos as you can select which area you want to AF on!!
It is especially helpful if you also use MF lenses as you can zoom in on whatever part of the FOV you want and get precise focus with MF lenses..

of course while shooting video, it is useless imho...I would definitely recommend an LCDVF for your video shooting...it makes things so much easier and focus is easier to hit as well..also you cannot use the zoom feature while recording (AFAIK)

Cheers!

Honestly the only times I've been shooting with live view so far have all be astrophography, where I'm trying to get a centre star sharp anyway. And with a T3, video isn't something I rush out to do. But a new body is in the future, so no idea if that will change.

10x zoom on liveview is very handy for manual focus on a tripod, have used it for long exposure night shots. Autofocus doesn't work reliably in such low light.
