Why don't I see professional photographers using the live view (the LCD screen) when they are doing shoots? Obviously, they are using a much better camera than I am (mine is just a Rebel t5i), but do the higher end dslrs' live view modes not take pictures as fast as my Rebel does (when shooting in live view)? Or what is the reason they don't use the live view mode more often?
I personally don't like to use the eye piece, I think because I am left eye dominant, I wear glasses, and I feel a little claustrophobic using the eye piece.
Ok, first a quick disclaimer, I'm an amateur photographer, not a professional - also, offer is not valid in all states, batteries are not included, your mileage may vary - ok, now that all that is out of the way, here goes.
I don't use live view for a few reasons actually. Most of what I photograph is wildlife and most of my shots are handheld. If I use the viewfinder the camera is well within my center of gravity and thus far more stable for my shot. More stable means a much sharper image. Holding it out far enough to see the LCD screen takes it outside my center of gravity, and that means lower quality results - especially in my case since most of my photos are taken with a telephoto lens.
Second live view has a delay factor built in - the delay will vary from camera to camera of course. For shooting portraits/landscapes etc the delay is short enough that it really isn't much of an issue - but if I'm tracking a bird in flight it can make things far more difficult for me to say the least.
Third consideration is battery life - using the viewfinder extends the amount of time I can be out and about taking shots because it takes a lot less juice from the battery than using the LCD screen.
And of course the most important reason for me at least - well, when I started using cameras they didn't have LCD screens. I've been using a viewfinder for so long doing it any other way seems entirely unnatural too me. Now the most important thing to take away from all of this - if you like Live View and it works well for what you do by all means keep using it. That's why they put features like that on a camera in the first place. What works well for you and feels natural for you is what is going to give you your best results. This is one of those deals where there is not "right" or "wrong" answer.
