I have been considering attaching my tablet to my canon camera either by wifi or by usb cable. My intended purpose is to better be able to see my compositions and then to shoot remotely. I know I still will have to manipulate my camera. I shoot primarily landscapes and I find when I get home that I usually miss stuff "growing in" around the edges of the frame I thought that if the picture was bigger then it would be easier to see or harder to miss as the case might be.
questions are
1. will the feedback to the tablet be such that it is practical to shoot this way or will there be a huge time lag
2. does anyone here do this same thing

I have two mono pods. One is a Gitzo (no model number) that is over 20 years old. It's aluminum with twist locks and extremely heavy duty. The main "barrel" is 1" in diameter and the smallest is 1/2". It extends from 19" to 63". It'll hold anything you can put on it.

My other one is a Manfrotto 685B. A spectacular and innovative mono. No twist locks or lever clamps. You press a "trigger" and pull and it expands to 67". Also has a fold up foot lever so you can easily raise and lower to any length with the press of the trigger. It's my go to mono because it's so easy with no muss and fuss of twists and clamps and smooth operation. The only issue is collapsed length - it's 29 1/2" so it won't fit in some of my luggage. Look at it on-line. I'd recommend it to anyone that wants a quick, infinitely adjustable mono. And it will handle any weight I can hang on it (D800E and 70-200 2.8).
