I am looking into it for a couple local commercials/shorts and my personal non skiing reels that I am working on, Along with it would be useful for interview stuff, and Why would I not need it on a T2i the screen is smaller on that then any other cameras.
I'm just starting to consider it and have not done alot of looking because i am hesitant on if I would use one but i have had problems On a couple from car shoots as well as anything where I am cant use a viewfinder (ie slider shots, tripod pans, etc).
And eheath, I have not looked much on EVFs but I definately like the idea the dp4 looks pretty solid and I like the basic controls and headphone jack so That is a good option. My main concern on it thou is size because I want to be able to just look at the monitor and know what is in my shot and if it looks good exposure wise and color wise but at the same time I dont want to carry around a huge thing so do I go with the dp4 or 6? anybody have experiance with what size is good?
It may be overkill for me and if its not something I need, I dont want to get it but I feel that it would benefit me just because The screen on the T2i is so small and It would make monitoring motion much easier.
