Value for money and ease of use - Nikon D800?
I am looking at taking both still photographs and short videos of an owner build of a log house in the country. I want to be able zoom in on the video and show details of some of the build but I also want to show major steps in the process from a distance. As the scenery is amazing I want to capture this with stills and be able to take close-ups of key aspects of the build process.
I would prefer to have single camera which can take both good stills and good quality video but I am concerned about ease of use and value for money. The Nikon D800 looks like it will do both things I need but would I better of buying two separate cameras for about the same price as the D800. My wife is going to do a lot of the photography and she has very limited experience using a DSLR.
Darkcat studio advised that "Nearly any new dslr is capable of full HD Video, and all are still a compromise in that they do not offer smooth in-shot autofocus / focus tracking." I understand the D800 will provide a lot more features than needed but is the problem with dslr's in not offering smooth in-shot autofocus sufficient that I would be better of getting both a cheaper dslr and a video camera like the Canon Legria HFG25 HD Camcorder? The trade-off is against having to have two camera. As part of the filming process we are looking at travelling overseas and filming the supplier of our log house kit so I am trying to understand how serious the lack of in-shot autofocus might be when we are not looking at doing any sport style photography. Not much on the building site is going to happen very quickly.
Itai makes the point that you need to select lenses carefully to enable smooth auto-focus which I understand but can someone point me to more information why you must use MF?
