5D2 Video focus technique
on Apr 6, 2011 at 7:29:10 pm

Hey guys and gals,
I'm new to this forum so first I'd like to say hello.

So my question is, when taking video with an SLR how can I setup the focus where everything from lets say 6 to 10 feet out to infinity is in focus?
Do I need to figure out the hyperfocal distance for the focal length used and set that up? I have a DOF calculator for my iphone and it tells me the hyperfocal distance for a specific focal length.

The reason I ask is because I've seen a few videos taken with SLRs and I noticed everything is in focus without the used making adjustments, so I'm trying to figure out how they do that.

Thanks
R.

If you close the iris of the lens then this will increase your depth of field which means you will have a larger area of focus in your shot.

Get a very wide angle lens and shoot at a closed down aperture. It's all about the optics. But then again the whole reason to get a DSLR in the first place is *shallow* depth of field. If you want everything in sharp focus, a standard fixed lens 2/3" camcorder will be much more what you're after. Sony EX1, Panasonic HVX200, etc.

I agree about the role of the SLR, I just want to maximize what i can do with one.

So maximizing the focus area is as simple as shooting with a wide lens and a large F stop?

It's an issue for those who shoot weddings. When the bride is coming down the isle, you have to keep the F-Stop at a high number, 6 or higher, and it will help keep every thing in focus. Also, set your focus ring to the infinity setting. Setting up your lens to a lower setting like 1.2 - 2.8 will give you a shallow depth of field.

Brent,

Just out of curiosity, what stabilizing gear do you use with a DSLR in a wedding situation when the bride is coming down the aisle? I purchased a shoulder mount, but I'm not in love with it.
