Default Indoor full-length portraits and focal length?

On a 20D body, a lens somewhat wider than 50mm is clearly the ticket when attempting full-length portraits in less than spacious indoor situations. What do you those of you with pertinent experience consider a good choice of focal length that avoids obvious wide-angle distortion issues under these conditions?

regards,
Terry

I use my 24-70L. I think I usually end up around 35-40mm.

It really will depend on how much room you have.

O.K., I guess I'll have to come up with some parameters, even if they're only theoretical for now. Let's assume I cannot back up any more than 8-10 feet or so; will a 28mm lens on a 20D give me a full-length shot of an average person, or will I need something wider: say, a 24 or 20mm? And will there be any significant degree of wide-angle distortion in the subject with any of these three focal lengths?

regards,
Terry

You would need about a 30mm for those measurements and your crop, I think.

I think the 35mm f/2 would be perfect for that =)

Download this Excel file.
On the Depth-of-field sheet tab, it will give you the field of view depending on your camera, lens focal length, and distance.
