Help with focal length stuff.

[lisacollins]

First of all, I know this is probably placed in the wrong part of the forum. My bad for that. I didn't know where else to put it.

My boyfriend is doing a project in school and we are trying to figure out the focal length of this photo: http://i169.photobucket.com/albums/u...rex__/room.jpg

Do you guys have any guesses? Please and thank you in advance.

Looks like it was taken with something in the 16mm range. I have a 16-35mm and have taken the same type of wide angle shots.

Yeah, I was thinking somewhere around there as well. Thank you! =]

I'm thinking a Sigma 12-24mm may have been used. Not because I have one but because of something about the ultra-wide view and the way it handles barrel distortion look familiar....just a hunch

I'd guess something like the 10-20 on a crop body, or 12mm on a FF (it looks notably larger than 90* fov to me somehwere around 100-110*) but that's speculation. I have no idea what camera was used, the resulting crop factor, or if the image was cropped in post.

If you can find any of that out THIS might help
