Zoom

Hello, I have to take pictures in attics of straps and they are usually about 15-20 feet away. the lighting is also not great.
what would be the best camera for this job to zoom in on these straps

I don't know how big those straps are, but would think something like a Canon 60D with a 70-300 lens and an external flash would be sufficient. The straps probably wouldn't fill the frame at 20ft but unless you're planning on printing posters etc, some cropping shouldn't be an issue.

You can also refer to this focal length calculator here, a bit down the page:
