I have this one or very similar to this and works fine with my Pentax. Should also work with Canon and Nikon and more. I have no connection with this site. YMMV.

Cool. But how can it adjust the focal length? Do they mean aperture?

It might work on some point&shoots but obviously, it can't zoom a DSLR lens.

There's not a lot of information on that page but I assume it is an infrared remote (meaning it's useless for the majority of pro DSLRs because they don't use infrared).

yes, it's infrared.

The Nikon D3100 lacks an IR port, so this won't work.
