What should I do with my old DSLR?

I have a Nikon D3100 that I used to shoot with A LOT I loved it, I have 3 lenses for it, the kit lens, a 55 - 200 and also a 35mm 1.8.

I slowly stopped doing photography as much and now mainly do videography with my Canon t3I which I also own a few lenses for.

Basically my point is, I like videography, so I likely won't ever go back to Nikon. What should I do with my nikon gear?

I was thinking maybe by a lens adapter so I can use my Nikon Lenses on the Canon body?

What should I do with the Nikon body itself? Seems like a waste to have it sit around doing nothing.

I would sell the Nikon body and buy a lens adapter so you can use the Nikon lenses on your T3i.

Sell all of your Nikon gear and use the money to buy more Canon gear.

An adapter to use your Nikon lenses on your Canon body would be a waste of money in my opinion.

Read the 2nd. Paragraph under "Overview" carefully.

Sell all your Nikon gear and buy the Canon gear you need. I assume you have the DX 35mm, and that is less than $200, so the whole shooting match would sell for a few $100.
