Diana lens adaptor on nikon d3000?

Hi! I have a Nikon d3000.im trying to figure out how to use the diana lenses with this camera, so far: the lens adapter and the lenses don't really stay on all the way, and all the lenses look pretty much the same. (there are 4 different ones, i can't tell) also, i can only shoot in manual. I can adjust the shutter speed, but is there any way to shoot in any other settings? Btw, the camera doesn't recognize the lens (its plastic so of course it won't) but can i bypass this in any other setting? Anyone have experience with this?

Remember to follow the instructions in your user manual on how to set up your camera to use Non-CPU lenses

The Nikon D3000 is a fairly decent camera, even with its basic kit lens. Don't waste your time playing around with Diana lenses. They are little more than plastic garbage. You will likely never be happy with the results.
