    cant say for certain but the adaptor may not have the proper connections so may have to use it manually

    iv'e had it in manual and it won't let me set aperture or shutter speed ,it lets you focus with it but when you take the shot its just a black screen no pic taken.......

    I also have a tamron adaptall lens mine is a 28mm. If your lens worked ok on a D5000 it will certainly work on a D3100. Set your mode dial to M then set your aperture on the lens, then it's just a matter of working your exposure time till you get an image

    The aperture should be on your lens. Because this is a manual lens the camera wont recognise it

    I just Googled your 500mm mirror lens. Under the Tamron 500mm 1:8 (on the lens) you will see a lot of small numbers these numbers are your aperture for talking sake move it to 5.6 look for a green dot below the aperture numbers. On the camera to the right of the flash you will see a wheel with M.A.S.P. line it up to M, then take a shot, If the photo is too dark wait till the dark photo goes away then press the ? button once then move the control button to the left this will make the photo lighter
    you may have to do this a few times till your happy. If it's too light just move the control button to the right. Hope this helps... Graham
