    I have a Nikon AF 70-210, a Sigma 28 mm 1.8 (I don't think this is AF), and a Sigma macro 2.8 that is AF. I have not used these lens much since I got my Sony digital a couple of years ago but they all worked well. I used the Sigma 28 mm on my AF Nikon camera but I guess I used it on manual. The lady at the camera shop was very helpful and not pushy but she thought at first the camera may need the "D" series lens to make it work properly but Nikon said not. Do you think the Nikon AF 50 mm 1.8 lens would be better than the Sigma 50 mm AF 1.8 lens?? I love everything Nikon makes - I have two Nikon film cameras but have been pleased with the Sigma lens that I bought.

    I don't know any 50mm f1.8 Sigma.
    Your Sigma macro lens will still be worthwhile, no reason to not use it. The 70-210 Nikon is also still a fine lens in its class.
    The non autofocus 28mm Sigma may be not of much use on a D50, I think.

    Do keep in mind that due to the smaller sensor compared to 35mm film the field of view is more narrow on all lenses, so to understand what field of view you get, multiply the focal lengths with 1.5.
    So a 50mm becomes a 75mm lens in effect.

    If you want to have a lens with about the same field of view as a 50mm lens on your old SLR, check out the 35mm f2 Nikkor, or the 30mm f1.4 Sigma. These can be considered to be the new "standard" lenses on 1.5 x crop factor cameras like the D50.

    To give you a wider focal range (which you lost due to the crop factor of 1.5), you could do worse than getting the cheap but optically surprisingly good kitlens that belongs to the D50, the 18-55 kit lens. It will allow the same field of view at 18mm as your old 28mm Sigma gave.
    (18 x 1.5 = 27mm)

    I will absorb all you have told me when I return in a week. I am going to Nova Scotia and look forward to taking photos.
