    I can't figure this one out. Could someone explain it to me please?
    I have a D80. I love my 50mm but need something wider.I was considering the sigma 30f/1.4. Then I read this on photozone about the lens:

    "The AF 30mm f/1.4 EX HSM DC is one of Sigma's Digital Camera lenses designed specifically for APS-C DSLR. It has a reduced image circle so it's not compatible to 1.3x or full-frame (D)SLRs"

    What does that mean? Will it be even wider on my D80 than for example 30mm focal length from the 18-135 or just the opposite?

    means it will work just fine on your d80 like it does on my d40.....enjoy..;-)

    it will be the same 30mm as 30mm is on your 18-135
    it is not designed to work with full frame bodies
  4. Yes, it will be perfect on a D80. (just not a D3 or D700)

    It will work fine on your D80, since it is an APS-C DSLR.
    It will be exactly as wide as the 30mm setting on your 18-135.

    However if used on a D700 or D3, since the sensor of those camera's is larger you would end up with dark corners since the lens is designed for a smaller sensor... unless these cameras are used in APS-C mode, which they can, albeit a corresponding reduction in pixels for rhe captured image.

    thanks for the quick responses. That makes sense.
