    Default Canon and Nikon terms

    what is the terms use in Nikon for silent motor (Canon call it USM). is the Nikon 18-105mm with silent motor?

    In canon, only crop camera can use EFS lens, how about Nikon, what is the term use for EFS lens and EF lens?

    It's called SWM. 18-105 has SWM.

    In Nikon, crop camera is called DX and full frame FX. Nikon DX lenses are compatible to both DX and FX cameras.

    You should be more specific as DX lenses are not fully compatible with FX bodies. DX lenses can be used on FX bodies and works just fine but the image only falls on the center part of the FX sensor, so the usual crop factors still applies.

    Similarly, FX lenses also works with DX bodies, the crop factor applies of course.

    For Nikkor silent motor they call it AF-S like (AF-S 18-55mm DX) that is the DX (crop sensor or APS-C) lens for Nikon DX body also can be use for Nikon FX but will reduces half of the MP.

    Cheers

    canon:

    canon USM (ultra sonic motor)

    canon EF-S lenses (can only mount on APS-C bodies)

    canon EF lenses (can mount both cropped and FF bodies)


    nikon:

    nikon SWM (silent wave motor)

    nikon DX lenses (can mount both cropped and full-frame bodies, but automatically changes the FF camera to DX-mode)

    nikon [no designation/ lenses that don't have the DX designation] (can mount both cropped and FF bodies)

    18-105 is swm

    Not all dude. For some lenses you still can wing it... and still shoot in FX mode with DX lenses.

    Example...
    35/1.8 on D700.

    Wow, I didn't know that but why is the 35mm 1.8 able to shoot in FX mode? Is the construction different from other DX lenses?

    It's just that the projected image circle is large enough to be acceptable on FX...

    Oh... I see, that's why it works but definitely not as well as the 35mm f2 right? Because the picture alr looks very good

    There is some slight vignetting... but remember the 35/1.8 is sharper than the 35/2

    I regretted selling my 35/1.8... but one day I will buy it back I think.
