Hi guys and gals,
I wanted to know if I mount a DX lens for example 18-70mm, on a file body such as F80, can it works? I understand it for sure can mount on but will I be able to use it widest angle of 18mm? Also will the metering works correctly? Thanks in advance. |

Unfortunately, even at 70mm, there's visible vignetting on a film body.

So in another words, if I own a flim and digital SLR bodies, it will not be worth to invest in DX lens liao. Cos flim body can't use it.

depends... apparently this serious vignetting only happens for the 18-70... most cost effective i guess
you would still want to have a DX lens for a wide angle solution for digital cameras unless you have a 18mm non DX lens.. then forget it |

![]() The other focal lengths look ok though. And apologies, but what do you mean by 'even at 70MM, there is visible vignetting'? I thought vignetting should be more visible at telephoto than wide angle? so more likely to vignet at 70MM than 18 right? |

The 18-70mm should not vignette at 70mm on your D70 - unless something else is causing it. Do you have a sample image ? Seems strange that you have vignetting at 70mm and not at other focal lengths - 'cos vignetting is more of a problem at the wide end. |

I've read somewhere that the maximum image circle is obtained for the 18-70 at 50mm.

![]() Anyway, please dun mind the quality of the content. These are 2 unedited pics of the same scene at 2 focal lengths. 34MM, f4, JPEG Normal ![]() 70MM, f4, JPEG Normal I can't see any vignetting on the 34MM shot, but I can see slight vignetting on the 70MM shot. Judging by the reponse, this is a cause for concern??? Hope someone can shed more light on this. |

That's light falloff. Are you sure you can shoot at 70mm f4 on this lens? This is a 18-70 f3.5-4.5.
Step down to f8 or more and see if its still there. |

Thanks guys! That's why I say Clubsnap is a good place for blur sotongs like me! I didn't notice the aperture thing cos it never was a problem for me on my old trusty FM2

Hi all. Since someone started this, i like to ask the similar question on Nikkor AFS 17-55mm f2.8 DX. I have been thinking about this for sometime. At what "mm" will this lens beable to use on 35mm film? Thanks.
