Just wondering..Any nikonians crazy over manual nikkors like me and still use them?

Interesting from your photo that the rabbit ears have been removed?

No, CA has got nothing to do with flare. It is the inability of the lens to focus light of all colours to a point, so you will see colour fringing on hard edges in your images.

You might have gotten one of those early copies which actually have an ED element that is not acknowledged by Nikon. That may explain the sharp performance of this lens.

Maybe the non-ED copy was using fluorite element which Nikon later discontinued using with the development of the ED lens.

erm.. what manual lenses can meter and have focus confirmation (the yellow focus light) on the D80?

Isn't the fluorite belong to canon coating.

I have chance to use the 180mm it seems the output is the same of the AF version :dunno:

All AI/AIS cannot meter on the D80.

All will give the AF confirmation on D80.

Get a body with coupling like the D200 for both.

I get both with an adaptor on a canon body instead

thanks XC!

Fluorite doesn't belong to Canon. Fluorite (calcium fluorite) is a naturally occuring crystal which exhibits low dispersion characteristics. Many lens makers are using fluorite for their APO lenses. Nikon later developed ED glass because fluorite is too brittle. ED and fluorite are not coatings, they are the glass material itself.

Look under ED.

Thanks for the good info.

Actually, even the ED elements are still not that solid. Note that they are never used as the first element, ie, exposed to the exterior.

*gasp* you are right.. Like in the AF-S VR 200/2IF-ED, AF-S VR 300/2.8 IF-ED, AF-S 400/2.8 IF-ED II, there is still a plane element in front, otherwise it's always the 2nd element.

The front element is always a protective normal element - replacing that front protective element if it gets damaged will be cheaper than replacing the ED element if it gets damaged. Does not mean that the ED element is not solid.

You got a point there. :think:

Normally, not just the front element, they change the entire front element group. The lenses are distributed in sections, they replace the entire sections together.

Yeah, you're right that they change the entire group of elements together, but usually the front protective element (at least for the 200/2, 300/2.8, 400/2.8, 500/4 and 600/4) is in a separate group of it's own (actually the front protective element and the rear one as well are not even mentioned as part of the lens specs eg. the 300/2.8 has 11 elements in 8 groups, but has 2 other protective elements, 1 front, 1 back, that are not included in those specs)

Yes, those excluded,

aiyo! you know or not. put ED on front element for what?!!!
gosh! ED is to control dispersion of light and it's critical at the central and rear group of elements.
light bending/focusing occurs mostly in the central and rear groups.

For tele lenses, it's the front element that is most critical, that's why your aperture is determined by it's diameter also, IIRC the centre groups are for spherical aberration control.

man. this is getting out of hand.

change of topic.

1.Recently got a 105/4 macro and looking at the PN-1. But I cant get the camera to set the correct aperture when both is fitted on. Any ideas? I got both to switch apertures but then the camera doesnt reflect correctly.

2. 105/2.5 I can get a good condition one at a very seductive price. but how is it compared to the 85/2 which is like commanding 2x the price.

 

[XC Pictorial]

85/2 commands 2X the price

I always thot.. and also gotten the 85 cheaper than the 105f2.5..

but price abit sensitive to discuss here perhaps u can PM me see if i can provide any advice

Try the 105f1.8 it can beat 85f2. :thumbsup:

 

[TMC]

too expensive. looking for cheaper value for money lens.
