that is distance scale windows. (from the manual, p.15)

我估係有件零件工差有問題，轉到個位就有空隙，變成漏光。所以 48 同 55mm 都有。

不過，成萬幾銀既鏡，所用既部件都幾低水平。設計亦都好有問 ...

Thank you for telling me the real name, I never read the lens manual before.

左搵右搵

樓主可否解答下你話漏光，咁用野包住支鏡再試有無再漏光呢
因為我想知係反光定真係漏光

多謝樓主報料....小弟依指示做左
1. 係56mm...用電筒照...有漏光情況(左上角)
2. 係55mm...用Hood反方向套在Lens前端....無事
3. 係55mm....用Lens Bag套在Lens前端...無事
4. 係55mm....換上雜嘜lens cap....無事
5. 係55mm....再套上nikon original lens cap....無事

由24, 35, 50, 55, 70 都試過......都係一D問題都冇..............
再試下F2.8, S: 5'.......都係冇問題...

Yea, i think its the focus meter windows on the lens too, not VF~

樓主 係講 支鏡"對焦尺"上面那個窗~
唔係VF a...

*漏光位置在相片的左上角,有可能係 強光打入"對焦尺窗"中的漏光情況....

I can tell, I do the test almost at a very dark area, so I don't think will have any reflect light from other size, also this will easy be found at FX camera, if you are DX camera, you need to test at much longer time or your flash must be much stronger and obviously.

I found this problem because I use IR filter for the shot, so that is a daylight long time expose shooting, my test setting just suppose in same situation.

My 24-70 also got such a leaking problem as shown,just a very minor leakage but not as serious as the lens garfieldobox C Hing has .
setting F/8 8 sec M mode mf, range setting at approximately 55 mm distance as infinity.I bought this lens in July 2008,and I am not going to send it to CS for fix up.In case I need long exposure,I'll use a 3M black tape to cover the window.No big deal at all..

Can take letter from nikon cs, I don't think for this, they only say can be fix, what the useful to have the letter, is it can claim anything from them?

It may not happen on DX body depending how big the area of the "flame" as the DX sensor only occupy the centre portion of a full frame sensor.
