Nose up minimizes the oil-on-blade problem.
Autofocus lenses, especially of the AF-S generation, use little or no oil or grease. The bearing surfaces are essentially low friction self-lubricating types. Migration of oil is unlikely to be a problem no matter how the lens is oriented in storage.

I was told that the best way is keep them standing on their mount end. It reduces the probability of having oil in the aperture blades. And we also need to avoid heat and moisture on them.
以前人家跟我說,最好的擺法是接點朝上。這樣可以減少潤滑油跑到光圈葉片的機會(依據後文,這邊說的應該是是手動鏡)。同時我們也應該要讓光圈葉片避開熱跟濕。

接點朝上收納可以最小化光圈沾到潤滑油的問題

對自動對焦鏡頭來說,尤其是AF-S的鏡頭,幾乎是沒有用到或是只有一點點潤滑油。對焦系統基本上就已經是低摩擦度材質。所以鏡頭不論怎麼收納,潤滑油大概都不會有受到地心引力的影響的問題(呼應前面說要接點朝上的說法)
