something to do wif stress on the glass..by placing the lens in a vertical position..the glass elements are rested in a flat position..some ppl oso mention abt placing the lens wif rear element down..but i doubt my 70-200 can stand still wif rear element down, so its always with the front element down..correct me if i'm wrong..
?
Then how do people store their long exotic telephotos
The elements are spaced apart and held by the construct.
Dun think the glass elements are physically stacked on top of each other and can migrate with different positions
The only thing perhaps is it might be unstable putting the smaller area down
