Hello,
Yesterday when I was playing with the DA 70 Ltd quick-shift, trying to take a photo of some sakura, I discovered that its focus ring was very stiff at close focus.
I wonder what could be the reason and if there is a way to fix it (though I'm not sure I'll have the courage to break down such a delicate lens, I did once with a S-M-C Takumar 135 trying to fix its infinity focus problem, and it never comes back to life again
) This is my favorite lens so I'm a bit upset, and also a bit worry it could get more troublesome later on.
I bought this lens over the Internet last summer, its physical status and image quality were great, and I almost never do manual focus or quick-shift with this lens, especially at close focus, so I don't know if it already had this problem by the time or not.
Thank you very much for any help
