before replacing it? The story is that I lent my D2X, my Sigma 28-70 f2.8 + SB800 to my good friend & neighbor of 20 yrs, so he could shoot his daughter's beauty pageant. Ya, I know, what am I nuts!!? I really didn't want to go, but was willing to edit the pics for him, so I went ahead & lent it to him. She WON, btw! Well, anyway, he returned it while I was sleeping that night, and the next morning, I noticed the DK-2 assy was missing off the cam. DAY-IM! :evil: Just got the replacement parts, some 5 days after it came off. Been using it without anything on it since it became MIA, and beleive me, THAT's a pia! So, do I need to clean anything before putting the DK-2 back on? What behind that eyepiece anyway? Looks like another piece of glass in there maybe? :? Is it te mirror? If so, what, & how do I go about doing this?
