albnok : Just wanna ask.. I got a 24-85mm Minolta lens that is having some focussing problem. Sometimes it's sharp, sometimes it's not. The distance indicator on the lens is also all off - you see the window but the indicator label moves all the way out of the window when the lens is focussing.

I suspect the gearings has some problems, can Cheah Camera fix it if I send it there?

albnok : Sorry but I didn't notice you yesterday. I guess I was kind of zoned out then... was having a bad day yesterday.

Oh, I think I got a speck of dust somewhere on my A850 focussing screen. I can see it when I look in the viewfinder but it does not appear on the pic. I've tried blowing the mirror but the speck is still there. It is not on the viewfinder glass. Any idea how to clean it? It's just annoying to see it there when I look through the viewfinder.

*sigh* Last night I was using the blower to blow just about every inch of lens mount cavity in my A850. Even popped out the focussing screen to blow into the prism area and still that stubborn speck of dust or whatever it is, remains firmly stuck to its place!!!

Seems like I am just gonna have to live with it. I just dunno where it is. Can't see it on the mirror or anywhere else. Good thing is that it does not appear in the pic...

Anyway, thanks albnok for showing me how to unlatch the focussing screen.
