Manual Focus sticking
Sep 1st, 2017 at 8:40am
 
The Manual Focus of one of my lenses is getting stuck when I try to move it.
After several attempts it does move but then gets stuck again.
I've tried using a blower on it but it is not blowing away the grit that seems to be stuck in it.
Does anyone have any suggestions as to what to do ?
Thank you

Which lens John???

If there is a gap in front of the lens, try cutting a piece of cardboard into a triangle (the thickness of a photo)
Then put one of the pointy ends into the slot and move it around the barrel.

Looks like you got a bit of grit/sand in the focusing ring..

I have done this with a zoom lens and it freed it up.

Dont know if i explained it right, ill try find something to explain it better.

Never attempt to blow it, as it blows it into the lens and might clog it up more.

Its a 16-35 2.8L.

Thanks a million John - I'll have a look at those options and get back to you.

Looks like I'll have to take it to Dublin to get it cleaned.
