What's wrong with my 70-200mm?
« on: June 21, 2013, 05:54:37 PM »
Hello guys

I have a small problem I was hoping you could help me with:

So today I bought a used 70-200mm f/2.8 IS (version 1).

I'm pretty happy with the lens as far as performance goes, but i noticed that there are 4 exposed screws where the tripod collar are supposed to be - these screws are basically preventing me from attaching the tripod collar.

I have attached a photo of one of the screws, and I was hoping someone could help me tell me why these screws might be there, or are they supposed to be there, and I am just being stupid? I wasn't able to find a picture of a 70-200mm online without the tripod collar attached so I can't see if it's normal.

Thanks in advance

These screws are guide screws to hold the collar on, your collar will only go on when it's lined up with these screws, offer up the collar and gently rotate it, it will slip on over the screws.

There is only one way the collar will line up, the four screws aren't evenly placed.  Just keep going til it slides on.

I'd probably do better to invest more time and less money.

Unless you do not have the original Canon collar, follow jims instructions.  If you look at the front of the collar, you will see the milled out openings that slip over the screw head, they only go one way.  Line up the red on the collar with the red dot on the lens and push it forward towards the front of the lens.  After slipping it over the screws, rotate it CCW so the black line on the collar aligns with the black line on the lens and lock it.
