Dropping a Canon 24-70mm lens...

    Friend of mine has just done this and is pretty concerned about the potential damage done. Lens was attached to body and the lens hit the tile fist, probably a couple of feet. So far it's working okay - zooming in/out okay, focusing okay etc...but there's a slight bit of damage to the top of it and it's hard to get the lens cap on/off.

    What internal damage could we be looking at here? Cost much to repair?


    Thanks.

    Thanks, I see he does repairs here. Have taken note. But from what I've said, does it sound bad? Person could do with a little reassurance!

    it's as good as new, nothing wrong with that lens. Get the top off a tube of Pringles and sleep tight.

    Is it still working? Does it auto-focus and zoom ok and is there any debris when looking through it?

    If it still works then don't worry about it. Simple as.

    I recently had my 50mm 1.8 caved in. The section that moves when it focuses was at a 30-odd degree angle and there was debris visible when you looked through the lens and when you tried to use it to auto-focus it made an audible crunch. I just wrenched it to the side, straightened it all up again and it works fine now. Actually seems to focus a bit faster...

    Seems like the filter ring took the hit, could have been weakened the lens a bit.
    main things to look out for would be:

    Are the zoom and focus functioning smoothly? (possible barrel distortion from drop)
    Is there any noticable softness on one side of the image? (possible that the front element could be pushed in slightly)

    if you use filters then they probably will get stuck and be a problem to remove without smashing them.

    A new filter ring would probably cost in around €40-50 for the part (id have to check tomorrow)
    but if interested in a repair PM me and Ill let you know :)

    Thanks for the offer and the advice guys, got it sorted in the end. Well, it sorted itself out and is working fine. Bit of a scare though!
