    Advice on 70-200

    by Busiboy » Fri Aug 12, 2016 1:59 pm

    Hi all,

    Long time no post.

    Things have been rough with kids but getting better and getting more chances to pick up the camera.

    A long time ago there was a incident with my 70-200mm it rolled off a table and dropped onto the front element end of the lens with the cap on, Since then however photos appear very out of focus.

    I tried from memory to adjust the focus however I believe I get different reults and different focal lengths.

    Is this a lost cause or can this be economically fixed?

    If dead I am thinking the Sigma 70-200 would be a good addition as the eldest is starting to play sports.

    Any comments welcome. Hope you are all well.

    Can it get sharp focus manually with magnified live view?

    Might determine if the element stacks can still achieve good focus, or if the AF mechanism is out of kilter.
    Only thing I can think of outside of someone pulling it apart.

    Hmmmm


    I started playing last night and I went through all the focus adjustments by 5 (-20 to +20) and there was no change in the image.

    I took it back to zero, wriggled the manual focus, hit the shutter and bang, snapped on sharp.

    I'm confused. :grrpsycho:

    Might've had an element group knocked crooked and bound up out of position and the manual input has been enough extra torque to loosen things up. Fingers crossed it stays happy for you!
