Afternoon One and All,
I have a bit a dust btwn the first and second elements on my Bigma. Looking for the service manual that would show the correct way to remove the outer glass so I can remove the dust and put it back together with out disturbing the rest of the elements. Sigma wants a minimum of $175 to clean it, which seems kind of expensive. They will not sell me the manual since I am not an authorized repair center; however, I am an A/V Tech, and am familiar with service manuals and schematic diagrams. Any help is greatly appreciated :bow
Thank you and have a good day :D
Jim...

    Hello,
    I wouldn't think removing just the outer element would misalign the remaining elements, but I could be wrong. Lets ( hopefully ) get a few more responses on this issue as well then. Thanks for your input :D
    Have a good day,

    Actually, depending on the lens, removing the front element "can" cause the lens to go out of alignment, and a scratch can cause a lens considerable permanent damage.

    A $900+ lens is not a good subject for practice, and the $175 is not too much for the assurance of quality work. If you can't justify that charge, the dust is probably not worth messing with.

    Hey Ziggy,
    Thanks for the info :D . Wasn't sure if that was the case. In the past, I have removed the screw ring holding down the front element of 3 or 4 different primes ( Contax ) and successfully removed dust, then screw the ring back in place with no trouble. Sounds like a different scenario here. Well what to do now ??? Thank you again for the advice :D
    Have a good evening,
    Jim...
