Trouble with Minolta lens

Hi,

I got problems with my kit lens Minolta 28-80 D F3.5-5.6. When I turn on
my camera (Minolta Maxxum 5) camera cracks 5-10 seconds and set camera
to manual focus mode. I have tried to screw focusing element on lens
mount with screwdriver (very easy) - cracks go when focus have been
stopped at min focusing distance.

I can't go to the Minolta service center now because nearest center is
in 600 miles from my current location. Could anybody give me any
suggestion how to fix this trouble by myself? (In manual mode lens works
perfect)

Thanks,
V

 

I don't understand what you mean by "cracks"? Noise? what? It
sounds to me like the AF drive is pushing the the lens when it
reaches the end of the focus range (min.) and so it is perhaps
not detecting the end of travel (I don't know _how_ it detects
end of travel, but point 5 below may help in this regard).

1) Do you have (access to) another lens that you can try. And
vice-versa, another body on which to try the current lens? This
will help isolate whether the camera or lens is the cause.

2) Remove the batteries in the camera. Let sit overnight. Load
the batteries and see if the camera resets to the correct state.

3) After this event occurs, do you try to re-engage the AF by
depressing and releasing the AF/MF switch? What happens?

4) Remove the lens. Look at the back of the lens where the AF
drive connects to the lens. Adjust the focus of the lens (focus
ring) and make sure that the drive head spins each way, freely,
without much resistance.

5) Clean the contacts. Use a pencil eraser and clean the
electrical contacts of the lens interface to the camera and of
the camera to the lens. Be careful that the particles
(eraser/dirt) do not land in the camera or on lens parts (esp.
rear element).

Hope that helps, but if you cannot get it going with these steps,
then send it in for repair.

Cheers,
Alan

Yes, the camera makes noise when it reached min focus distance.

Yes, I have tried another lens. It doesn't produce this noise.

In MF lens works fine, when I switch back to AF noise happens again.

I have tried it. It spins fine.

Thanks, I'll try your suggestions.

 

Hello !

Sound like that the lens is not right attacht to the bayonet - Unmount
an remount the lens. Then check if the lens is mountet right, and turn
the camera on.
You can try to write a mail to the minolta support - here in germany
they awnser mailrequest good and fast.

What's about to go to a photo shop and test the lens and body against
running hardware ?

Good luck
