I'd guess, from when this lens was introduced, that it is out of warranty? My web search did not turn up any reference to what you have described. Whether or not in warranty, I'd suggest starting by contacting sigmaphoto.com to see if they have any suggestions. FWIW, I have the (newer version) 50-500 OS USM on a 7D and am very impressed with it (first non-Canon lens I've bought).

Lens will only partially come out - a few mm - when powered up. It then retracts.


The lens is retracting because there is something preventing it from fully extending. It is a safety mechanism built into all digital compact cameras to be sure the lens doesn't force itself and break. Once it encounters resistance, it will retract.
Make sure there is no debris between the lens rings and try again. If the problem doesn't go away, you will likely need to take your camera in to be repaired.

I have a sony cyber t70 camera and have an error code E:61:00 come up on screen and i cannot take a pictue please help me .. what solution can i find for this.. venkatesh


Sony claims that the E:61:00 error means "Difficult to adjust focus Inspect the lens block focus reset sensor". In my experience this means that the gears that extend and retract the lens are somehow jammed. This could easily happen if you hit something with the camera with your lens in extended (working) position.
You should try to:
- power off the camera
- place your thumb on the back of the camera and the fingers a few centimeters from the closed lens
- power on the camera, and with your fingers stop the movement of the lens forcing not to fully extend
- when the lens retracts or stops and then continues to extend, let it go

sometimes this would resolve the issue.

wich has similar trick for a different model from sony, but the error is the same.
Be careful not to force the lens too hard or you may worsen the issue.
Let me know if this helped, good luck

EasyShare Z885 Digital Camera: unable to power up camera. lens remains fully exte...


If the lens makes a partial movement when you attempt to power up, it is probably dirt/sand that has jammed up your lens in the extended position. First use a vacuum to remove dirt between the lens gap. Next, be very careful, but when you power up, as the lens tries to retract apply a little force to help the lens, listen for a click that indicates that the lens barrel guide pins may have reseated in their guide slots. If you hear this click, immediately stop and try the camera

Turn camera on, lens goes in and out then camera shuts off


You may try resetting the Camera to the original factory settings.
If the issue persists then service will be required.

Lens not extending


You have a lens problem. Sure it can be fixed but be sure to get an estimate first.

Lens error


This seems to happen when something (water, sand, dust) gets trapped in the lens mechanism. Has the camera been somewhere filthy before?

The recommended methods include taping on the bottom of the camera, rapping it on a table, and pressing hard on the lens. If the lens moves when you turn the camera on, try keeping your hand on it so that it's forced back into the camera body. A can of compressed air squirted around the lens is also a possible fix... but be super careful with that stuff, a good hard blow of breath might be safer.

I'm not recommending that you do crazy stuff to your camera, but if you're careful you may be able to get it working again without having to get it serviced.

Lens error, restart camera


Lens error is usually caused by mechanical faults concerning lens assembly. The lens cannot extend or retract fully, the error is detected and lens error is returned.
Sometimes this can be fixed playing with the lens during extraction or retraction to help the lens asset getting back to normal.
More often the camera lens must be disassembled and re-assembled by a technician to fix the problem.

Lens does not move manually


You should not try to manually retract lens because lens has few gears in loading mechanism that can be broke if you put some force in try to rotate on lens.

Try removing your memory card. I had the same problem and this worked. You might need a new card. Good luck.

The camera says please turn camera off and then on again every time i turn it on I dropped my camera and now when I turn it on the lens goes back and forth and the display reads "Please turn camera off...


Hi,
I too have the sam problem but was able to solve it. I called the 1-800-number and was told that this is a very common issue or this camera. They told me to tap the lens when it was extended on a cloth or towel so not to damage it. The point was that there is often a piece of dirt or sand preventing the lens from retracting properly. Guess what, a single grain of sand came out when I tapped the lens and the camera worked perfectly ever since. I looked in the camera case since I keep the camera in it all the time and there were a few grains of sand that had somehow gotten into the lens!

I hope this can help someone else out.

Thanks.
