It sounds like the optics in the lens are no longer calibrated. It needs to be looked at by a professional.

SOURCE: Auto focus at full zoom not responding Nikon D80 with 18-200mm VR

Hi - I own this lens and it manually focuses at all focal lengths (hard to see at 18mm unless your subject is extremly close). You may need to get the lens checked. BTW - Mine was set as follows when I checked for you:

  • D80 was "on"
  • M/A
  • VR = Off
  • Normal (not Active)
Hope this helps!

SOURCE: Auto focusing not working, Lenses don't rotate at all

i did some research on this problem and one of the things mentioned was that there may be a firmware update to address an autofocus problem with this camera.
Here is a page that may help you get the firmware update.

also another thing you may want to do to alleviate this problem is to reset your camera settings to the default setting and try it.

Good Luck

This means that the communication with the Quantarey lens is not the right one.

You can try in cleaning the lens contacts and the camera contacts with a pencil eraser or a white erase (flip down the camera so no particles get inside the mirror box).

If still you are having problems, then that means the Quantarey lens is defective, and either needs to be service to be repaired, or you will need to get another zoom lens.

Best regards,

I had the same problem with my camera. I unscrewed the casing and removed the front jacket, I then eased the lens back into position. It will make a firm click when the gears reengage. Powered the camera on and manipulated the zoom. then powered it down and the lens retracted.

The lens does not focus manually or automatically.


Hi.
I have a lot of experiencie repairing Sigma lens.
In this zoom 150-500, the problem is located at the focus mechanism. This is a rear-focus lens so the focus mechanism is close to the bayonet.
It is not very hard to repair, but is better if you send to a Sigma Service Station.
Normally the mechanism is stuck due to a fall or strong punch.

There are adapters available to fit the old Minolta manual-focus lenses on Sony alpha-series dSLRs as well as Sony NEX-series interchangeable lens cameras. The lenses obviously will not autofocus and, depending on the lens and camera body, you may lose some or all exposure metering capability.

My HVR-V1U has a focus problem. In manual focus mode, when I zoomed in and focus and then zoom out, it is not in focus anymore. But if I leave the camera in auto-focus it is fine. I don't see a way...


That's the backfocus problem. Take your camera to a Sony service.
If the lenses are ok, they will do an adjustment. If the lenses are defective, they will
replace the lenses, but that costs much.

Can you use the twist-barrell zoom lens on a Sony DSLR camera (or any DSLR) when the camera is set to auto-focus? I've been told that this damages the gears in the lens if you do. Thanks for your help.


You can zoom completely independent of the focus.

Some lenses immediately override the autofocus when it senses you turning the manual focus ring. Other lenses don't, and you can damage the lens by forcing it. It depends on the lens, so you'll have to consult the documentation for the specific lens.

Why are my pictures blurry when focus is all the way out, and focused when all the way zoomed in? this is also visually obvious on the lCD screen. zoomed out( out of focus)..zoomed in( in focus).


your camera's lense is clear? try clean it with suitable cleaner for lense. If still not working, check your user manual for setting

Hi I bought a pro-spec 70-210 lens for my Sony Alpha. When you go to zoom out it doesn't twist. You can pull it straight out...Is this how it should work? The rest of my lenses all twist out


Yes. It's a push pull zoom action.

One touch zooms as used on 35mm film SLRs used to have the same mechanism, the zoom ring twisted as well to achieve focus but now that most lenses are autofocus that's unnecessary. So you have a lens which just retains the push-pull, a far more natural action in my opinion and usually faster than a rotating zoom. Once you get used to it I think that you'll prefer it.

By contrast, most modern zooms have what was considered in 35mm terms to be an old-fashioned twin touch zoom: one ring was turned to zoom the lens and another was turned to focus it. This sometimes meant that after zooming you had to refocus; your push pull zoom will likely have a more technically demanding constant focus zoom action, there will be an additional manual focus control as well, but it's very much a minor secondary control used only when your AF has broken or is switched off.

I hope that my reply has been of use to you, please return the favour by rating my answer.

Sounds like there is a misalignment internally. This will probably need to be repaired at a shop.
