Dear Carol484:

The autofocus mechanism in your camera and lens is very complicated and can get out of "calibration" causing AF problems. Of course there are external factors that can cause this as well (dust, moisture, shock, etc). In Africa these external factors may come more into play than usual.

Of course the first and obvious remedies to try includes such things as:

1. Cycling your AF/MF a couple of times (switch it back and
forth a few times to see if it helps)
2. Removing your lens from the camera body and cleaning the
metal contacts there (preferably with an electrical contact
cleaner, but an eraser will do in a pinch)
3. Performing a hard reset on your camera (Resetting the set-
tings to default, removing the batteries for a few minutes,
and then reinstalling them)

If none of these help, use your Manual Focus until you can have the lens sent into a Canon Service Center for calibration and possible repair. Good luck.


Sincerely,
HeavyDLB

Auto focus confirmation little green dot is blinking


Usually that means it cannot grab focus. That can occur for numerous reasons such as:
  • Subject does not have a defined contrast (all one shade of color).
  • Too close for the lens to work, each lens has its own limit on close focus.
More information from you will greatly help those that want to assist you.

Pictures didnt develop


Hi Steph Johnson,
Numerous things could be the issue. 1, dirty lens, clean the front and back element, 2. The camera focus is not working properly not focusing on the correct spot. So, are you manual focusing or auto focusing? If it is auto then there could be an issue with that. If your are manual focusing are you sure your diopter setting is correct for your eyes, if not then it may appear correct in the viewfinder, yet be off focus.

Do you have a way to check the lens on a DSLR? If so you can try that lens on the DSLR seeing if there is an error with the lens or if it is your film camera.

My tilt/shift lens isn't working with my Minolta Maxxum 400si - the aperture which is controlled through the lens won't communicate with the body, is there a way around this?


Is this an auto focus lens? Most shift lenses are manual focus. Also, because they shift, they can generally only be used on manual not he auto settings. If the contacts are not on the back of the lens then it will on communicate with the body

My Nikon N55 will not auto focus.


Depending on the type of interchangeable lens you have mounted on the camera, there may be a switch on the lens barrel for choosing between auto-focus or manual focus. The N55 also will not auto-focus with the newer Nikon AFS lenses such as those used with the Nikon D40 digital slr. Finally, there was a service bulletin on the N55 back in 2005. Nikon discovered a problem with the auto-focus and fixed it for free, but there may have been a time limit. Here is a link to more info about that:

Hope this helps : -)

Sorry, the mounts of Minolta manual focus lenses are different than their auto focus series. Sigma, Tokina and Tamron all make compatible zoom lenses to fit the Maxxum series cameras

Camera will not auto focus


Take the lens off and rotate the focus ring, it should turn very easily with little gear noise.Try a different AF Pentax lens that you know is good.
I'm sure the lens is binding, take the lens to a camera repair shop for an estimate cost to repair.

Lens will not zoom in or out


Brush off any lose dirt from both the lens and bayonet mount and the autofocus drive shaft . If you are still not getting camera to auto focus your lenses have an expert look at the body : this is not an expensive problem to repair on these Pentaxes either a small mechanical problem or the connection to the pc board is bad. In either case only the front of the camera has to be dismantled ( +- 1 hour of labour to do the whole job ).
