Normally, these lenses do not 'unscrew'. When you push the red button, it releases the lens catch and then you rotate the lens a short ways counterclockwise, then gently pull forward on the lens while holding the body of the camera and the two units separate. It is possible you have gotten some dirt into the lens latching mechanism. Try returning the lens to the locked position, press the red button, rotate the lens to where it stops and then returning the lens to the locked position and repeat several times if the lens does not lift out when you hit the movement stop. This may allow you to get past the dirt. Otherwise, take it to a camera shop, particularly if the camera is still under Canon warranty.

Remove the lens from the camera, set MF on the lens, try gently to free it by hand. If this works, clean the contacts on the lens and camera body - if not, it needs repair.

How to retract a stuck digital camera lens


If you have ever had the problem where your digital camera lens is in the out position and won't pop back in. This happens sometimes if the gear which retracts the lens gets stuck. I can't guarantee that this will work for all cases. If the gear is stripped or there is a more serious problem it may not work.

What you want to do is to tap sternly on the camera body. Don't bang it against something hard or the body may crack. Just give it a good wrap with the flat of your hand. I have used this technique a few times to unstick stuck lenses.

Can we repair/replace the lcd of old film cameras? I have an old pentax sfx camera and its lcd does not work.


I just checked my SF-1, and the mirror will go through four cycles while trying to load the film. You should be able to hear the mirror go up and down when you open the back and close it, then turn the camera on. I cannot get my SF-1 to keep the mirror up. Check to see if you have the mode set to bulb, and that the shutter release isn't stuck down - that will keep the mirror up until you release the shutter button or turn the camera off.

Also look carefully inside the lens mount on the side nearest the red dot. at the horizontal spot there is an internal button. It should be at the bottom of the track it runs in, about 1/3 of the way from the screw below the red dot to the lens release button. That moves up when the mirror goes up, and down when it comes down. If it is in the up position, you could perhaps try to gently move it downwards. It definitely moves up and down with the mirror on my SF-1.

How do you remove the lens if it placed on upside down?


There is no mechanical way of placing the lens on the camera upside down. There is only one way the lens will fit into the body and it takes about 1/8 turn to lock it in place. There should be no effort to installing the lens on the camera. To remove a locked lens make sure the camera is turned off hold the camera in your right hand close to your body and with your palm up. You will now be looking at the left side of the camera, there is a D shaped button just behind the lens mount. Wrap your hand around the lens so your thumb is positioned right at this button. Push the button in with the end of your thumb as you gently turn the lens away from your body. It will detach in 1/8th turn and come away from the camera. To reinstall the lens line up the dots could be white or red set the lens into the camera body and turn the lens gently clockwise and you will hear a click. It takes less effort to do this going on and coming off then it does to open a Peanut Butter jar that has already been opened once.

System Error (Zoom)


Hello

The problem is that the lens has become stuck in the barrel. There are some DIY solutions you could try, but the probability is that you will have to get it fixed by a professional.

Use these at own risk as it may further damage the camera.

Firstly , try connecting your ac adapter or usb cable.

Try holding the shutter button while switching on the camera.

Look at the lens , and if some of the lens 'circles' is misaligned or not concentric then try wiggling it (while holding camera lens down).

Try gently pushing or pulling the lens when it extends but this is risky as it may cause the lens barrel to slip out of its guidance system.

Another way to do this is to place the camera lens down on a hard surface and then power it up. Be sure to use a soft cloth or something similar as to not scratch your lens or casing. Let the lens push the camera up and down a few times and sometimes the little resistance provided by the camera is enough to get things going again.

Try hitting your camera near the lens on the body with the soft tissue on the palm of your hand.

Other than that , I would take the camera to a repair center for a evaluation to see if it would cost more to repair than to replace the camera.

If it is still under warranty I would suggest you take it in before trying any of these steps and remove any off-brand batteries or accessories as some stores are really fussy about warranty repairs on camera's with non-brand accessories.

Hope the advise is useful. please do not hesitate to let me know if you need any further assistance.

Regards
Andrea

Lens wont go in


I had the same problem, my workaround was:
1. turn on the camera, you will hear some beeping as the lens tries to raise from the body of the camera
2. wait until the camera turns off
3. pull the lens gently until you hear a 'click'
4. turn on the camera again, it will work normally (hopefully)

Another interesting thing, you can switch on the camera in "play mode" only, by holding down the play button on the back while pressing the power button. In that way, the lens will not raise and you can copy the images.

I have a Hasselblad 500c/m with the lens stuck on the body and I not turn the shutter knob. Help!


Get the back off the camera, make sure you can see inside the camera and locate a chrome screw in the middle below the lens.
Turn it right to align the locater slot of lens and body. Be very careful and do not use to much force. If you turn it enougn you can use the release button an unscrew the lens by turning it anti-clockwise.
