L'objectif de l'appareil photo ne se rétracte pas :voici ce qu'il faut faire

Êtes-vous un photographe passionné? Avez-vous des problèmes avec la rétraction de l'objectif de votre appareil photo ou souhaitez-vous simplement en savoir plus sur le problème ? Alors vous êtes au bon endroit !

Cet article va discuter de ce qu'il faut faire lorsque l'objectif de votre appareil photo ne se rétracte pas, y compris toutes les solutions possibles.

Qu'est-ce que cela signifie que votre objectif ne se rétracte pas ? Cela signifie que l'objectif de votre appareil photo est éloigné du boîtier de l'appareil photo et ne se rétracte pas ou ne se replie pas dans l'appareil photo. Que du sable soit coincé dans votre objectif ou qu'il soit plié à la suite d'une chute accidentelle, il existe de nombreuses solutions à chaque problème, notamment souffler de l'air comprimé, utiliser une aiguille, passer l'aspirateur, aligner le barillet, remplacer la batterie, changer la carte mémoire et démonter .

Tout dépend de la cause. Il s'agit d'un problème courant dans tous les appareils photo et peut être aussi simple que du sable coincé dans l'objectif ou aussi compliqué qu'un morceau cassé. Nous sommes là pour vous aider à identifier le problème quel qu'il soit et à le résoudre !

Qu'est-ce qu'une lentille rétractée ?

Un objectif s'étend et se rétracte sur la plupart des appareils photo compacts. Cela fait référence au fait que la lentille est dans un état de fonctionnement étendu et dans un état de stockage de rétraction. En règle générale, lorsque l'appareil photo est allumé, l'objectif s'étend et lorsque l'appareil photo est éteint, il se rétracte. Cela diffère dans les appareils photo dans lesquels un objectif est amovible, mais tout a une mécanique similaire. Dans un appareil photo numérique avec un objectif non amovible, un objectif rétracté donne généralement un corps d'appareil photo plat.

Lorsque l'objectif est une pièce distincte de l'appareil photo, il est entièrement rétracté dans son réglage de zoom le plus bas (par exemple, un objectif de 25 à 300 mm serait entièrement rétracté à 25 mm). Vous trouverez ci-dessous des images d'une lentille rétractée et d'une lentille étendue. Cet article discutera de ce qu'il faut faire lorsque votre objectif ne se rétracte pas, ce qui signifie qu'il reste à l'état étendu.

Comment rétracter un objectif sur un appareil photo qui fonctionne correctement ?

Votre objectif peut ne pas se rétracter simplement parce que vous ne savez pas comment le rétracter. La plupart des appareils photo numériques ont un objectif automatiquement rétractable. The lens extends and retracts as the power is turned off or on. To retract the lens when the camera is not in use most cameras have a retractable lens barrel button that one can press.

Others require you to manually twist the zoom ring on the lens. Twist the zoom ring to the lowest “mm number” to retract it fully. Whatever way it may be, your camera guide will help you figure out how to retract your camera lens if it is properly working.

Example of a camera with a detachable lens:

Reasons your camera lens is stuck and how to fix it:

There are many reasons your lens could be stuck. This section will be discussing those reasons followed by ways to solve them.

1. Sand and Grit

This is exactly as it sounds; sand or grit may be stuck in the lens itself. This interferes with the lens extension mechanism. This is the mechanism that controls the way the lens extends and retracts. Putting your camera in a case could cause dirt to get trapped with the camera. Also, not using a case could get dirt stuck in your camera. So, whichever you choose, just keep your camera clean. There are a few ways we are going to explain how to clean the sand and grit out of your camera lens.

Sand can get caught in your lens barrel resulting in the lens not being able to retract:

Solutions:

Air

Do this by blowing compressed air into the gaps around your lens barrel. If you do not have access to an air compressor then blowing it with a hair dryer on cool can also help in this situation. One could also try their own breath if it comes down to it. You will just have to blow hard on your camera lens.

Piece of paper

If blowing air does not help consider using a thin piece of paper or sewing needle to remove the sand particles. Be aware this second method can damage your camera if you are not careful. One can go about this by taking a piece of paper and lightly moving it in the cracks of the lens barrel where the potential sand is. A sewing needle could cause more damage but may be more effective for finer particles.

Tapping

One could also repeatedly tap the rubber usb cover on a hard surface with the attempt to dislodge any sand particles. You could also hit the side of the camera with your palm. One could also try tapping around the lens barrel with a pen or pencil with the idea of dislodging any particles.

Vacuum cleaner

A vacuum cleaner could also be of assistance by sucking the sand or dirt out of the camera, although this approach is more of a last resort because it could lead to the most damage within your camera. There are many ways to dislodge sand and grit from your camera, just be careful not to break your camera further in the process!

2. Camera Has Been Dropped

That is right, if you drop your camera with the lens extended it could break the lens extension mechanism. This is best fixed by a repairman and not at home. But, if things have simply just shifted or bent they could possibly be put back into place.

Solutions:

Barrel guide pins

The lens barrel guide pins could have shifted from their slots, so you would try to put them back in place by straightening the lens. Do this by gently banging on the lens in attempt to straighten it. Listen for a click to indicate that the pins have been put back in place.

Align the barrel

The barrel itself could have been bent in the event of a drop. Fix this by gently forcing or banging the bent area back into place. If forcing it does not work try gently pulling, rotating, and twisting the lens barrel to align the barrel.

3. Something Blocking The Lens

The issue could be as simple as something is in front of your lens blocking it from extending. To solve this problem simply remove the object that is blocking the extension of your lens. If sand is the reason it is blocked read the section labeled “sand and grit”.

4. Camera Power and Equipment

Battery

The battery of your camera could have died with the lens extended. Plug in and charge your camera to solve this problem. You could also put in a fresh set of batteries and turn the camera on. Rechargeable batteries more than a year old can be worn out and not providing enough power to your camera. Replace them.

Memory card

One could also try removing and replacing the memory card. Sometimes it is a software issue and removing and replacing those items could reset the system and fix the problem.

AV cable

Your camera may also just need an extra boost of energy to power on that lens retraction. Try plugging in the AV cable to give it that extra boost.

5. If All Else Fails

If all the solutions above do not fix your camera and get that pesky lens to retract then you could try a little more radical measure- disassembling your camera. Disassembling your camera is simpler than you think and with a proper guide or video anyone can do it. One would do this to dislodge sand or to replace a bent/broken piece.

If you feel uncomfortable taking your camera apart then it is best to contact your local camera repairman. Finding a replacement lens is also another option if all else fails.

More tips for camera lens that is stuck

As stated in the section above, how you repair your camera depends on what the problem is. If sand is stuck in it, then clean it out. If your camera is dead, charge it. Many camera owners do not want to pay to have their camera repaired because it can often cost as much as the camera itself. That is why articles like this are here to help! If your camera is under warranty contact your local camera repair shop for more information.

Below are a few more things you can try.

Turn the camera off and on

The first thing someone should do when attempting to fix their camera is turning it off and on. If that does not work move onto the next steps to fixing it.

Factory reset

One could also try factory resetting the camera. Each camera has a different way to factory reset it, so look at your camera guide on how to do so.

Forcing an autofocus

Occasionally forcing an autofocus can fix the problem. Do this by turning on the camera and pressing the shutter button at the same time.

Conclusion

All in all, there are many reasons your camera lens could not be retracting. A lens that will not retract is a lens that is extended partially or fully away from the body of the camera. Thankfully, this article is here to help with this issue. With a detailed discussion about what can cause a failure of lens retraction and the solutions behind it. From sand/grit, dead batteries, and even dislocated guide pins there is a solution to each problem! The solutions range from turning the camera off and on to completely disassembling the camera.
