Você é um fotógrafo ávido? Você está tendo problemas com a retração da lente da câmera ou simplesmente quer saber mais sobre o problema? Então você está no lugar certo!
Este artigo discutirá o que fazer quando a lente da câmera não se retrair, incluindo todas as soluções possíveis.
O que significa que sua lente não irá retrair? Isso significa que a lente da sua câmera é estendida para fora do corpo da câmera e não vai retrair ou dobrar para dentro da câmera. Se a areia está presa em sua lente ou está dobrada devido a uma queda acidental, existem muitas soluções para cada problema, incluindo soprar ar comprimido, usar uma agulha, aspirar, alinhar o cano, substituir a bateria, trocar o cartão de memória e desmontar .
Tudo depende da causa. Este é um problema comum em todas as câmeras e pode ser tão simples quanto areia presa na lente ou tão complicado quanto um pedaço quebrado. Estamos aqui para ajudá-lo a identificar o problema seja ele qual for e corrigi-lo!
O que é uma lente retraída?
Uma lente se estende e se retrai na maioria das câmeras compactas. Isso se refere à lente estar em um estado operacional estendido e em um estado de retração de armazenamento. Normalmente, quando a câmera é ligada, a lente se estende e quando a câmera é desligada, ela se retrai. Isso difere em câmeras em que uma lente é destacável, mas todas têm mecânica semelhante. Em uma câmera digital com lente não removível, uma lente retraída geralmente resulta em um corpo de câmera plano.
Quando a lente é uma peça separada da câmera, ela é totalmente retraída em sua configuração de zoom mais baixa (por exemplo, uma lente de 25-300 mm seria totalmente retraída em 25 mm). Abaixo estão fotos de uma lente retraída e uma lente estendida. Este artigo discutirá o que fazer quando sua lente não se retrair, o que significa que ela permanece no estado estendido.

Como você retrai uma lente em uma câmera funcionando corretamente?
Sua lente pode não estar se retraindo simplesmente porque você não sabe como retraí-la. A maioria das câmeras digitais tem uma lente retrátil automaticamente. A lente se estende e se retrai conforme a alimentação é desligada ou ligada. Para retrair a lente quando a câmera não estiver em uso, a maioria das câmeras possui um botão de barril de lente retrátil que pode ser pressionado.
Outros exigem que você gire manualmente o anel de zoom na lente. Gire o anel de zoom para o “número de mm” mais baixo para retraí-lo totalmente. Seja como for, o guia da câmera o ajudará a descobrir como retrair a lente da câmera se estiver funcionando corretamente.

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.

Conclusão
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.
