Macro lens EOS T3i not turn or focus

• EOS T3i - Autofocus problem

  Hi gang... I have an intermittent problem with an EOS T3i I bought for my wife.

  It was a purchase of kit that came with the 18-55 mm IS II lens.

  It seems that the autofocus function works imtermittently on my camera. I still have 2 months left on the warranty, but I want to run this by the group.

  At startup, the unit works very well. The autofocuses of stepper motor, the camera's going to break a few (or more) pictures. I'll hear the engine step by step to do its thing, auto focus points viewfinder shows and illuminate. Confirmaiton focus light begins to blink. The camera will make the two beep. the camera will take the picture.  Now when things go wrong, they go really wrong for this device.

  If I change a scene where the camera will have to move the lens and the automatic re-development. Engine step th does not light, auto focus points viewfinder will not not turn on and the right focus confirmation light will blink. If I press the shutter button, nothing happens. I have no beep.

  I called Canon support and they suggested a low level format. I did it but the problem persists.

  just need conformation that it's not normal behavior and I was wondering if anyone else had this type of problem. Thank you very much! :

  OK you need start the normal process of elimination.

  The lens works on another camera?

  The camera works with a different lens?

  The contacts between the lens and the camera are clean? Try denatured alcohol and a q-tip.

  You have already set the camera to the factory settings? It is not the memory card, BTW. The unit should work if she has a card in it or not.

  If these simple things have no success, a repair shop is probably expected.

• Help me with football at night on an Eos T3i

  I need help for the best shots of my Cannon Eos T3i night football games. Any suggestions?

  I'm going to assume that you have a photography course & don't really understand the basics of opening & shutter speeds. Your 70-300 is f5.6 WIDE OPEN with 300 mm zoom (it will become a fine f5.6 lens before reaching the 300 mm & maybe even before hitting 150 mm).

  Lens f stops relate to the amount of light, the lens CAN let in and dictate at what shutter speed is needed for ISO selected produce acceptable exposure. Because frost action requires faster shutter speeds, we will talk about the need to use 1/500 sec as the slowest acceptable speed for your night time football. NOW, we are talking about the DIRECT relationship between the shutter speed & opening. These settings produce the same exposure

  at f 2.8 shutter speed must be 1/500, but if the lens can open only at f4.0

  to f 4.0 (a full stop "slower" than f 2.8) you MUST lower the shutter speed to 1/250 second, but YOUR goal is a goal of f 5.6 (2 stops 'slower' than the f 2.8 lens)

  at f 5.6 you must slow down the shutter speed at 1/125 second, for the same amount of light for a correct exposure.

  BECAUSE 1/125 will freeze action your ONLY option is to increase the ISO, which introduces noise once it passes a certain point (which varies according to the age camera & original price point in a range of manufacturers.

  Again, there is a DIRECT relationship with ISO settings so let's start with the numbers to STOP FULL using ISO 100 as the basis. The numbering system is 100, 200, 400, 800, 1600, 3200, 6400, 12800 etc..

  IF you were to use your f 5.6 lens & the setting defined above, where the f 2.8 @ 1/500 has worked to say 800 ISO, a shooting game in the night, you need to bump the ISO to 1600 to turn the lens f 4.0-1/500 or all the way up to 3200 to shoot your objective f5.6 at 1/500

  All this is DONE, but there is another potential problem. Increase the ISO does not help the AF somehow. The AF will struggle to f 5.6 in the dark compared to how well a f 2.8 lens will allow it to work. Another factor is a combination of how the AF works in the lens. More expensive cameras have more money spent on improving the AF components & then make more expensive lenses. The will IS 70-300 L AF faster that the 70-300 regular IS who's going to move more quickly than the cheapest of the 70-300.

• Macro lens for Nex - 3n

  Hello world. I'm new in the world of photography, and I don't know that much about the specifics of the cameras and lenses. I have a Sony Nex - 3n and I want to buy a macro lens to use with it. I'm confused about what will be and cannot be inserted. If someone could help me it would be greatly appreciated I don't want to spend a lot of money only to find out the lens does not fit.

  With the help of the SAL - 30 M 28 will require the use of THE-EA3 or LA-EA1 lens mount adapter because this lens is a lens mount. The SALT-30 M 35 is a macro E mount lens that does not require the use of an adapter when it is attached to the NEX - 3N.

• Support for profile lens corrections are not not in Lightroom 3.2

  I installed the Lightroom 3.2 update, which includes the list of support for the 'Canon EF 50mm f/1.8 II' lens.  I pulled a number of pictures with this lens (using a Canon T1i) and load them into Lightroom.  In the metadata for the photos, the lens was called "EF50mm f/1.8 II.

  Within the "Lens Corrections" section of Lightroom, the option 'Auto' reports "Could not find a profile matching automatically."  I tried manually to the list of Canon lenses, and it is not on the list.

  In the folder
  / Library/Application Support/Adobe/CameraRaw/LensProfiles/1.0/Canon/
  I see a file corresponding to this objective
  Canon EOS 5 d Mark II (Canon EF 50mm f1.8 II) - RAW.lcp
  but it is not with only one specific body.
  I tried to manually install the update to Camera Raw 6.2, but he noted "update is not applicable."  Given the above file, I suspect that it was already installed.
  In the release notes, which entered the Canon EF 50 mm f/1.8 II lens, it does not mention that the support was limited to only a certain camera body.  Could someone help me please?  Thank you!

• MacBook Air 11 '' does not turn on or charge

  So here's my problem, I was using the macbook and I decided to close it and then fell asleep. On the next day, I opened it and try to use it, but he never responded. I thought that the battery is dead so I plugged in the charger and discover that the light never went. I was scared so I watched some videos about it and found that I just need to disconnect the battery, turn on without the battery but the charger plugged in, and close it down and put the battery, but who did not work at all. I also discovered that the charger light would come if I just used the charger on another macbook, any ideas on what to do?

• iPad IOS 10 - AutoCorrect keyboard does not turn off?

  I don't know if it is a problem of IOS 10 or if it is a question of the iPad. One of the first things I do when I get a new device is turn off easily. I hate to correct automatically, but it seems not turning off itself. I was typing a message to a friend of mine and to instead keep the word I typed (Pervy) it replaces (Percy).

  I just upgraded to IOS 10 and checked to see if the AutoCorrect has been disabled or if she has it on again. Even with typing this message, it keeps replacing words on me with words that I don't type and are not what they should be. It is not a question of spelling either, so I don't know what to do to fix, but it's very annoying.

  Hello. You may also need to disable predictive. If you are using a physical keyboard, there are different settings for it. They appear only when it is connected.

• Watch will not turn on or charge

  Two days ago, I bought my watch and it worked perfectly. I left to come from overseas and I couldn't load it while on the plan so it is dead. When I'm here I plugged it in and now it is not turn on or charge. What should I do?

  Hello

  Try restarting your watch force: hold down the side button and the digital Crown for about 10 seconds, until you see the logo.

  If this does not help, then try to charge your watch for about 2 hours, making sure that you follow the instructions from here:

  • Check your battery and load your Apple Watch - Apple Support

  After this period, if it has not already restarted automatically, remove it from the charger and:

  • Try restarting it (by pressing the side button until you see the Apple logo).
  • If necessary, then try force it restarts again.

  It was AC off recently?

• With this update my computer not turn off. Clears the screen, but this is all about.

  This computer is the new 12-inch mac that came out this spring.when I've updated about a month ago, it would not turn off. I got tired of hold down the b power button to turn it off. I returned it for a back earlier upward. It automatically updated again and here I am in the same disorder. I think I'll just close the lid and stop worrying in this regard.

  Stop your Mac. Use the power button if you wish. Now start with the SHIFT key is pressed. This will start in Safe Mode, with all extensions turned off. Safe mode is slow to start, so give it time, it checks a lot of staff. If it works fine in Safe Mode, restart normally. If it works now, you are finished.

  If the problem comes back after a reboot, you have an extension conflict. Disable all extensions via system preferences. To isolate which extension is at fault, turn on an extension at the same time, restart in the meantime, until you find bad.

• 9.3.4 iOS alert tone calendar do not turn off

  Since upgrading my iPhone 5 to 9.3.4, I can not turn off the sound alarm for a calendar event.

  I have a Gmail calendar sync on my phone and all my calendar notifications are set as follows:

  Show in Notification Center > WE

  Sounds > None (alert sounds and vibrations are set to None)

  The app icon badge > WE

  Display the lock screen > WE

  However, the reminder time for a calendar event, I get an alert of the lock screen AND a "rope" carillon. I also tried to disable all notifications of reminders, but nothing is done, there is simply no way to activate sound alerts in the calendar. It wasn't the behavior of calendar on 9.3.3. Am I missing something?

  Another thing, that I discovered after the upgrade is that the captions under the buttons on the call screen are now highlighted. Is it because of the upgrade or some other setting?

  Thanks in advance for all the help and advice.

  Hi John,.

  Thank you for using communities Support from Apple. I know have a problem with notifications, it is not what you expect. If I understand correctly, you get a sound notification schedule even if this setting is disabled. Looks like you have tried to adjust some parameters already, so here's what I suggest for this problem:

  1 first, turn off the Notifications options for the calendar, and then restart your device under the tap down and starting process is important to keep the iOS software works correctly. Select the appropriate Notifications options and test this new:

  Restart your iPhone, iPad or iPod touch

  2. If you still experience the same behavior, I suggest to backup your personal data and then reset all the settings in settings > general > reset your device. This resets all settings on your device such as Notifications, which will have to be installed again after testing your problem of Schedule again.
