Lens rotates more than expected

Good afternoon

I have question about 85mm 1.8 USM in Canon. Once put on the camera, it is beautiful and works perfectly fine, but when I want to remove it, the lens do not line up with the dot on the camera (marked point) you can activate all around, almost a full circle.

Anyone had similar experience, and if so, you can share your experience and your opinion?

Have a great day.

There is a small post on the mount that acts as a rotation stop.  If that judgment is gone so the lens can continue to run beyond the point where alignment dots.

Here is a picture where I circled the judgment.  Your goal may miss this part.

  • Window 2 day using FRA more than expected recovery.

    Hello, can someone please help me understand why my 2 day recovery window uses a lot more space FRA than I expected.

    Here is some basic information.

    Oracle 11g R2

    Windows 2008R2

    The database size = 16.77 GB

    I have my FRA

    Newspaper archives = 10.5 GB (approximately 2-3GBs daily)

    Backupset = 1.63 GB (500MB per day)

    Control file = 16.3 MB

    Copy of image DB 13.7 GB

    Journal online = 30MB

    I use the Oracle out of the box back up strategy

    Run {}

    allocate channels oem_disk_backup device type of disk.

    retrieve the copy of the database with the tag "ORA_OEM_LEVEL_0".

    extra strength 1 cumulative backup copies = 1 to retrieve the copy with the tag database 'ORA_OEM_LEVEL_0 ';

    }

    FRA my height is 60 GB.

    I do not perform backups on tape (which RMAN knows)

    Everything is on disk.

    I expect at some point that Oracle will review files outside of my window of recovery to be recoverable, but I am struggling to figure out when.

    Now, if I put a window of recovery of 1 day (it's the current setting). It builds up to about 23 GB then it will start to have recoverable files. If I put a 2 day recovery window, it will consume all of 60GB and ends up falling. Why a 2 day recovery window is to consume as much space (more than double)?

    I know that everything is on the disk and maybe that's my problem. In my scenario when oracle would consider to be recoverable files?

    I thank very you much for your time.

    Hello again;

    on "oracle considers the files to be recovered.

    The only answer I have ever seen on this is when "Oracle feels the pressure of space", rather vague.

    Be careful when you use the window of recovery that you put it high enough to cover yourself.

    Im running ios 10.0.1 on my iphone 6 s and my photos told the 6 GB but only six have photo. I tried the fix for date, but which did not show anything to recently deleted or affected photos of ghosts.

    Hello there Brony1942,

    Looks like you don't have much in your Photos still shows settings app, you have much more space which should be used. I would like to start by forcing the Photos and the settings of applications to close:

    Force a nearby application on your iPhone, iPad or iPod touch

    Then restart your phone:

    Restart your iPhone, iPad or iPod touch

    If that does not get the storage to update and display correctly make a backup of your phone to iTunes and let us know:

  • Copy to the Clipboard, method (Table) copy an extra empty column more than expected

    Hello

    I use the copy to the Clipboard method for a Table, for example copy 4 rows with 3 columns. When I paste in Excel I get 4 rows with 3 columns and an additional column, which is empty, then the actual size is 4 x 4.

    Is it a mistake to Labview or can someone there explain to me why this is happening? Or better yet, how can I fix it?

    I've isolated the problem to an additional vi so that you can reproduce the error. Just let the vi run once and then paste the Clipboard to Microsoft Excel.

    Hey Vinod Dhaka

    with the dell recovery discs you would normally follow their instructions to reinstall vista

    put simply you never made a big enough partition

    Microsoft recommends for vista professional who was anyway too small 40gbs

    "HDD 40 GB at least 15 GB of available space (20 GB for the basic home edition"

    you have updates of programs etc to install

    and you say not the size of your hard drive, or how it is implemented

    use of your hard disk space correctly and reinstall vista or read this tutorial below to remove expand partitions

  • Windows 7 seems to take more disk space than expected on the C:\ drive

    Original title: size of windows 7 the disk

    I installed windows 7, 64 bit on my machine.

    I have made 3 partitions: C = 100 GB and the rest of the form 1 TB disk space divided in two other partitions. (those who have files it contains)

    Now, when I go to the COMPUTER, with windows (C) says that he has only 47 GB free which means windows takes more than 50 GB. But when I go on the content of this partition and see the size you of files... It shows only 12 GB, and there is no hidden inside folder.

    Can someone help me with this? Thank you

    Windows 7 uses about 8 to 10 GB of disk space.

    Click Start, type: advanced system settings

    Press enter on your keyboard

    Go to the System Protection tab

    Click Configure system restore

    Make sure that the system restore does not use too much disk space.

    Use the wheel to reduce the amount of disk space.

    In addition, the amount of RAM you have installed, it will take more disk space for paging, hibernation, and dump files.

  • Battery blackBerry Bold 9900 Smartphones worsens more than 50% after 2406 upgrade

    My battery life Bold 9900 worsened considerably after the recent OS 7.0 Bundle 2406 set to level. I had previously struggled to spend the day on a battery, but in general, I could do it for a day and business general use of electronic mail, of limited calls and not Web browsing. Now, after the recent 2406 upgrade, I get only about 50% as much battery life. In addition, the black box of the small Center with white rotating second hand is now a function that comes back regularly throughout the day, and I had to remove my battery to restart my BlackBerry much more often. I've since removed all applications, cut back on all the other battery draining features (screen brightness, wifi, Bluetooth, gps, etc), moved to 2G to extend my battery life. I was already unhappy with the bad battery BlackBerry Bold 9900 life, but after this last update 2406, it is unacceptable for a professional use when it only works for 1/2 day. I hope it's a question of battery RIM known for Bold 9900 that is processed quickly. Otherwise, I am one of the many who will have to move to a more acceptable solution for phone smart business in a perspective of battery life. Thank you.

    Well, I have implemented battery BlackBerry 9900 technical of economy in this forum, and to my surprise, he solved all much more than I expected. My last load battery Bold 9900 lasted 6 days/86 hours (compared to less than 1/2 day) during normal use of business and weekend for the phone calls, emails, texts and the bbm, exclusion using the internet or applications. I moved 2 G + 3 g to 2G only, off all the apps (especially GPS, Google sync and social networks), turned down the brightness of my screen and shorten the waiting time, calendar, disabled wifi and bluetooth, etc. Thanks for all the comments in the forum. They worked. Now I will be slowly adding some applications and using 3 G on the internet once again, and I will more closely control my battery drain in the future.

  • How can I get Firefox to use more than 12.5% of the capacity of my modem wireless?

    Only if you use Firefox, pages take forever to load. Use of my wireless router in looking, I found that it runs in general (with just Firefox, no other program running on the internet) to 0% or 0.0%, with few spikes up to 5%. Even when you try to view a video.

    When I download something, it could rise to more than 12.5%, for a bit, but I never saw that he hit even 50%.

    When I'm doing something which seems that it takes more ability to my router, Firefox instead takes a bit of my CPU, I'm guessing that there is a lot to ask where are the packets of data or something.

    I have no proxy, or restart Firefox update worked, nor has completely rebooted my computer. I adjusted my network connections down, then back to the top, and all that did was make it so that I can't watch youtube videos, which she usually takes me a few tries to load in a resolution that will not hurt my eyes, and it is with an add-on that makes it so that they are forced to play in HD!

    OK, it's alright with the ISP part - I thought, as had shown activity wireless adapter testing with IE more like what was expected.

    I've also updated the two FF (not something I want to do, as it rarely is compatible with my Add-ons update. My set up is fine, it works, why should I change to something that will not be?), and an update of the computer (which, Yes, I should do it more often. A final which will automatically but has been massive, however and literally broke my copy of FireFox. It was boring!).

    I still feel like it runs too low, but at least the videos loading and read without problem now-well, for the most part.

    They load, kick up an error for a few moments and then screen reload and then play correctly. I guess I can live with that.

  • Activation of Thunderbird requires more than TWO minutes after clicking on icon Thunderbird.

    PROBLEM: The Thunderbird program is slow to activate. When you click the Thunderbird icon, I expect Thunderbird Inbox screen to appear in a few seconds. However, after clicking on the Thunderbird icon, more than TWO minutes elapse before the Thunderbird screen appears. This problem existed for about a week. My OS is Ms 8.1. You can provide any help would be appreciated. Also, when this problem started, I received the following message "warning: this file is being processed.» Please wait until processing is complete, to pass messages. »

    Your anti virus (or attempt to Microsofts Defender grant) needs to be said is not to analyze the profile of Thunderbird folders, each time you open the program is my guess. The program cannot open files that are locked for scanning. As some of the files may be in the order of 4Gbv in size, it can take an AV program up to 10 minutes.

  • iPad backup restore take more than two days

    WWas of problems with the battery on my iPad Air life. taken at the Genius Bar at Apple Store. they reset and set up to restore a backup, what they did before.

When I go in the backup, it says still iPad is restoration. Should I stop & then restore again? Are they redo the apps that have already been restored?

    Thank you, Cheryl

    Hi cgibson,.

    Thank you for using communities Support from Apple.

    I see that you are going through a process of restoring iCloud on your iPad, and it takes longer than expected.  The speed to iCloud restoring has a couple of factors, including the speed of your wireless network.  For more information on why this process can take some time and how to follow the process, please see below:

    Restore my device from a backup to iCloud takes a long time

    Restoring a backup can take time because of the size of the backup or the speed of Wi - Fi network. For example, iCloud may take about 1 to 4 hours per gigabyte during a restore process.

    There are several steps that follow:

    • In iOS 8 or later, check the status of the transfer on your device under settings > iCloud > Backup. If the restore process is in progress, the backup setting is gray.
    • Make sure that your device is connected to the Internet with reliable WiFi.
    • Make sure that your device is plugged into a power outlet.
    • Check the Apple progress bar that is displayed during the transfer of a backup.

    If you need help, restore your device from a backup to iCloud

    Have a good.

  • WindowServer []: GPU Driver seems to be suspended (more than 5 continuous seconds of reluctance)

    Hello

    I have a huge problem with my iMac to year < 1 5K. It seams it is not capable of running tools. At least that is the statement that the Apple dealer gave me the excuse followed, I expect that Apple updated sound driver and hope that the problem will disappear.

    But one after the other. I bought this iMac I have a configuration with the best available (i7) CPU and 16 GB of RAM in April. When I asked if the least performing graphics card is sufficient to run application oll but games, they assured me that this is the case. Then all year there was seldom behavior with this mac, because after a while, he started to suspend for a period at the beginning a few seconds and after some time a little more until it becomes completely unusable because of the high frequency of gels. These gels has disappeared, especially when the focus of the application has been changed (cmd + tab), but come back more and more.

    The first thing I did, I even if this thing is broken and got a new logic board installed, but the ramains problem.

    After all, I discovered that the log is full of statements like:

    WindowServer []: GPU Driver seems to be suspended (more than 5 continuous seconds of reluctance)

    When the application is frozen. So I got the iMac to the dealer. Just today, they called me and told me that this problem is related to all THE tools of creation as Photoshop, but also of music like Ableton and same logic X programs! They told me I have to wait for Apple to arrive with a new driver of the logic board that hopefully solves the problem. I mean that literally, they confirmed that the iMac 5K is not able to run any creative Application at the present time for a longer while.

    My question is, what should people like me do, when the sole purpose of this computer was creative tools. Is there a program to switch to another machine like MacBook or Mac Pro or are the iMacs postum declared as not usable for creativity and buyers, and even less in the rain?

    Sorry, but my last post was so full of typos, I was really offset after the retail bank and need some time to get down. I'm sorry. This is a rewritten version, with most of the corrected errors:

They told me that I have to wait as Apple launches the new driver of logic board, which hopefully will solve the problem.

Is there a program to switch to another machine such as the MacBook Pro or Mac Pro or are the iMacs postum declared as not usable for creativity and buyers, and even less in the rain?
