II + Zeiss 85mm serious Otus 1DX underexpose problem

Out of curiosity, decided to try my Otus 85 mm (used on the Canon 5dsr) on the 1dx2 and for some reason any metering system started going nuts. Tried measuring evaluative full and metering - same thing. Instead of 1250 to 1600 ISO get 250 ISO. Tried another lens (Canon 85 f/1.2 L II) - everything is good: ISO 1250. All corrections are disabled in the settings of the camera. Looks like a bug (or a feature ?)

  • Profile FE Zeiss 85mm f/1.8 for Lr5 mounts lenses?

    Hello

    I recently bought a Zeiss mounts 85 mm f/1.8 lens FE that I intend to use on a Sony A7II body.

    I did not know that: -.

    (a) the lens has quite bad code pin-cushion distortion, and

    (b) may not be corrected in camera.

    I see people saying, 'just OK in the post. But I also see that only Lr6 has a profile built for this purpose.

    I have Lr5.

    There is no way to download the profile to use in the Lr5? I really need to ditch Lr5 just for that?

    I downloaded and installed what is called "Lens profile Downloader" but he has a very short list of profiles - no frames.

    I don't know if I'm competent to create my own profile.

    Any suggestions or advice welcome!

    Best wishes

    Hi travvie,.

    From the 85 mm f/1.8 Zeiss mounts Lens profile is only compatible with Lightroom 6.1.1 or LR CC 2015.1

  • Satellite L300 - boring loading problems

    Hello world.

    I've got my Satellite L300 nice for about 23 months now, and I absolutely love it.
    There is just one problem: my PC is not loading properly. There are always about a 1/50
    lucky, I have to play with the inputs and output for all 5-10 minutes each
    I plug it in time. I had this problem before (about two months ago) where I sent it
    Back to the store and they fixed. I was able to pick up there is still almost a month
    and everything worked properly again.

    It's really, really frustrating and I hope there is a solution simple sorta.
    Anyone who is familiar with this problem and to know what exactly is the problem?

    Thank you in advance.

    This kind of technical problems, there is no simple solution.
    If you have a serious issue with load problem, it is probably related to electronic power supply and it must be checked by authorized personnel only.

    Tell me but honestly: what can you fix these problems?

  • Tecra A11 & Express Port Replicator II - USB problems

    Hello

    I'm having a problem with a port replicator that I simple couldn't have resolved for months. I'll try to explain this as best I can.

    We have a Tecra A11, which seems to work fine running on Windows 7 Professional. When the Tecra A11 is pluged in an Express Port Replicator 2, not USB ports in the port replicator's work at all. Very good cell phone fees and the LAN switches on the replicator fine, but the USB ports simly does not work under any circumstances. It would also be interesting to note that the green light next to the "eject" button lights never really.

    I downloaded and installed the latest series driver for Windows 7 from the Toshiba support page which has no effect. We had 2 replacements for Toshiba because they also agreed that the previous, we had were not woring correctly, but this obviously was not the case because we still have the same problem with our 3rd unit. The Tecra A11 was sent back to Toshiba with case notes clearly describing the question, and he was sent to us "no fault found".

    Unfortunately, we don't have any other laptops to test on the port replicator. but I'm seriously suspect that the problem lies in the laptop, rather than the port replicator. For any idea or suggestion will be greatly appreciated.

    Kind regards

    Steve.

    Hello

    According to your message, you are not sure if the problem is related to the defective laptop Tecra or express port replicator.
    Hmm theoretically the problem might be related to defective express port replicator or Tecra.

    If found some information on the USB ports and the repliators port:

    + Make sure that the element of Legacy USB in the BIOS emulation is set to "Enabled". This feature only works for the keyboard and mouse. Also note that the keyboard and mouse must be connected before you start the computer. A USB mouse, keyboard or the floppy drive connected to the Port Replicator via any other connection that a hub of the first level, will not work until the operating system has started. +

    I also recommend to check the version of the BIOS; If the most recent BIOS is available, then you need to update this

  • Q5 after problem blackBerry problem!

    Hello

    I installed the new OS update last night after having saved then wipe my phone to make room for her. I restored my backup to the phone when it was updated, but it was not to restore all my brackets back because now not enough room on the device after the new update (my device storage was already nearly full).

    So now that the phone is so full its comes crashing and even custom make anything, it's got worse during the night, now all it will let me do is turn it power or go to settings, something I click on crashes and closes before its even open correctly. I guess that this is due to my serious "complete storage device" problem, but the problem is I cant get onto my media to actually delete things because it crashes just so clicked! I tried to take my files through my laptop (plug my phone in it) I normally do and was about to remove all my multimedia items in the folder wile phones it was connected via a USB cable. But now my laptop does not even recognize my phone. I spent about 5 hours so far tried to connect to Link of BB, BB Blend, etc, but my files to phones are not still appear in my 'work '. He keeps trying to download the drivers, then explains his failure. It also keeps saying "error mounting of volumes". I have fidded with settings by ensuring that it is able to connect to devices etc. It was connected to my laptop yesterday, whats happened? I can't even use my phone until accessible ive somehow peripheral storage to remove everything! HELPPP

    After hours have disconnected and reconnected my phone to the USB cable suddenly somehow connected and I managed to do the sorting now.

  • PC Tablet tx2000 - display and wireless problems

    Hey people. I have a HP tx2000 tablet PC laptop with a year of purchase warranty - which expired last month, and now two serious and potentially debilitating problems encountered. I spent about four or five hours with the Livechat nice people, who were on the whole patient and temporarily managed to fix one of the questions.

    (1) the wireless device may not be detected - wireless laptop card is not read. It is a big downer for me because I'm using wireless exclusively at home and work and I really want to shell out money for a smart card to replace the technology on a laptop that is 1 year and 1 month. The first thing I tried was re - install Vista. The wireless adapter has been detected and worked just dandy until as soon as I restarted the computer. Then he disappeared from the Device Manager list. I have re-installed twice and it's the same thing. LiveChat directed me to a new BIOS to install, so I installed that, too. It's the same thing. Then Livechat instructed me to delete the program HP Wireless Assistant and bingo! The wireless worked very well and through several reboots. For a day and a half. Now, it is not found yet.

    (2) when the laptop from sleep or hibernation, the display is not 'wake up' again. The fan will be UM, the LED flashes, but display refuses to wake up. The only way to solve this problem is to restart the computer. This also happens / every time / I switch on the computer itself. The display will be activated, no post screen, no beep system seconds later. The only solution is to hold the power slider until the system is a closed hard down, and then click again to turn the computer back on. This usually works, but sometimes it takes 2 or 3 tent.

    The Livechat was to update my video drivers, and they sent me a nice handy nvidia update.  To restart the installation, the computer performed normally, but as soon as I rebooted again (after the conclusion of the session of Livechat marathon at 5 in the morning) the white screen problem has occurred. I also tried to install the latest drivers from the nvidia site (which have been updated from those HP gave me), without result.

    I've read about these two problems on various boards of the internet; Wireless outage seems to be something very common with pavilions and the chipset, even if it is fairly unique in that reinstall allows the system to 'find' immediately and it works very well, and Livechat HP gave me a working solution where the wireless ran for a day and a half and ten or twelve of the low power/ups power. The problem with the monitor, however, seems very widespread and is frustrating in the extreme to me and many others. Much the assumption it implies the tablet technology. My previous laptop was a Dell Inspiron with a large, 2 "hole diameter engraved on the screen, and Support from Dell wouldn't even talk to me even if they had a unique way of extension of the guarantee for what is a major problem of manufacturing. Nevermind, I have below the 3-year warranty, and they would just me shuttle for a salary-service as soon as I gave them my tags. I lost all faith in Dell products accordingly. HP, on the other hand, was very polite by Livechat, and I read some of these forums... It seems that if people know what they are doing here. I don't want to throw more money on another laptop, and the Tablet functions are the bomb. I want just a working laptop.

    See you soon,.

    Hello!

    I got a free replacement of Hewlett-Packard after 30 or two hours and two months of work with HP, as follows:

    (1) contacting a case manager (call HP, o askt be xferred to the records management) and pointing out that:

    (A) my laptop (as well as many others here and elsewhere) suffers from symptoms described in the limited warranty Service extension (http://support.hp.com/us-en/document/c01087277 and HP can agree with that

    (B) the only reason for which it is not covered by the LWSE that the above is that my system is not listed as an attack (it is yours or thousands of others)

    (2) However, 2 months out of warranty case manager first offered a half - off repair (what tech support told me was $428), then again a repair for $90.

    (3) I refused both offers, because it is - of course - a manufacturing defect that affects much more than just a handful of systems. HP is completely ignoring people and hoping it will go away. I got ahold of all the e-mail addresses of single senior partner/CEO/worker I could and started FREE shipping asked to fix my laptop as I MERIT because it is DEFECTIVE.

    (4) Finally, one of the e-mails came to the attention of the Executive customer relations. 15 minutes to speak to a representative, he decides to give me a free repair. All there was to it. The mail box arrived at my door two days later.

    Yes, good luck for the rest of you... I stand testament to the fact that HP gave a free repair to an owner of a machine of series tx, suffering from the failure of GPU Nvidia (missing sporatically wireless are the first and the most common symptom of this). You can get your machine fixed and must never pay for it. Components of a laptop should last more than 13 months! NVIDIA and HP as well acknowledge the failures, but not released any information on what parts have been affected. It is to you, noble drive, to make a pretty big stink to get HP to fix your investment.

    And don't forget... Do not buy HP again!

    See you soon!

  • When I open a new tab, the address box filled with an unwanted, unused address, it don't go there, I don't want filled automatically, how to fix?

    Whenever I open a new tab in Firefox, this address is the address bar: chrome://quick_start/content/index.html. Now, I have nothing against it, but I can't seem to get rid of it. I went to my settings and Add ons and it does not work. Tried to see if I could find somewhere in my internet settings on my computer control panel. I just had someone delete some serious virus and adware problems with my computer and I don't know that they put that in there. How to stop? If I call the place that fixed, they will probably charge me for fixing when it should be an easy fix.

    The page don't will NOT LOAD, it fills just the bar of address, and if I hit enter and then it loads... help please.

    Thank you very much.

    Do you already have an add-on named QuickStart? Maybe he leaves it behind.

    There is a parameter hidden what appears on new tabs, which you can modify as follows:

    (1) in a new tab, type or paste Subject: config in the address bar and press ENTER. Click on the button promising to be careful.

    (2) in the search above the list box, type or paste newtab and make a pause so that the list is filtered

    (3) double-click the preference browser.newtab.url and enter your favorite page:

    • (Default) page thumbnails = > subject: newtab
    • Blank tab = > subject: empty
    • Built-in Firefox homepage = > topic: welcome
    • Any other page = > full URL of the page

    Press Ctrl + t to open a new tab and check that it worked.

    Success?

  • 21 Firefox tells me that I should upgrade to Adobe Reader 10.1.7 Despite this already, and this shift is not the first time that this happens, but why?

    This is the Plugins section and the option to update. In the two previous versions of Firefox, plugins check tells me that I have to upgrade to a specific version of the Adobe Reader software, despite the fact, I laready do. Does this mean that Firefox is vulnerable, or player? Is it a problem or just a glitch in software. Given the complexity of the player (which I need for work reasons) I hope that this does not indicate a serious and non-transitory problem.

    Hello, I think it's just a bug in the plugin check website - your system details also show that you are using adobe reader 10.1.7 which is the latest version available for windows vista, then you can safely ignore the warning on the mozilla plugin check page (which is probably looking for Player version 11.0.3 adobe has not been available for windows vista However).

  • Satellite T130 (part PST3AE) blue screen BSOD

    This netbook is just out of warranty of 12 months (2 weeks) and does not on Windows 7 with a blue error screen shortly after the connection.

    It won't reinstall from the recovery partition (it blue screens during the installation of the OS) and a test of memory using the test installation of the recovery partition does not indicate an error with memory of the netbook.

    It has always run hot enough, and I barely saw the announcement of service about upgrading the BIOS to provide warning against overheating.

    I wonder if the overheating has damaged the netbook and now, the only use it has is as a paperweight or if I have to spend the money to replace the disc and try reinstalling the operating system.

    I must admit that I expect a better life of a Toshiba product than just 380 - odd days of use and I am considering what action is open to me under the law of consumption.

    Someone else had a similar problem?

    Hello

    I ve got two Toshiba laptops and never had any problems.
    Of course the laptop can always begin a malfunction it is nothing unusual, because the materials can damage all of a sudden.
    The laptop is therefore covered by the warranty.
    Standard warranty is valid for 12 months, but if you sign up on the page of Toshiba notebook you would get additional year.
    However, in my country the retailer warranty covers products (any product it is) always 24 months long.

    Back to your question; BSOD is the result of serious hardware or software problem.
    A higher temperature may affect parts of portable computer s like for example the RAM modules, and this may cause BSOD.
    This happened with my first non-Toshiba Notebook I bought 10 years ago.

    I guess that you are not sure if it s related to the software or hardware so I recommend recover laptop using the recovery disc or HARD drive recovery.
    If the BSOD happen again even if the laptop was found, then you should check the cooling modules. Clean it with a jet of compressed air. Blocked fans can lead to higher temperatures, which leads to BSOD.
    If this is insufficient, the laptop technician must check the hardware.

    So you n t have a Toshiba laptop?
    This forum is created for users of Toshiba

    Anyway, the BSOD could be caused by serious software or hardware problem.
    Each tool/software pre-installed could cause a BSOD
    I think that you should first check if the BSOD happen using the computer with the new OS preinstalled.
    If the BSOD happen again, then you should check the RAM modules.
