DMF bug on Alpha7 with firmware 2.0

Hi folks, I noticed something buggy about DMF with the 2.0 firmware update on my Alpha7.The problem is identidical with 2 different FE lenses (28-70 and Zeiss 55). My setup: I shot on DMF mode, magnification time = 2sec.So, the scenario is:- I press half-course => AF is applied- then I turn the focus ring => camera switches to zoom mode- then I stop turning the focus ring and... i get back to the normal (dezoom) view within a random time, varying between 2 sec to infinity. I checked that this behavior is reproducible on other alpha7 cameras. This bug is hugely annoying to me, because I mostly shot with DMF. Does anyone know how i could downgrade the firmware to an older one (1.20 for instance) ?Update software doesn't seem to propose such possibility... Thanks in advance for your help!Cwati  

Hi Cwati,
Welcome to the Sony Community!
Thanks for bringing this to our attention. We will forward your post to the engineering department for further investigation.
As for the firmaware downgrade, or going back to the version 1.20, that won't be possible. Once you update the firmware of your camera, you can't revert to the older version.
If my post answers your question, please mark it as "Accept as Solution". Thanks_Mitch

  • Bug in Macbook Pro firmware (2009 mid)

    Dear all,
    Recently, I bought a new Macbook Pro (2009 mid model). I found that there was a problem in illuminated keyboard. Logically, the backlight of keyboard should be darker if the light source of surrounding environment is strong. However, it is totally opposite!! The backlight of the keyboard will turn dark if the light source is weak!! I guess it should be the bug in firmware.

    I don't think that's true. In bright light, the keyboard backlight is off. When the light sensor detects that ambient is below a certain lux value, the keyboard backlight is activated. When the ambient light is +just below+ that value, there is still a fair amount of light in the room - in that case, the keyboard backlight needs to be relatively brighter to be effective. When the room is pitch black, the keyboard backlight should be relatively dimmer, since less brightness is required to see the keys if there is almost no ambient light. The same is true for the display - the brighter the ambient light, the brighter your display needs to be.
    What should happen, for example if you're in a brightly lit room with a dimmer switch - with room light at full brightness, the keyboard backlight is off. As you dim the lights, at some point the keyboard backlight will come on, and be at it's brightest (or as bright as you have the setting). As you continue dimming the room light, the keyboard backlight also gets dimmer. When the room light is all the way off, the keyboard backlight is at its lowest brightness.
    However, if what's happening is that in bright room light the keyboard backlight is still active, that is a bug (if everyone with your configuration is experiencing it), or a glitch (try a PRAM reset), or a hardware problem with your machine (call AppleCare).

  • Some bugs in E5-00 Firmware ver. 071.003

  • DON'T Install Snow Leopard on early MacBook Pro with Firmware password on!!

    I'm going to summarize my postings from yesterday because I don't want anyone wasting their night like I did.
    Many of us who upgraded from Tiger created a Firmware password to ensure that people won't be able to wipe and re-install the HD for sale if the computer gets stolen. I also note that, like me, many have been suffering the recent won't wake from sleep issues that make it feel like the HD is dead. Sometimes it starts from sleep, mostly it's a real hassle to get it to wake up and when it does it's generally in safe sleep mode. I managed to find a "halfway" good fix for that issue by changing the sleep mode from 0 to 3 in the terminal, found a useful script by Googling the problem. Fixes 90% of my issues on that score. But I wanted to install Snow Leopard to "hopefully" fix that issue for good.
    HOWEVER, if you have a MacBook Pro 2006-2007 model and the original install disc is still Tiger, WARNING TURN OFF THE FIRMWARE PASSWORD if you created one before you attempt an install. Otherwise you'll be completely stuck in black screen **** and you cannot restart from the Snow Leopard disc once you have it in, neither can you eject it because you never get that far.
    The computer, after installing Snow Leopard just gets stuck on the grey screen for a while and then goes black. The computer will not boot from the Snow Leopard disc, Techtool Protege or Leopard disc and the BIGGEST PROBLEM is; you can't Zap the PRAM with firmware active to try and continue installation as some other posters have suggested. Basically, you're screwed.
    To get the Snow Leopard disc out I rebooted in Windows and ejected the disc, then put in first the Leopard disc... didn't work... then rebooted, ejected and put in the original installation disc with Tiger, that did work but no firmware password reset!!!
    The only solution was for me to wipe the disc, reinstall Tiger from the original install disc, which was the only one that worked. Once I could restart the computer again in Tiger, I was finally able to reboot from the Leopard disc and disable the firmware password.
    Then I restarted, zapped the PRAM and using the Leopard disc, restored my machine to its former self with my Time Machine back up. Ran Techtool Pro 5 to fix permissions and rebuild volumes etc. and now have it working again.
    I think I'll leave Snow Leopard for a while since I don't know whether the zapping PRAM works during install and frankly, don't have the time to go through this entire debilitating process again. If anyone does manage to get things running on the earlier MacBook Pros please let me know how it went!
    Anyway, just thought I'd give people a heads up on the Firmware password thing... it's really a bugger on the older models because it wasn't originally included on the original install disc leaving you with no options!!

    Sorry, just wnated to post a comment not question, wasn't sure how to mark it!

  • Make Eyebeam 1.5 work threw WRT160N with firmware 1.02.2

    Greetings:
    I have an eyebeam 1.5 that I have tried and tried to get to work with my WRT160N with firmware 1.02.2 with zero sucess.  The Eyebeam will work perfectly when hardwired to the cable modem but will not work via the WRT160N wireless router.  Please help and tell me what to do do get this to work.  The eyebeam does not use an ip address to connect to the service but rather a domain name netcenter.republicsolutions.net. In the settings IP address is set to discover global address STUN is turned on and is set to discover server and ICE is enabled as well and xtunnels is set to never.  In the presence tab it is set to "peer to peer".  In the security tab  signaling transport is set to "automatic"
    Also the Eyebeam works perfectly on the wirelss router at work so this is indeed a Linksys issue.
    Thanks

    Well try to upgrade the firmware of the router which can be downloaded from the Linksys/Cisco website. Once the firmware is downloaded, you can proceed with the firmware upgrade even without Internet connection.
    • To prevent upgrade failures make sure that your computer is connected to the router using an Ethernet cable for stable connectivity. Upgrading the firmware wirelessly may cause permanent damage to the router since wireless connection may be unstable during the process.
    • Use a different Internet browser if Internet Explorer doesn’t work or use a different computer to perform the upgrade.
    • To prevent failure disable firewall to ensure that the upgrade will not be disrupted.
    • Make sure that you downloaded the correct firmware and version for your device to prevent technical problems that may damage the router.
    Here is the link for Upgrading the Linksys router's firmware: http://www6.nohold.net/Cisco2/ukp.aspx?vw=1&docid=e9c2361ee7974d75913e61386a712188_4030.xml&pid=80&r...
    After upgrading it is recommended to reset the router, then reconfigure it again and then check the status.

  • 5300: Problem with firmware upgrade

    Hi,
    I have Nokia 5300 Xpressmusic with firmware version 4.7. I have recently download Nokia Software Updater and tried to update my phone via USB cable connection. The software runs fine, it identifies my phone correctly, checks for update & tells me that V5.5 is available & downloads it successfully. The problem is that when I press the 'Upgrade' button, 1st it reboots my phone in 'Test Mode', then the 'Preparing installation' window remains on the screen for a couple of minutes & then it gives out an error saying "Connection to phone lost". I've tried reconnecting my cable but it still gives out the same error. Fortunately when I took the batteries out & reinserted & started my phone, it turned on successfully with the previous firmware version. But I still cant get it upgraded. I switched to another PC & tried it there but it still gives out the same error at the same stage. Kindly help me out with this, what is going on here?

  • I have a WRT54G Wireless modem with firmware version 1.02...

    I have a WRT54G Wireless modem with firmware version 1.02.1 Mar 4 2003. i down loaded the latest firmware for the modem but i can't install it. I get the erroe message"incorrect image file".
    What is wrong?

    Which version of the WRT54G do you have?  If it is not clearly stated on the router, go to Wikipedia.org and search for WRT54G, then you can use your router's serial number to determine which version of the router you own.
    The version of the router is important.  Each version has a different set of hardware in it, so each version takes a different firmware.
    You can only load the firmware that corresponds to your model and version.

  • Airport Extreme Simultaneous Dual-Band port forwarding broken if only TCP ports with firmware 7.6.1

    When configuring my Airport Extreme Simultaneous Dual-Band router, port forwarding is broken if you only specify TCP ports to forward. This is with firmware 7.6.1. What happens is that after you hit the Update button, when the router comes back and you open the port forwarding entry, the IP is still there but the port numbers are missing.
    I tried all different port numbers and ranges and nothing would stick if i only specified TCP ports. If i added UDP ports with the TCP ports then it would save them. And if you add a new entry with only UDP it saves them too.
    Now this is with adding a new port forwarding. I already have existing ports being forwarded that only have TCP. They are still working. I believe i added them with a previous version of the firmware.
    Any one else see this issue? Any ideas?
    Maybe i should perform a hard reset and reload a saved config.
    Peace,
    Dan

    I haven't seen the issue but you could just downgrade to an earlier firmware:

  • ACR + Canon 5d2 with firmware upgrade?

    Canon released a frimware upgrade for the 5D Mark II which claims to fix the "black dot" problem and a SRAW1 banding problem. Very little feedback has been reported by users, but some reports imply that the new firmware creats a new RAW file that can not be properly processed by current raw converters. Claims are that old converters will convert the new RAW files, but with some wierd color shifts.
    That claim is fueled by Canon's own statement that you must get an updated version of their DPP program to properly process the new RAW and SRAW files. But what about Adobe Camera Raw? Can anyone confirm or deny that old/current versions of ACR will not properly process 5D Mark II raw files?
    If true, is an update to ACR coming? More important, will Adobe be able to apply whatever correction is necessary within the DNG Converter? So those of us with CS3 who are stuck forever with ACR 4.5 can process firmware-updated 5d MarkII raw files correctly?
    Not a critical problem, because you can apparently function quite well without the firmware upgrade. But the upgrade is a path of no return. Once upgraded, you can't go back to the original firmware version if problems with ACR exist.

    Looks like they might have done pretty well with the dots (although this
    is just one small example):
