EOS Bodies / Canon 1D X firmware poblem?

« on: December 31, 2012, 10:22:32 PM »

I've run accross a problem with my 1D X when shooting in manual (M) mode.  If I have the camera set in Manual, the 2-second Self-timer enabled in Drive mode, and use Live View, the camera freezes up after taking a shot.  I've verified that it does this with both the 17mm TSE and 8-15mm fisheye zoom (just happened to be the two lenses that I was using...).  I have to turn the camera off and remove the battery to recover from it.  I went back and tried the 2-second self-timer and live view with the AV mode and it worked OK so it seems to be specific to Manual mode.  Can someone else with a 1D X confirm this behavior?  I'm thinking it may be a firmware bug; not a problem with my specific camera.

Thanks...

EOS Bodies / 5DM3 HDR Article

« on: March 14, 2012, 08:04:22 PM »

I ran accross a 5DM3 HDR article on Canon's Learning site.  It's about what I expected but it would be better if it could save the resulting file in a 16 bit/color file format.  At least the input files taken can be RAW and you have the option of saving them but of course that is the same as a 3 shot bracket.

EOS Bodies / 5DM3 Video Odd MB/sec requirements

« on: March 07, 2012, 10:01:55 AM »

From an article on Canon's Learning Center about the 5DM3 and video:

"* HD 50 fps or 60 fps recording places the greatest demands on memory card speed, especially during ALL-I recording. Required read/write speed during HD 720p ALL-I recording for CF cards is 30 MB/sec; for SD cards, 14MB/sec."

Anyone know why it wouldn't require the same MB/sec rating for both types of media?  the MB/sec should be driven by the video recording parameters; not the card format shouldn't it?
