Odd 6D behavior?

Discussion in 'Canon EOS' started by mark_stephan|2, Mar 8, 2018.

  1. I have an elderly friend that uses a 6D same as I do. Her camera is probably 3 years older than my camera. We often go out together to take pictures of different things depending on the season. We also share lenses. Her camera does the following; 1. The little red light that comes on after taking several pictures stays on for ever, something in order of 15-20 seconds. 2. Looking at our pictures taken of the same scene with the same 50 f/1.8 STM lens and same camera settings her images sometimes looks under exposed. 3. After taking a picture using her Lexar SD card we can view the images on the back of the camera but not on her laptop or my home computer. I've loaned her a SanDisk SD card and that may have resolved the problem. I also want to mention that she recently purchased a cheap eBay battery grip and that came with 2 batteries. Could these items cause any problems. She cant afford to send it off right now but I told her she can pay me back later so off it goes to Canon in Virginia tomorrow. Thanks for your response!
  2. Is she saving RAW or JPEGs or RAW+JPEG? I imagine which you choose will impact the speed of saving to the card. Perhaps the read/write time for her card is slower than yours (older type). As to exposure differences: are her settings the same as yours? Exposure compensation, AWB, metering mode, lock AE etc etc. Try to ensure they match exactly and then compare shots. I doubt the grip influences anything.
  3. I am thinking it is the difference in write speed of cards, this happens after several shots so it could be a buffering issue. And Robin brings up a good point with JPEG setting, the camera is doing in-camera processing on the JPEGs, there could be Noise Reduction settings like long exposure noise reduction, high ISO Speed NR, Highlight Tone Priority, Picture Style, Auto Lighting Optimizer, Color Space selection all could affect how fast the Digic 5+ takes to process each photo. Image size of JPEG and/or RAW all come into play. And perhaps battery voltage if low possibly could slow speed of processing.

    Also be careful using slow cheap cards, I lost about 4 hours of shooting Day of Rock in Denver, many band shots lost because of a 64Gb bargain Sandisk SD card I got for $10 at Wal-Mart on Black Friday. It did just that started writing very slow when the buffer filled, then I got an error and everything on the card corrupted and no software could salvage the shots.

    It was a painful lesson to learn. :(

  4. So Mark, it has been three months since your post. What have you resolved or should I say what has your friend resolved, if anything? Did she try a faster memory card. Did you two duplicate your settings? Also not mentioned before was the color setting, RGB vs Adobe which can have a large impact on how images look out of camera.

    Hope you follow up with us.
  5. Yeah, that's definitely card-related. Could be an old slow card, or a new, fast, bad card. They're computer chips in small cases. They get damaged or sometimes get fried. They also get counterfeited, and those are generally pretty crappy. Lexar has good guarantees on most of their cards. It would be worth looking into that.
