I was shooting a client gig last night and because I needed to make prints at the event, elected to use Lightroom tethering to my MacBook Pro to get the images into Lightroom as they were shot. On numerous occasions during the evening, the camera appeared to lock up and the data transfer lamp remained lit for minutes at a time. I would see delays of several minutes before captured images would get to Lightroom, and then after waiting a while, things would go back to normal. Then in a short period of time, everything would bog down again. By stopping tethering, the issue vanished completely and I was able to shoot as the event required. On a break, I tried tethering again and the same issue replicated itself very rapidly. In my pre-shoot tests, tethering appeared to work, but I did not test at the volume that the event required (3 images every minute and a half).
In the past, tethering would lose connection randomly but the connection stayed up all the time, however the huge delays in transfer made the tether function more a hassle than a boon. Have others experienced this with Lightroom 2015.3? The environment was very simple. Canon 1Dx with a Tether tools cable to the MacBook Pro running El Capitan and Lightroom 2015.3
Any advice will be appreciated. Earlier in the week, I had done a similar shoot using Canon's native tethering tool and never experienced these issues, and was shooting at a much higher rate, using the same physical equipment.
Thank you very kindly Tanuj. The only thing I didn't try, was resetting my Lightroom preferences. The only other application was Apple's Numbers that was being used to capture the names of the subjects and the frame numbers. I've used this before without issue. There is always the issue of Apple's incredibly annoying Photos application always launching when the camera is connected, but I quit it every time it launches - although I have yet to discover how to disable the darn thing permanently.
I can try resetting the Lightroom preferences, but the article appears to refer to LR3 and LR4 and I am somewhat reluctant to have to recreate all my preference settings. I did test using Canon's EOS utility and had no issues with delay, and today also tested successfully under a much higher load with Capture One 9. Not what you folks want to hear, but it's a what's so.
