Lightroom 2015.8: Canon 70D Wifi Tethering broken with the new update

Before the latest Lightroom update (2015.8) I had no problems using WiFI tethering using my Canon 70D. I went to do a shoot tonight and I couldn't get it to work at all. Nothing has changed on my computer other than updating to the most recent version of Lightroom CC. After several hours of troubleshooting I've determined that the something in the update broke wifi tethering for Canon.

Here's what I did:

I started the EOS utility and turned on my Canon 70D to connect to my pocket router. The camera connected fine to the router as well as my computer. When I opened LR and clicked Tether Capture, Start Tether Capture, filled in the data and clicked Ok. All I got was "No Camera Detected." I closed LR and opened the Canon utility and the tried remote capture. It worked fine there. I uninstalled and reinstalled LR. No joy! I uninstalled and reinstalled the EOS utility...no joy.

Finally I looked to dll/plugin files which come from the Canon SDK kit that control the wifi tethering in Lightroom.

These files are found in Windows in C:\Program Files\Adobe\Adobe Lightroom\tether_canon.lrplugin. The files in particular are EDSDK.dll and EdsImage.dll. I backed up and tried replacing the .dll files from the latest version of my EOS utility found in C:\Program Files (x86)\Canon\EOS Utility. When I tried the tether capture in LR I then got an error message that it couldn't start properly.

Next I backed up all the files in the C:\Program Files\Adobe\Adobe Lightroom\tether_canon.lrplugin folder and deleted them. I replaced them with EDSDK.dll and EdsImage.dll from LR 5.7 (old laptop still had it) along with tether_canon.exe and tether_canon.lrplugin. I tried tether capture again in LR and wah lah, it worked!!


This tells me that something is definitely wrong with the files in the newest update. 


If you can't tell this isn't my first rodeo with LR and tether capturing and that's why I knew to check the files out. Can you please pass this on to your developers to see if they can recreate the problem and hopefully come up with a fix that doesn't manually reverting to a previous version of the tethering files.


If you need any other information please feel free to let me know at anytime!

Greetings Mark,

I am unfamiliar with wireless tethering to Lightroom in this manner. I would be happy to be corrected however ;-). 

Normally with this type of setup you would set EOS utility to do the capture and deposit the files in a folder where Lightroom using the File>Auto Import settings would monitor the folder and automatically ingest your images. Then, as each image is captured by camera shutter press, it is sent (via the EOS Utility) to Lightroom.  Shutter presses can also be done by the EOS utility. 

As far as I know, Lightroom has never supported File>Tethered Capture by anything other than a cabled connection. 

Is it possible you were using the Auto Import previously and not Tethered Capture?

No, Lightroom is actually capable of wireless tethering exactly the way I described. I've used it like this for years with no issues. 

Essentially it works like this: 

You still have to start the EOS utility launcher (Not EOS Utility 2) this should put an icon in your system tray. Right click on the icon be sure to check Do not launch EOS Utility Automatically when camera is connected. This will prevent the Canon capture software from opening. Lightroom won't work if it's running at the same time. 

You'll need to setup wi-fi on the camera to connect directly to your computer or a router. Just follow the wi-fi steps on the camera directly. Eventually your camera will get to a point where it will wait to see the camera connection. The utility launcher should find the camera and it's MAC address. You only have to do this step once unless you clear your camera's wi-fi settings. 

After this is done, open Lightroom and Start Tether Capture. Fill in the settings you want and click OK. You should get a popup that has button to click the shutter remotely and it show your camera as connected. 

The popup will show your camera, shutter speed, f/stop, ISO, WB setting. and Develop Setting + a shutter button. You don't have to use the shutter button in the popup, you can still use the camera directly for everything. 

Why I prefer this over auto import:

While yes you can setup Lightroom to watch the folder while using the Canon remote capture one thing I love about using the wi-fi capture (cable for that matter) directly in LR is the option of the popup for develop settings: Same as previous.

This will allow you to take  an image that automatically imports to Lightroom. You can then go to the develop module and tweak the image how you want it to look. The next image you take will automatically process the new image exactly like the previous image.

This is a huge time saver for me! I did a gymnastics shoot and I used wifi tethering. The setup stayed the same and I took one test shot and tweaked it the way I wanted. All the subsequent images were processed immediately upon capture. When I got home from the shoot all I had to do was some minor retouching and cropping. My images were pretty much print ready! The parents were always so impressed how fast I was able to get them their pictures after the shoot (typically a 2-3 day turnaround).

Of course without doing the fix I stated above the 2015.8 updated crippled the wi-fi capture. I had to do a shoot last night without. It wasn't a big deal but it did cost me a lot more time.  

The only caveat to shooting via wi-fi tethering is the speed. If you shoot full-size RAW files then it can take quite a while to transfer. I typically shoot in Medium RAW and the transfers take about 3-5 second per image. I also use a pocket N-Speed router to connect to versus Ad-hoc (direct camera to computer nic connection). Connecting via a pocket router will give you the fastest speeds. 

Give it a try sometime if you have this option. It works beautifully!!

I've had a similar problem with my Olympus OMD-E5-Mark II after upgrading to Lightroom CC 2015.8, but I used "wired" tethering.  When I reverted back to 2015.7, tethering worked again, as usual.

FYI,

Same problem came up for me, too: wireless tethering for Canon 6D broken in 2015.8.

Since the  auto-import-dialog fails to open as well (as reported and acknowledged in other thread), this has become a no-go for working wireless since LR2015.8.
