Using a Canon EOS Rebel T7i with a EFS 18-55mm lens, my Lightroom Classic CC 2019 always gives me the following error message whenever I try to go into lens correction "unable to locate a matching profile automatically" and I have to manually add that information in.

However, I take the SAME photographs to one of the computers at college and it has no problem filling in that additional information automatically. It is obviously not the camera model or the lens because the school PCs have no problem automatically filling this information in.

The only difference is that I have more recent updates to Lightroom than the college PCs do so obviously one of YOUR GUYS'S updates MESSED that feature up!!

It should be easy enough to correct. After manually selecting the correct Make, Model and Profile, go to the "Setup" line immediately below the "Enable Profile Corrections" checkbox. It will probably be showing "Custom" at that point, so click on the Up/Down arrowhead icon at the right, a menu will appear, then click on "Save New Lens Profile Defaults". That should ensure that the selected profile will in future be automatically applied when enabling Lens Profile Corrections on images taken using that particular lens.

I'm using the Sony A7 Mark II with two lenses, the Sony FE24-70mm F4 ZA OSS and the Samyang AF 14mm F2.8 FE. The challenge I have, the pictures I took at the same evening in the same serie sometimes the profile is automatically added but 1 or 2 pictures after are not. When I'm trying to add the profile like described above, it doesn't show the lenses I use. When I try to copy the settings, including the lens profile, nothing happens. I've added two screenshots so you can see what's happening. Any suggestions ?

Obviously, the second screenshot is NOT the right lens.

strangely, you're right ! How the f.. did that happen ?! I just checked my camera and it's set to RAW but when I checked some of the images it's JPEG. I've never touched those settings during the shoot. How does this happen..??

Could be the program selection. Some Canon cameras switch from raw to jpeg when you select the ‘green’ program, for example. When you select another program, the camera switches back to raw, so you never realise what happened.

wow...well, one thing I will definitely check before shooting if the camera is still in the RAW program. I looked at the SD Card, some pictures have been taken in RAW and some in JPEG, whilst I've never touched the menu to select other than RAW. Could this be happening when switching lenses somehow ?

That seems unlikely to me, but of course I do not know the peculiarities of each and every camera.

I think I figured it out. There's an option to connect the camera to your smart phone. In this way, you're able to change settings on the camera with the use of the smart phone. Also, you would be able to actually see the pics you just ook. I've noticed when you use this option, the camera a jpg file instead of RAW. The jpg is much smaller in size then the RAW one, therefor the uploading is much quicker.

So, lesson learned, I guess.
