60D + 400 5.6 - focus point not showing

I was doing a few shots around the yard yesterday with my 60D and 400L. I was using One Shot and when focusing it would lock and beep but when I was looking at the photos later in Zoombrowser (ZB) the focus squares would all show as black (none highlighted red). Any ideas what might be causing this? When I view info, ZB shows me the other data like ISO, Shutterspeed, Aperture, etc...

Are you using back-button (AF-ON) focus, or shutter button focus?

Back button focus. The red square in ZB seems to show up with my other lenses though. Although my 60D consistently front focuses with all my lenses.

I used to have a 60D, but honestly believe all (most?) Canon cameras work the same. I just tested this on my 80D and 6D; both work this way.

When using BBAF, if you have your thumb on the AF button when you release the shutter, your AF point(s) will show up. If you DON'T have your thumb on the AF button, the AF point will NOT show up.

Ok thanks!

This is the most common cause for this, there is something about using lens correction profiles in camera also causing the indication to be removed, but I'm not sure if that is a feature on the 60D.

I have the peripheral illumination activated for the 400L. This option isn't available for my Sigma or Tamron.

I have PIC turned on all the time. I still get red focus squares.

It's not Peripheral Illumination Correction, but an actual lens correction profile, similar to those you get for LR, that correct for pincushion etc. I think the 60D might be too early for that option, and for the bodies that has it, it is only available for canon lenses. It turned out to be the cause in a quite recent similar thread. I posted to that thread too, but doing a search of my recent posts doesn't help me find it. I'm sure it was in the last two or three weeks though.

Yes, I jumped the gun a bit with that answer. I said PIC, and meant all available corrections. Canon in-camera corrections take care of (depending on the camera/lens):

PIC
Distortion
Chromatic aberrations.

The 60D is/was capable of correcting PIC and distortion. I'm not sure which bodies do what, but my 80D and 6D do all three with some lenses.

WRT LR5.7, every lens profile I've ever used corrects distortion and vignetting (PIC), with one caveat. You only get PIC with auto-aperture lenses. Makes sense. If the aperture isn't recorded, the software can't know how much to correct your image. I ran into this with the Rok 14mm f/2.8. LR could correct distortions (within reason, the lens has huge mustache distortions), but did nothing with vignetting.

If any of these three photo-flaws are present in a lens with no profile, LR offers manual corrections.

So I looked in ZB last night at different shots taken with my Sigma, Tamron and 2 Canon's. I can't really see any sort of pattern for when a focus box is highlighted and when it's not. For each of the lenses sometimes one was highlighted and other times it wasn't. I've been shooting with BBAF for a few years now and always compose, focus and shoot the same way. The only times I do it different is when I'm trying to shoot BIF and hold the BBAF constantly, using AI Servo, while also holding down the shutter button.

If focusing was active when the picture was taken, and no corrections that would move things around in the image are enabled, then you'll see the AF point in the finished image.
If focusing was inactive, like when using manual focus or when AF with the trigger button is disabled, and no other button takes over that role when the picture is taken, then there's no AF point to record. There really isn't if you are using One Shot AF and recomposed either, but the camera can't know that.
If distortion correction is enabled, the camera will "massage" the image slightly after taking it, which implies that the exact position of the AF point versus the image is no longer known. Hence it's not shown.

I did not know that. I just confirmed it on my 80D. I will make the assumption that it applies to my other bodies, also. Thanks. Now I know why I sometimes get, and sometimes not get, the red AF square in DPP.
