Had 80D about a year, just taken my 1000th photograph this weekend. Mixed results still. Still struggling with autofocus, not always getting the focus where I thought it was going to be.

Silly mistake this weekend, still had the white balance adjusted from a previous shoot and all the ones from this weekend underexposed. Managed to salvage a few with raw image white balance adjustment.

Ah well, carry on practicing.

Does anyone uses the Auto AF zone (the whole 45 points) for one shot still (landscape) photos? does this work for you?

I did a walk with this camera and a 24-105L, using those settings and pretty much all the landscape photos focusing infinite came out of focus. The viewfinder light up most of the AF points (and I confirmed it at home), but they are nowhere close to being focused. It seems that the camera decided to focus on the closed subject (even out of the AF point area), but it tells me the the whole AF points confirmed focus, which is wrong.

Photos of closed objects focused properly.

On my 450D with the same lens, I used the auto AF as well, but the viewfinder would only light the AF points that were REALLY focused. I knew that if I had a AF point triggered, that zone would be for sure focused.

I sometimes use it for still shots and so far didn't have a problem. I don't remember if I ever used all 45 points for landscape shots, though.

Your macro shots are exquisite. Aside from the obvious fact that you are getting killer photos, how do you like using the 65mm on the 80D?

Thanks!
I like the MP-E a lot. It's a bit tricky to use (like even a slight breeze kills any shot and it quickly teaches you that diffraction is a reality) but all in all it is easier than I thought (and lots of people claim it is). The 80D's 7 frames/s help a lot in shooting short bursts when slowly moving back and forward to focus.

Yesterday I made some tests at home with the camera mounted on a tripod and after each AF made thru the viewfinder, switching to liveview (at 10x magnification) for checking the focus accuracy on that frame spot.

The camera worked perfect with 1 point AF with pretty much any AF point across the frame, there were only one time that it said multiple times it could achieve focus on the bottom right corner of the frame but it was always out of focus, the AF point was over some roof tiles that might tricked the AF system.

Using the zone AF also worked great, didn't have much issues.

Large Zone AF, things start getting worst. If I focus the same area over and over again (static city landscape), I can see the distance scale on the lens jumping between values after each AF focus request, even if all area over the AF zone is at the same distance (infinite). This means the AF is not accurate between shots, leading to some out of focus shots.

45 points automatic AF, pretty useless for this type of photography, worst then the previous mode, not consistence at all. My current theory is that the camera checks all AF points, and light up the points where focus could eventually be obtained. But then it seem to take into account the closer AF point and the more distant AF point and somehow average out the distance between them and focus there, in the middle of nowhere...
Either that or it thinks some AF point achieved focus (but it didn't) and decides to focus there, but most of the times I couldn't find ANY spot on the frame that was focused correctly.

Now I don't know if this is a problem with my camera or its just the way this AF mode works....

The Large Zone and 45-pt Automatic AF both focus on the closest subject under the points. If you want ensure that the camera focuses on something specific, use the Single Point or Zone modes.

I understand that.

My issue is the camera displaying on the viewfinder AF points over the infinite (supposedly telling me those spots are sharp), but they are not!

Why would the camera light up AF points like a xmas tree all over the AF area frame when only a very small portion of the image is sharp? Sometimes I can't even tell where the focus is, it seems that it averages the focus distances of each AF point and focus there in the middle of nowhere...

This is not a challenging AF situation, its a static landscape on a sunny day...

To me what would make sense would be for the camera to choose the closest AF point and focus accurately there. If no other AF point will be focused, well too bad, no other AF point will light up. But this is not what is happening.

Do not light up AF points that won't be sharp, is that wrong to ask?

I went out today with my old 60mm macro lens on the 80D, hoping to take some close-ups of Spring flowers. It was windy - as usual - so I tried the macro lens on this little scene, and I was pleasantly surprised with the result, given that I don't suppose this type of image is what this lens is really intended for. I've had this lens for some years and the auto focus has long since stopped working, but it shows we shouldn't give up on half-forgotten lenses. It was a nice change to be using manual focus on a prime lens.

Took a couple of shots of another ladybug today. This is a stack of nine images and I must say I'm surprised at how well Affinity Photo handled it:

Wow! The bokeh of that pancake lens looks very decent, this encourages me to take that lens out more. :lol:

The only problem I see is that you take way to few photo's, I've had my 80D for 6-weeks and have passed the 5K mark already :-)
